My water heater is leaking a bit. I'm excited, because I've been looking forward to replacing it with a tankless unit for a long time.

Any recommendations on brands for tankless water heaters?

Never heard of it, but the reviews are decent on this model:
https://www.lowes.com/pd/Rinnai-Super-High-Efficiency-7-5-GPM-160-BTU-Indoor-Natural-Gas-Tankless-Water-Heater/999959665

Definitely going to go with a Super High Efficiency unit, that was a great decision on my furnace, plus the tax credits, of course.
I'm most likely going to get professional installation, if only because it makes getting the credits easier in MA.

Anything else I should know about selecting a tankless unit?

You have to have a water softener. And your in coming ground water temperature will affect the GPM rating it can produce.

A whole-house filter is not enough? (currently using GE FXHTC filters)

I do have hard water, but as long as I replace the filter on schedule it hasn't been a problem.

My old man told me that in Vermont, they are requiring some kind of special mixing valve to be installed on top of water heaters (I think it's an anti-scald device?). He also said that it cost him $600 to get one installed.

I've never heard of such a thing. Is this a wide-spread requirement?

Sorry man, I wasn't busting on you, I'm just a little spergy about terminology, and was genuinely confused.

Here is one more factor to consider:

Both propane and oil are delivered products, so you need to evaluate the local availability and price. Where I live, there are a million oil companies competing for you delivery business, but virtually no one has propane tanks, so I'm guessing that propane would be a more expensive then it might be elsewhere, and potentially have a longer delivery lead time, as well.

loving hell. I finally borrow a truck, buy my water heater at Home Depot, bring it home. Three days later my old man shows up to help me install it, and we open the box. Two HUGE loving dents in it, looks like they dropped it off of the top shelf. And yet no damage to the box?

Now I have to do it all over again, starting with borrowing the truck...

The real tip is to buy from a plumbing supplier instead of a big box store.

Yup. I had a guy lined up that I wanted to use, he said that the Rheem water heaters he supplied were "better then the crap at Home Depot". But I had a $300 credit from Home Depot, and I'm kind of broke, so this was the cheapest out of pocket solution.

The replacement one they got down for us had a hole punched in it. Thankfully, I noticed this one right away, since there was a hole in the box right over it. The third (and final) one on the shelf had no damage, though.


EDIT: I spent a little more and got the Energy Star model, because I get a MA rebate. It's got one of those auto dampers, so I have to plug it in. Anyone install any of these yet? How new is it?

I love my brand new Rheem water heater... but now it keeps shutting off.

Seven flashes, three second pause: "System in Lockout/Presence of Flammable Vapors detected"
Unit is in an open, mostly furnished basement with good ventilation, and NO source of fumes.

First time I called the 800 number, I was told the reset: turn unit off and then on, and then turn the temp dial all the off, then all the way on, 7 times.
After a lengthy discussion, the tech tells me that the problem is THE loving CAT BOX, which is kept about 10 feet away. Apparently cat litter dust is a hydrocarbon?

It first happened after about 3-weeks of flawless operation. Then it happened once, and then a week later, twice in one day, and then again last night, so it's getting worse. They told me to move the cat box, but my house is small, and there really isn't any other good place for it.

Options:
1. Maybe I could wrap some cheesecloth or an old sheet over the intake grids at the base of the heater, to keep the dust out?

2. Can I just disable the sensor? There is no source of hydrocarbons nearby, except for the natural gas that feeds the water heater.

I'm going to call in again, but I thought you guys might have an opinion.

This is why the safety device is there. Are you completely 100% sure you don't have a minute gas leak? It wouldn't be surprising after an install.

Once that's ruled out, I'd look at an exhaust fan for the cat box if it really can't be moved. Lux feline pooping experience.

Possible that there is a minute gas leak. But, both the woman and I have really sensitive senses of smell, I think we might have smelled it. But I will recheck.
Also, the first time it happened, it was an unusually warm day, so we had all the windows in the house open, with a strong cross breeze in the basement. This is why I immediately ruled out gas.

Is your cat somehow producing an exponentially-increasing amount of poop, so as to explain the increasing frequency of shut down? I'm with glynnenstein, you probably have a leak. They're not uncommon. I was talking to a home inspector just the other day, I was proxying a house he was inspecting, he says he finds about one a day.

Look, it's what the tech told me... he said it was a goddamned nightmare before they figured out that their new hydrocarbon sensors were being tripped by proximity to litter boxes.

I just got off the phone, they are sending me a new sensor. I may just try cheese clothing the old one first.

I'm not saying it's impossible it's the cat box, but your description of an increasing frequency seems suspect with regards to that source. Unless you just got the cat? Otherwise, I would expect a cat's hazmat output to be fairly consistent.

Nope, cat is an old lady, and the box was never a problem for the old water heater.

However, I really think the issue is with the LITTER DUST, and not the cat poop. I use an unscented, low-dust litter, but I guess that still isn't enough. We keep all of our root-cellar type foods down there, so it's not like it's a dirty or dusty environment.

Interesting, I figured it was the cat litter dust, but this guy says it's the ammonia:

quote:

The Flammable Vapour Sensor

Did you know your fuel powered water heater has a safety switch that cuts out when it is exposed to certain levels of flammable vapours? That means chemicals, paint, ammonia from kitty litter, or other flammable scents have been exposed to your water heater. For safety reasons, your water heater will shut down. Once the vapours have dissipated, it will reset. However, everytime the sensor trips and resets, it is not being reset to zero. This means that it will take lower levels of exposure to flammable vapours for the water heater to kick out and eventually it won’t be able to reset.
How can you prevent tripping the flammable vapour sensor?
– Don’t keep chemicals in the same room as your water heater
– Ensure your mechanical room (or where you keep your water heater) has proper ventilation
– If painting near your water heater, turn off your water heater and air out the room before turning it back on
– Don’t keep your cat’s litter box near the water heater
How do you reset your flammable vapour sensor after it has tripped?
– Check your owners manual for manufacturer specific instructions on how to reset it
– If possible, turn off and unplug your water heater, then disconnect your vapour sensor. Place the vapour sensor in a well ventilated area and leave it for 90 minutes to 4 hours (vent out the water heater area while doing this). Reconnect that sensor and turn you water heater back on.
– Relocate any sources of flammable vapours from near the water heater
– If your water heater doesn’t reset, contact a service provider to replace the part

Being with out hot water is a pain, so follow the above steps to decrease the likelihood of being stuck with cold showers.

I have 6 (yes, six) cat boxes on a platform less than two feet from my Rheem high-efficiency unit, which I installed myself two years ago. Never had a problem, and there's clumping cat litter dust everywhere, including the top of the water heater, which I have to wipe down periodically.

Voting leak or bad sensor. Or change your box more than once a month :v: I have gone too long between changes & the ammonia smell is almost enough to bring tears to your eyes. Water heater gave no fucks.

The tech on the phone said that this was a relatively new issue. My unit was built October 2016.
Could just be a bad sensor, but from what I've googled, I'm inclined to believe the tech. The fire department came to my house with their sniffer and found no gas leaks.

Only one cat, I clean the box every 1-2 days. In summer, she pisses outside, and it's a lot less to clean.
6 smelly cat boxes is like my worst nightmare. I'd have to sell the house.


Jadunk posted:

Def sounds like a bad sensor to me. The quality of new styles sensors on newer high efficiency tanked and tankless units are pretty trash. (and will probably improve rapidly, I know they did when power vents first came out and had all those issues with pressure / temp switches)

New sensor is coming in the mail today. I'm still tempted to just defeat the switch, though.

Bypass the sensor that warns of a dangerous build-up of vapours? In your heart, you know this is not a good idea.

Agreed. :smith:

But my previous water heater didn't have one, and it never blew up.
Plus, the cat litter thing just pisses me off. Since they sent me a new sensor, I'd feel like an rear end in a top hat if I didn't move the litter box, and the new sensor got ruined as well.

This got no love in the Fix it thread, so trying here. It's a battery issue, but for Sump Pumps.


I have a battery back up system for my auxiliary sump pump. It has two deep cycle batteries, Glentronics Pro Series B-2200. Here is the owner's manual in PDF:
https://www.stopflooding.com/assets/2/6/Manual_Pro_Battery_Inst_sheet_08_(Cur).pdf

And here is the Amazon listing:
https://www.amazon.com/PHCC-B-2200-2400-Battery-Backup/dp/B00DPF8LIK/

$200 a piece, without any acid. My sump pump company wants $300 for them filled and ready to go. Ouch.

The manual very clearly states to never add more acid to the batteries, only to top off with distilled water. Which I've been dutifully doing for the last few years. The controller/charger unit is telling me one of the batteries is dead, and needs to be replaced...

Is there any reason I can't just check the acid level with a battery acid tester, and then adjust the acid level? You know, like we used to do with car batteries?

I have a hard time believing that the battery is already completely dead, they just haven't seen a lot of use.

Speaking of outdoor spigots, am I the only one who has trouble with those through the wall anti-siphon silcock valves? I'm dutiful about always turning them off on the inside and draining them fully every fall (I live in cold, cold New England), and yet they still seem to wear out fast?

I have to replace them every 3-5 years, they always start leaking. Mr current one leaks bad enough that eventually it will fill the hose up tight.

My own take is it doesn't matter that the base itself leaking water, but rather that water is getting into the base in the first place. The leak is probably further up.

I had a detachable kitchen faucet that was leaking inside itself while I was using it. It turns out the head attaches to the hose inside with a basic threaded fitting, and the way I was using it had slowly loosened the connection. It was a simple act of twisting it back into place.

Sounds reasonable, thanks.

I tried taking it apart last night, and was stymied by lack of access to the set screw. But it was late, and I was grumpy, I'll get it today.



kid sinister posted:

You replace what? The seat washer? Don't hulk out when you tighten them down. The rubber will last longer. Check out the valve seat the next time you take the stem out. Make sure there isn't any crap in there that could keep it from making a good seal: old rubber bits, globs of solder, cracks...

I just replace the whole thing, ie. solder on a new one. Like the other guy said, it's internals that wear out. I can take it apart, clean it, lube it up with oring lube, and that usually buys me one more season... and then it just leaks again.


PainterofCrap posted:

Also, be sure the sillcock is pitched downwards, towards the exterior. If it's pitched up, water can stand in the unit & freeze.

But of course! hands you a jar of Grey Poupon

Since I do this, I technically don't have to winterize the valve at all, but since I have the internal ball valve shut off, I do anyway.

So yeah, the orings were worn, but the valve cartridge wasn't in great shape, either. I've never worked on a kitchen faucet before, but I have a Kohler, so it was pretty easy. I got the seal kit and the valve for $19 shipped Amazon Prime, can't really beat that.

kid sinister posted:

The internals shouldn't "wear out". They're brass. It's the rubber that can just be replaced, unless you got frost damaging your sillcock every winter. Is this a regular sillcock or a frost free one? Vacuum breaker?

It's the kind that self drains? With a long tube to pass through an insulated wall?

Anyway, this one is only 3 years old, I'll take it apart and have a look.

Yeah, really high water pressure will make your water heater leak, I'm glad I got that pressure reducer installed. I still have plenty of shower pressure, though.

So, I probably should have gone to the Plumbing Supply store instead of waiting two days for my Amazon Prime shipment: I underestimated how gross my kitchen would get in two days without a faucet! Anyway, I was staring at the brass fixed parts for a few days, and I noticed a barely perceptible leak from it. I don't think my cold water shutoff valve doesn't close all the way? I tried opening and closing it a few times, and it didn't help. Is this normal?

Oh, and for that guy with the sump pump, my yard is an active swamp in the spring time, and when it rains it floods right up to my basement door. My sump pump runs 24/7 for most of April.

My advice is to put together a disaster kit, mine's in an old milk crate. Submersible pool pump, 20 foot garden hose, extension cord. I keep it right next to my little generator, and together they saved my bacon when I lost power for 5 days after the Noreaster in winter 2018. Pop the top off the sump, lower in the pump, and pump into my set tub to drain (in most places, it's illegal to pump your sump into the sewer, but under emergency situations it's not a big deal).

I even have a battery back up system with an auxiliary pump (two deep cycle marine batteries), but if it needs to run constantly, the batteries are good for only maybe 3 hours.

Was it PVC or CPVC? PVC is allowed for cold water distribution in some areas, but CPVC is way more commonly used, and required for hot. The pipes look similar. CPVC was a popular alternative to copper before PEX started to become common in the US.

PEX can also sometimes look like PVC if it's white and you don't look closely.

Ah good point, I didn't read anything printed on it, it just looked like plain white PVC to me.

My HVAC company talked me into one when I ripped out my old oil boiler, and I like it. Has it's own condensate pump, helps keep the humidity down in the summer time.

I got a Ruud 50G heat pump water heater last year in my garage while I was getting Solar and a garage subpanel installed and it's been great so far and in my mild Sacramento, CA area climate only takes $6-$10 per month to run. The great thing is the City offered some huge rebates to get one installed and I didn't have to do any paperwork at all. Dumping the old janky vent stack and sealing up the roof was a bonus.

I got back 50% of my front hall closet when I ripped out the flue from the old oil boiler. Of course, now I have to fix all the dry wall in there, but I'm excited to have a full closet.

The downside to an all electrified house in a cold climate is that in the winter time I have to turn the heat pump water heater to straight electric mode, or else I'm just stealing heat from the rest of the house.

If you're heating your house with a heat pump it is more efficient to leave the heat pump water heater in heat pump mode. Electric resistance heating is terribly wasteful.

That was my first thought, but then I got into a Thermodynamic theory death spiral... if the house is a closed system, and electricity is the only heat source, it seems wasteful to add heat to the house, just so another electric appliance can remove it to heat water. Entropy has to catch up at some point, right?

You make a good point about the source of heat being more efficient (the house HP vs the water heater electric elements), but the other problem I run into in winter time is that the HPHWH makes the basement too cold.

Based on various internet opinions, I decided on the three-way diverter valve instead of the ball valve ladder. The manual for the heat pump depicts the ladder in the diagram in the manual, but the text of the manual implies that the three-way valve is the better way to go.

Anyway, getting close! Base is built, electric is installed, I redid all the plumbing on the pump and filter, and now I just need to decide on final plumbing design for the heat pump.
Here is the layout, the pump/filter and heat pump are almost, but not quite, 22.5 degrees apart.



For plumbing, I can put the valves on the near side, or right by the inlet/outlet for the heatpump.

Option one, valves on farside:



Longer hose, shorter PVC.


Option two, valves on nearside:



Shorter hose, longer PVC. I also feel like I would have to support this one permanently (it's sitting on some bricks right now).
