pex a

Hi- relatively new to PEX and plumbing and would welcome your advice. My builder used Flowtite valves throughout my new build and one has already failed me. I’m looking to replace all of them, starting with the laundry room. I currently have a drywall team handy, so now is the best time to...

Greetings. Can I use a pinch clamp on the Polybutylene side of a Pex to Polybuylene fitting? The fitting is cold expansion pex (Uponor). I have fittings, but only have pinch clamps convenient. Although the clamp manufacturers don't state polybutylene compatible in the information I could find...

I recently saw a rough-in and noticed some of the stub outs on the water heater were supported by expanding the pex after it was pushed through a metal bracket. It felt solid and it was a support method I'd never thought of. With the tight fit and differing expansion rates, I was wondering if...

Planning a 2nd floor bathroom remodel and will be taking the opportunity to replace the 65 year old copper with PEX-A in the whole house while I'm at it. Decided on trunk & branch (vs home-run) and wanted to solicit some advice/opinions on sizing. Attached is the current layout. 3/4" copper...

Hello friends, so getting ready to run the PEX A in the house. I am bringing 1” PEX off of the 3/4” copper from the street to the utility room. I'll run a bypass with valves just in case. I bought pro PEX brand 1” NPT to connect to the in/out of the filter system (putting brass unions on...

How many fixtures can reasonably be ran off a 3/4" hot loop with 3/4 to 1/2" reducing T's running to the various fixtures? I have included a photo of my preliminary design below. Also, do I need the check valve between the hot and cold connection tee back into the water heater? Thank you in...

Hello everyone. I am remodeling my jetted tub/shower down to the studs. I currently have 15 year old 1/2 CPVC pipes. I will be installing a 2.5 gpm shower head with a 2.5 gpm shower wand to a Delta 3-way multi valve. The shower valve is supposed to be rated at 5.3 gpm at 40 psi, 6.5 gpm at 60...

My water meter is 3/4" but I can't figure out the easiest way to connect 1" PEX A to it. Right now I have 1" galvanized pipe. I looked everywhere and a water meter coupling with 3/4" threaded to 1" PEX A does not exist. Propex seems to sell water meter couplings to PEX but only for 1" or 1 1/4"...

Hello- I'm in the middle renovating my house and I have been trying to get my hands on some 1/2" Uponor PEX A (Aqua PEX) but no one seems to have any in stock. I decided to go with PEX A (Uponor in particular) based on all the good reviews, hoping to avoid future issues. I even purchased the...

I have a piece of PEX with an expansion fitting coming off a 90 and going into a drop elbow. The connection is at an angle and feels like there is a lot of stress at the fitting. Is this considered acceptable?

Hello, I'm about to start work on the re-piping for a 1952 ranch built on pier and beam in Central Texas. I'll be using PEX-A pipe and expansion fittings/manifolds. The question regards insulation of the PEX piping. In the code for City of Austin, it mentions that supply 'piping' in an...

Long story short - after chasing pin holes in my copper pipes for years, I've decided that a major re-plumb with PEX is my only alternative. Anyway, the leaks have only been in the horizontal hot water pipes so they have to go. I believe the culprit was the old water heater that was in this...
