    Mortar or No Mortar - American Standard Cambridge

    I am about to set an Americast tub - Cambridge model - and am deciding if I should bed the tub in thinset or minimal expanding foam. American Standard says that it isn't necessary but it sounds a bit hollow to me when standing in it. Any suggestions are welcome. Thanks.

    1 psi pressure drop in 24 hours

    I have a 1 psi per day pressure loss (a bit less really) on an 90 psi pressure test for bathroom plumbing. I have soaped every joint and fitting, including the shower mixing valve, and do not detect the leak location. I have a sense that one of the temporary nipples, which are threaded into drop...

    I am channeling for above counter outlets in a kitchen remodel in a 1940 home and accidentally cut into the wall of the iron vent pipe from my kitchen sink. It's 1 1/2 inch galvanized pipe and embedded in the brickwork of the exterior walls. I probably cut a bit less than 1/16 inch and not...

    Any suggestions for grounding a security system panel? The installation manual for the system I am working on specifies an earth ground with no less than #14 wire.

    Pressure fluctuation in PEX?

    How much daytime to nighttime pressure fluctuation can I expect in a PEX system? I've got about 130 ft of 3/4" under 100 psi test and don't have a sense of how much variation I will see. I'm in Tucson so there's about a 30º swing from day to night... Thanks!

    Suggestion for no-stop couplings?

    Does anyone have any advice for keeping no-stop copper couplings from seizing up on pipe? I find that I can get them to move easily when checking fit but then they seize up after applying flux and sliding them onto one of the pipes to be joined. I can't get them to slide back onto the other half...

    Soft Copper in a Wall Cavity
