Hello, I have this plumbing on the incoming water line coming into the home (See Pic). The pipe I have circled in black has sprung a very tiny leak . Does someone know what this type of pipe is called and why does the diameter get so constricted? I assume it may have to do with the fire...

Hi, I'm trying to install a shower system with 3 body sprayers, a rainhead and a handheld. The connection sizes are all 1/2 in. We did a crude GPM test filling a 5 gal bucket from the hose and we got ~7.5 GPM. Our whole house is on 1/2 in copper -- reduced down from 3/4 straight off the meter...

Complicated question here but I’ll start: we have a well that feeds our Main house, (over 1 inch line, unsure) then goes to 3/4 in the basement, two filters and a neutralizer, then out running 3/4 line 225 ft winding uphill to a cottage. Pressure issue is up there. a guy dug the whole thing...

What size trap arm/drain is required for a tub/shower that has a trap arm length of 30"? The trap arm has 1.5 p-trap, runs 30" and dumps into stack. This line does not have its own vent, it is vented by the 4" stack. Reading 908.2 of 2006 UPC states, "Each wet-vented section shall be a...

First off let me thank you for opening and reading this post. Any advice will be appreciated. I currently have a 1948 3500sqft (3700sqft with walk in attic storage-currently unheated) house heated by 19 wall convectors and a Burnham series II boiler. Last winter 2-3 of the radiators...

So I had to do basement renovations which led to removing the majority of my existing hydronic heating line feeds(amongst lots of other things). It was fairly haphazardly run, so this wasn't the worst thing. Previous setup was direct return 1" main with mostly 1/2 feeds to the radiators...

Need some professional advice on a potential upcoming project. I am looking to install a water softener. The main line into the house is 1" copper. My plan was to branch off with pex to the softener, and return to the main line, about 100' round trip. Would there be any issue with downsizing...
