No, it was 1/2 and I went back and forth on rerunning supply with 3/4, but the amount of drywall I would have had to tear out and replace was ridiculous. I still get pretty good flow, it would just be nice to have higher pressure with both opened all the way up. I'll experiment with heads and see.

Well I filed for my 45 dollar repiping permit and it was accepted. Placed the order for the PEX, should be here by the end of this week. Might start Thurs/Friday if it gets here in time, otherwise its the weekend. How long do you let the ProPEX expansion connections sit before you go full pressure? I know it doesnt have a cure time or anything like since no glue or cement, but unlike that metal expansion fitting style, I have read in places that you need to wait X amount of time. The Uponor site doesn't really cover any of this.

If you have any problem , and a ring wont seal you can try using a heat gun on it. (when the pressure is released off the system obviously.)

Also I got the slip-fittings with the stops builtin, so hopefully wont have to worry too much about correct overhand distance and stuff.

Thanks again! I've finally broken the concrete up and am about to install my new 2" line but I have a question about the P-trap configuration at the shower. I found the main 4" drain line in the floor pretty much where I expected it, and by my estimation the highest point of the 4" pvc pipe is about 4" below the solid concrete layer. Now I know I need approx 1/4" slope for every foot of pipe I run and it's about an 8' run to the shower so I'm looking at 2" of rise from the shower to the 4" wye. At this point I'm wondering which way to configure the p-trap to ensure I have slope and I'm below concrete. By my calculations, since the 2" part of the 4x4x2 wye is slightly lower than the top of the 4" line, I have approx 5" of space at the wye from the main stack to the lower concrete level. If the 2" line runs up 2" in the 8' run, then my 2" shower line should be 3" below the concrete when it finally reaches the shower right? Now since the clearance is low, I'm wondering if it's possible to configure the p-trap so that the shower is a straight vertical drop into the U part of the trap, then the trap rises to a 90" bend and that same 90" bend then travels horizontally on the slope to the main 4x4x2 wye. (Of course vented along the way). Is this possible? Or do I need another two 90" bends to give the water level a slight drop before the horizontal run? The attached pic has both examples.

Ahz posted:Thanks again! The top pic is correct, while the bottom trap is an S trap and will give you a lot of issues. Why can't you dig down further and put the p trap further into the ground. That is the norm even if you need to jack hammer out dirt or rock to make the p trap fit.

Thanks, Actually the top pic is ideal for me as the horizontal run will begin at a higher elevation in relation to the downstream 4x4x2 wye. It will be easy to bury the lower section of the p-trap in sand and I just wanted to ensure I would have good flow as I wasn't sure I would considering the horizontal run. My other question may be more local code related, but I just measured the horizontal run and it's just about 8.5 feet from the p-trap to the wye. Are there any issues if I grade the horizontal run slightly more than 2" like 2 1/4" instead? Or would 2" be the maximum? What is a good way to measure the slope over the run? I was thinking of using a 4 foot level and measuring the offset every 4 feet from the next highest point, and if the offset is 1" per 4' when I should be fine right?

Ahz posted:Thanks, It's fine if you over grade it. It won't cause any issue with the flow. Also I'd suggest getting one of these graduated levels that show grade. You can put it right on the pipe and it will tell if its 1/8, 1/4/,3/8, or 1/2. http://www.homedepot.com/h_d1/N-5yc1vZ1xim/R-100081706/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053

My "Replace CPVC with PEX in Basement" permit was accepted and mailed to me. PEX arrives Wednesday, although also closing on my home refinance loan Wednesday, so probably wont start the replumb till late Wed night or Thursday. Gotta get it all done and inspected on next Monday though since drywall gets installed Tuesday.

I found out after my first CPVC install that I did it with the wrong glue On each squeeze of the expansion tool you are supposed to move it 45 degrees or 1/8th of a turn. Do you need to rotate clockwise the entire time or could it be rotate 45 clockwise, rotate 45 counter, etc etc. Wondering if I need to spin the drat lines around the head or can just go back and forth as needed.

