pex mainline conversion

jpeaton | Posted in Construction Techniques on November 28, 2010 10:04am

So my plumber ran all the pex for my new house and then when he returned to tie the 1″ line into the meter he didnt have the fitting he needed so he ran 3/4 for about 16″ He says this is not a problem because the 3/4 line is so short and so far, without a benchmark and a only a very short time in my new house, the pressure seems to be fine. Anyone see a problem with this? It is a 1500 sqft house 2 beds/2baths. Thanks for any insight, I just want to make sure its cool before i backfill and walk away.

    Well, the 3/4 might be OK if it weren't for all that JavaScript clogging it up.

        You've apparently installed some sort of browser tool for "SeekSpeak" (http://www.seekspeak.com/) and it's injecting that stuff for you.

  2. DanH | Nov 28, 2010 11:05pm | #3

    It's probably OK but half-arsed.  Unless you live way out in the sticks the plumber should have come back the next day with the proper fittings and installed 1".  But you'd only notice the difference at high flow rates (eg, run the shower and the washing machine and flush a toilet at the same time).

    >>>It is a 1500 sqft house 2

    >>>It is a 1500 sqft house 2 beds/2baths.

    With that size house I think you'll be fine. PEX is pretty slippery and 3/4" will let lots of water through.

    To put it in perspective, we've got a 3,600 sq. ft. house with a suite. There's a total of four bathrooms, two kitchens, and the whole thing starts with a single line of 3/4" PEX  coming from our well. No complaints.
