Replacing a faucet is easy; if you want to try. Getting a super to give a poo poo enough to open the wall is probably way harder.

Also for the non New Yorkers; in my limited experience, there is a lot more latitude in general regarding modifying rentals, like putting up walls or replacing a chandelier, in some places folks who lived on apartments for longer time periods have been know the straight up remodel.

It was a shock when I first moved there.

I have a somewhat odd plumbing issue I'm curious about. I have a faucet in one of my bathrooms that has developed a strange kind of gross smell when you first run cold or mixed water from it after letting it sit a bit. I can't really describe the smell other than it seems maybe vaguely bacterial, kind of a stagnant sitting water type of smell. It's not gag inducing but it's bad enough that I don't want to drink or wash my hands in it. None of the other faucets or showers or anything, hot or cold, have this problem. If you put the problem faucet on hot water only there's no hint of the smell, and if you run the cold water for 10 seconds or so the smell goes away until you shut it off and leave it for a while. This seems to indicate that the source of the smell must be in the cold water pipe and fairly close to the faucet. The faucet was used frequently until the water coming out of it started smelling weird. The water for this house is supplied by a well if it matters, and I have a water softener.

Has anyone ever heard of such a thing? Is it possible some sort of bacteria has colonized the cold water pipe somehow? What would it even eat?? Could the pipe just be degrading in some way? Although if that were the case then why only the cold side?

My condo board has been trying to get everybody to sign up to get our Pressure Reducing Valves replaced. I'm told the expected life span is about 10 years, I bought the unit when it was just about 10 years old and I've never replaced mine in the past 5 years, nor do I believe the previous owner ever replaced it. Installation of a new one will cost about $500 or a bit less if enough people sign up. I don't particularly think the board is trying to scam us, but I don't want to spend $500 just because I don't any better than to say no. Does it sound like a good deal?

How handy are you? A good 3/4" or 1" PRV is going to run you about $80-150; depending on the existing install setup, you might be looking at another $50 in parts/equipment (fittings, torch, etc.) and it'd most likely be 2-4 sweated joints. So if you're comfortable sweating your own pipe, you'd be looking at about $200 to install it. I guess it comes down to whether you want to try to do it yourself or pay the $500 and not worry about it.

Oh, and regardless of what route, make sure the PRV is NSF-61/372 certified since I"m assuming this is for a potable line. Which also goes for if you have someone the board chooses do it. You could even probably buy the PRV and any fittings needed and just pay for the install.

Get your water tested. It sounds like you have iron or manganese bacteria in your well. It's not dangerous, but it does what you're describing and will likely get worse without treatment.

In a previous place that had this it wasn't worth it to go full on shocking the well but I did put in a filter just past the pump that I would use to dump a bottle of peroxide in (with the filter out of the canister), run the water until I could smell peroxide at all fixtures, and then let it sit for 20 minutes. When you turn the water back on it spits and sputters and black death comes out (so take off the aerators - they will get clogged). That would resolve it for several months. Shorter time periods the warmer it was outside.

So it's manageable that way, and potentially curable for the long term with well work.

Pictures would help. If you have the space you want to put in as much rigid duct as possible with a flex hose just at the wall to the dryer. Bonus points if you can put in a secondary lint trap while you're doing this: https://www.homedepot.com/p/Tjernlund-8-4-in-x-8-in-x-10-1-in-Secondary-Lint-Trap-for-Dryers-Booster-Fans-LT4/302247480

I know I’m going to need the ridged duct and 2 45s. Do I need mastic or just the foil tape to seal it. If I do the secondary lint trap, how far down do I need to put it from where my dryer currently is?

E: what type of bracing do I need to keep the pipes secure? I’m assuming there is some sort of strapping I nail into place?

You should use clamps, not tape. They should be in the same area of the store.

Secondary lint trap goes close to the dryer. They are typically mounted just above them to make it easy to get at/clean.

Bracing depends on your run and what you've got around. If you need to hang it or attach it to a stud you can use HVAC strapping (basically nylon webbing) or pipe strapping.

Judging by the heavy burn and the solder glopped around it, that bottom elbow is a cold joint and is leaking. I’d assume that the shower feed is also and who the gently caress thought putting a receptacle in there was a good idea?

Open the other side & re-do.

Did they even bother testing it before the tub install?

I assumed you meant foil tape. I'd still use clamps. Or tape and then clamps.

I don't like to worry about an install failing and filling someone attic up with flammable lint for want of $10-30 worth of clamps.

You could also do it the old school HVAC way as you were alluding to earlier, which would be mastic but then also sheet metal screws. I think that's probably overkill considering there are readily available properly sized clamps for this purpose.

In the end, do what you feel is sufficient based on your circumstances. Just understand the risks and the relatively low cost/effort to go a bit over "good enough".

