Hi, I (homeowner) am in middle of DIY remodel a guest bathroom on 2nd floor of a 30 years old house. I made the following plumbing work - 1. Copper to PEX for all water lines in the bathroom 2. Replace the Toilet flange, 3" elbow and about 6 inches of horizontal 3" section. Had to do...

@Reach4 the pipes will have Fiberglass batt behind it, the foam/Kerdi boards are for shower waterproofing, but have the side effect of keep pipes from getting heat from interior compared to drywall sheets.

Hi all, The small alcove shower(34x38) in the bathroom I am remodeling, has its plumbing fixture in exterior wall (6-inch). It had to be done this way because the opposite wall has 2 DWV pipes, including the main stack running through it. For the last 30 years it worked fine, behind the...

@jadnashua thank you for your reply! The shower had a fiber glass pan. and I will be using a pre-sloped foam pan from USG. I will post a photo tomorrow to get some advice on how to fix it. thanks again.

Hi, I just finished my guest room demolition for a gut remodel. After opened the damaged subfloor above standing shower, I found that the ABS drain pipe has no slope, I put a torpedo level on it and it's dead center :( The level drain pipe(OD 2.5) is about 1 foot long between the P-Trap...

Hi, Wondering if anyone had worked with these kind of shower trims before? Are these compatible with US plumbing standard? seems most of them are from Australia or Europe. https://i.pinimg.com/originals/33/82/4e/33824e56b3c8970c39cec08897711fee.jpg...

Sorry I didn't explain it well. I will have full access to the p-trap, I expect to replace the subfloor under the shower and toilet. Here is the sequence of work I plan to do. 1. Demolition. 2. Circular saw plunge cut the shower area subfloor to open up the drain pipes including p-trap 3. Cut...

Hi, I am about to start my guest bathroom gut renovation, one thing still not very sure and hope I can get some advice on the shower drain p-trap installation - I will replace the existing P-Trap since I need to move the center of the drain a couple of inches, also I am using Durock's...

Hi, I am a home owner and will be doing some DIY remodeling soon. Today I checked out a couple of new constructions near my house and found that the nail plates (protect pipes) and supply line stub-out plate/brackets are screwed onto the side of the studs directly, adding 1/16" thickness...

@hj thank you for your response. Are you saying IPS or NPT it doesn't matter? I have read in several places that they are different and should not be used together. I'd appreciate it if you could explain a bit more. Since they are going to be sealed behind walls, I want to be sure everything...

Hi, A while ago I purchased a Moen 3510 shower valve which has 'IPS' female connector, at the time I did not know the difference between IPS(straight) and NPT(tapered), and thought I could avoid soldering with that connector. Then I found Pex adaptor I purchased and all I could find on...

I am going to install a Moen 3360 and Moen 3510 combo for my shower, from the 3360 installation instruction manual: "The distance from the supply valve center to the center of the transfer valve must be a minimum of 12" (305mm) to assure proper clearance of the transfer valve escutcheon and...

Thank you! did not consider insulation before. The bathroom is in second floor so ceiling mount drop ear elbow is in attic. most piping would be in 2 adjacent exterior walls. When you say 'it's close to the middle, that's the best' - what do you mean, the hole is in center of the 2x4 (thought...

Hi, I am planning a guest bathroom remodel, I have a couple of questions that I can't seem to find answer anywhere - - I plan to replace copper pipes with PEX , and it will run horizontally in that room, at what height should I run the lines? (3/4 pex, with tee to fixtures) -...
