    I’ve added an RO filter in my mechanical room which is directly below my kitchen. the RO output is through a 3/8 inch OD tube. My refrigerator and a drinking water faucet are connected to a 1/2 inch PEX pipe. I need to connect the 3/8 tube to the PEX, but have not found any suitable, RO safe...

    No plumbing in old house...

    The 3bed, 1bath, 1,400 sqft house was built in the '50s if I remember correctly. The previous owner deleted all the plumbing except for the copper inlet. I already changed the size from 1/2' copper to 3/4 Pex and its first stop is the toilet. I plan to run 3/4 Pex throughout the house reducing...

I have it connected to a hydro air handler on the space heating closed loop side but for now I am only going to flush the domestic hot water side.

    Water Dripping From Shower Head

    I've read what I could about this topic and have made a number of changes but still have the problem. I am renovating a house and one of the showers I ran 1/2" PEX from the valve to the shower head. When I turned on the tub faucet it would drip quite a lot from the shower head. I never...

    Re-piping pipe size question

    Hi, I am planning on re-piping the exposed pipe in my basement from copper and galvanized steel to PEX. Currently, my meter spits out 3/4" (which whoever put the piping in immediately cut down to 1/2"). My main run is then 1/2" and splits off to 1/2" for other runs. I am thinking of getting...

    Leak at 1" copper to pex connection

    Hi, I found dampness in my garage and investigated to find that there's a leak where a copper pipe connects to a pex tube. How should I replace that fitting? Looks like it goes from copper to pex to another pex. Was that done just to bridge the gap? Also this is the house hot water supply line...

    PEX for a Water Main

    In my area (Southern California) most plumbing companies seem to run poly pipe for the water main. Why isn’t PEX A a more popular option? From what I understand it needs to be sleeved, so does the foam insulation count? Also, I know it needs to turn into copper prior to going through their...

    PEX & minimizing the number of fittings

    I've used PEX a few times as a DIY homeowner. I recently came across a few videos that show installations where numerous fittings were used in PEX runs, which I believe is contrary to the great benefits (in terms of reducing installation time, reducing the potential for leaks, maintaining...

    Can you make your own pex supply line?

    I was reading a plumbing article earlier today and it had this photo in it. It looks as if it’s a pex supply line with a push fitting at the end. Are these type of supply lines allowed? I’m curious because I can no longer purchase the hand tight only sink supply lines at my local hardware store...

    Pex To Hot Water Heater

    This gas hot water heater was installed three years ago, but I am concerned about the size of the pipe and 1/2” pex pipe being attached directly to the hot water heater. The tenant has not complained about anything, but I am curious if I should take the preventative-maintenance approach and...

    PEX Fitting Organization

    Does anyone know an easy way to organize PEX fittings? (especially in tight spaces like under a house) We use a fittings tray off of amazon which seems to work but a little wobbly and weird when the Viega crimps and cutters and hammer are all in tray as well.

    Sharkbite wont go on.... ??

    Got a 1 1/4" SharkBite brand coupling that doesn't seem to like pex pipe. I had to pound it on with a 2# dead blow hammer. Is that even close to normal? I'm using the copper inserts that were the ones recommended when I bought the fitting. Beating the other pipe in with a hammer will be...
