    New home owner here! Had a line crack while changing the faucet, my first instinct was to run down to the basement to shut the water off. Of course I was in a panic and shut off the valve coming into the house to the pressure tank (well water here) and then the valve coming out of the tank...

    Shallow Well Check valve on top of well point. Yes or no?

    I have been accumulating all parts for a hand driven shallow well. I have a 1 1/4" well point, Simmons 1721 that has inside threads at the top where a 3/4" nipple can screw in. In speaking with a neighbor with a similar well, he is down 28 feet with 8 feet of water. Everything I see on the...

    Check-valve for Moen 2400 valve

    I have a circa 1970-71 condo with a Moen Bath-Sh0wer valve with a built in diverter. I assume this is the 2400 series. Being 50 years old, I'm not sure when the cartridge was last replaced, and the spool if ever. In cleaning this up, I did put in a new diverter (amazing what it is supposed to...

    Hello. Searched the forum, but couldn't find an answer. My water well set up has an untreated hose bib for watering lawns before my water softener, and filters.

    Make a pump quiet check valve with a wye?

    I have a typical loud thump when my ejector pump goes off, obviously from my check valve. I went to the big box store but they don't sell 2" quiet/silent/klunkless CVs. They actually have a licensed plumber working there, which is a surprise. He told me when he installs pumps he puts a wye...

    Do I need an additional check valve on top of the pump?

    I know this has been covered before, but I've heard it both ways. About a year ago I decided to take on installing our well pump myself. The local pump installer would only offer PVC drop pipe and I prefer poly. I am not a professional and I listen to what those that know what they're doing say...

    Water softener Check valve needed?

    So I'm just an average DIYer so treat me like an idiot. My water softener and sulfur machine both discharge vertically, run along the wall in a 5/8 (inside diameter) pipe and then tie into an 1 1/2" pipe. Sulfur remover is extremely loud when it goes off but I'm more worried about the discharge...