Basicly expand pipe, contract expander rotate 1/8th expand, contract and rotate. Keep doing till you get the entire head in the expander. If may come with some black grease you can use. To apply remove head, apply thin layer of grease to cone of expander. Put head back on and you are good to go.

grover posted:The code limitations for the length of horizontal run before hitting the vent stack are based on 1/8" or 1/4" as appropriate. If you go steeper without moving the vent, you run the risk of the pipe not venting properly and siphoning out the P-trap (or S-trap). Ya I see what you are saying, but I didn't go in detail because he was only talking about running that a little more then 1/4 per foot.

You barely have to turn the tool, like an 1/8th inch. After each expand, pull out slightly and rotate briefly, start to expand and then the head will stay in place while the handles can rotate for positioning. Here is a video of it but he doesn't do a great job rotating.

I guess I will figure that one out when the tool gets here tomorrow. From what I understand the heads screw on to the tool. Do they clip on or attach without threads? It seems like if the head can always be rotated it would eventually reach a point where it is fully tight or loose enough that is just falls off I bought some extra fittings and have plenty of extra pipe. I will just play around for a while before I start doing any of the actual fittings. Worst case I just buy like 300 bucks worth of shark fittings from Home Depot for my entire setup :iamafag:

Are there any issues with two vent stacks connecting (above the highest fixture of course) really close to each other? Since I needed a cleanout when my new shower vent comes up from the floor, the best position to come out of the floor was right beside the current vent stack that it's going to connect to, within 1". My plan is to run the vent up about 6' and then connect them with a 90 bend on the new line into a T on the vent line. Are there any issues with this? What if the connection sort of pushes the stacks away from each other since the connections seem to stick out about 1" or more per line. If the lines are too close to connect, my other thought was to install a slight bend in the vent stack with a 45, then a T(which joins the new vent to the current), then a 45 to return the vent to its original position after the connection was made.

One inch between the vents won't be enough room. You will have to offset one away with two 45's. You could even get away with using a Street 45 and a regular 45 to give you the needed offset.

Got all my spiffy PEX poo poo today, honestly the ProPEX thing isnt that bad. The expansion head sits inside the connector ring and can be spun around by itself. Now the only paranoia relates to if I spun it the right number of degrees or not Got about 40-50% of the plumbing built alongside and ready to be lifted up. Need to make some of the longer runs that connect the various sides, but its all good. Only problem right now is I forgot to buy a reducer fitting/ So I will have a dedicated 3/4 hot water line going to a single bathroom faucet . Going to get a 3/4 to 1/2 sharkbite to make that connection to the existing CPVC.

You can go turn clock wise then counter clock wise and you will be fine. And over sizing a water line will do nothing bad, and you will get more volume.

Did the french want some sort of revenge for designing that drat expander tool? Its the most awkward tool I have ever used, and extremely painful to use. I try to brace it on my hip, only to have to slip down towards my front side. I can't just reposition it mid-expand cause I dont want to screw up the PEX, so I end up stabbing myself just above my balls. Also I figured out a way around my missing reducer. I found a creative way of using a T joint which now spits out 1/2 hot in the direction I need it to go.

You think thats bad, one inch pipe in the cold is a major bitch. If I have to hold the pipe and expand it above me I usually rest one handle on the left forearm while holding the pipe with the left hand. Then I use my right to expand it.

Is there any reason one couldnt reclaim previously "used" plastic PEX fittings? For the hell of it I took a razor to a cut out one and carefully sliced through the PEX tubing. Even went as far as tearing the final paper-thin section of pipe to not nick the fitting itself. Is it just the fact that it takes about 10-15 minutes per tube fitting to remove the old crap that they are considered junk? I know the brass ones you can just melt the old tube off. Don't plan on using any of the old fittings, but it came to mind when I realized I have no spares of a certain fitting left.

One leaking joint, and to top it off its not even one of the PEX connections technically. My male PEX to female 3/4 NPT fitting is leaking at the threads. I had perfect amounts of thread compound on the male threads, brushed evenly around the entire thread surface. Should I try teflon tape instead? I have tightened and re-tightened this fitting and it still has a very very small leak. Its a brass to brass connection, using TFE paste if that matters.

Three-five wraps of dope clock wise ( if you are looking at the face of the threads , and wrap it clock wise from there) then the tape wont get backed out when you tighten the F.I.P (female Iron Pipe)