I know screws are a big no no for dryer vents because they accumulate lint. I saw mastic might not like the temperature and that foil tape seems to be the most recommended. I could do tape and clamps and feel good about it.

foil tape is good enough for dryer vent, the important part is to keep the ducts secure.

My problem with foil tape only is when the ducts aren't secure enough cleaning them causes leaks.

Belt and suspenders is what I was suggesting here. Because it's cheap and easy while you're already in there.

Remember my context: spent years as a firefighter and fire investigator. I got to meet someone on the worst day of their life on a regular basis. So yes, I may be a bit overkill.

Here's what would be most convenient. Everything is 2" and the shower is the only fixture using this vent. Black is existing, red is proposed new. From what I can tell (and you also implied) that washing machines can't be part of a wet vent arrangement per code. But hypothetically, what could go wrong? Suds coming up from the shower drain? Or the shower p trap syphoning off?

It sounds like each unit has its own individual supply line, PRV, etc., so "touching plumbing that affects everyone" for this application isn't much different than a homeowner touching their exposed assembly knowing the supply comes off a distribution main in the road that also serves other residents.

But, you know, plumbing isn't magic so I'm not afraid to touch it.

Hi Plumbing goons:

The Navien CH-210 combi heat and hot water propane boiler in the inlaw apartment on my house is dieing. The service guys I use have informed me that Navien no longer makes the low loss header for it and it's a piece of poo poo Chinesium product anyway so I should put in a new one. They said roughly 8000 to 9000 is about the cost to replace all in.

Does that sound right?
Would it be practical to go back to an electric tank hot water heater and a regular propane boiler?

That sounds insane. What replacement unit are they quoting you? Things in that BTU range are around $3200. If they are replacing it with the exact same one there is minimal labor. Even if it's a different unit.......that's a LOT of money over and above the parts cost.

I'd probably sand down the bottom half of the new spout before I tried to bend old copper pipe stuck in the wall.

Worst case you gently caress up sanding and have to buy a new $20 tub spout.

Tub spouts are about the cheapest metal they can find, so shouldn't be too hard

Help me, o lords of plumbum. Here’s my current situation:



The left is my hot water valve/cartridge. The right is a middle-set shower diverter valve. The shower valve is leaking when any water is turned on, regardless of path. I took off the handle and found the valve space filled with cement (?) and now I’m screeching to a halt to ask for help.

My plan is to pull all three valves and replace them with new as I’m 95% sure these are all original to the house, built in 1962.

I'm betting your previous owner had a leak out the front of the diverter and "fixed" it by shoving all that plumbers putty in there.

My diverter valve had a similar leak, but the PO put a bunch of putty inside the valve. It made removing it incredibly awful and tedious.

Get a screwdriver or pick and see if you can remove enough of the gunk to get a wrench on the valve to remove it.

If it's really really stuck in there after unscrewing the nut fully, the way I got mine out was by putting a vise grip plier on the stem, a tall piece of wood against the shower tile to protect it, and then Leveraging a pry bar against the vise grip using the wood as a fulcrum with gentle taps from a hammer. I had to work mine out 1mm at a time but it eventually came free.

Follow up: I have a different guy coming on Wed to go over it. He's less of a fan of the Instant hot water units than I am, so we are thinking about putting in an electric hot water heater and a propane boiler for heat.

Edit: In the meantime: I ran a PEX line from the hot water in main house to the in-law apartment so they could have hot water in the meantime. PEX and Sharkbites connectors all installed easily and they don't leak.

Was able to remove the old putty with a screw driver. Leaks more now so I’ll be picking up a set of valve wrenches from Harbor Freight to see if I can tighten the valve to stop the leak.

It's probably not the tightness of the nut that's the issue, it's the o-ring or packing.

In this picture below, the important seals are:
-The seat washer: controls the water moving between the shower head and the tub spout in a diverter valve. If you had water coming out of the tub spout when the shower was engaged, it would be this washer and it's mating seat piece in the valve that you would need to be inspected/replaced.
-The Bonnet washer: stops water from escaping around the nut that secures the valve to the valve housing in the wall. It could be leaking from here.
-The Packing washer(s): This stops water from coming up along the rotating handle stem. If this is leaking, sometimes tightening(or loosening!) the packing nut will fix it.


Because the putty in your picture is packed around the outside of the valve, and not up against the stem, I think the leak was probably from the bonnet washer.

You can buy any and all of these parts pretty easily in most big box stores unless you just have some crazy unique assembly. The best way to figure out what you need is to pull one of the valves out and compare to pictures on the internet. Or you can do what I did and buy an entirely brand new set of valve stems from a plumbing supply store/website. :v:

Any ideas on how to replace the overflow drain gasket with a ~1/16” clearance around the pipe and the tub and no access panel behind it? :confuoot:
