Unhappy Stop & Waste Valve


First thank you reading this post of mine.

I am a "total" novice in plumbing and need some guidance based on what's happened today at home.

I have this 1/2" CPVC pipe running in by basement that goes out into the garden basically for connecting the garden hose.

The CPVC pipe in my basement has a "stop and waste valve". I got this name by doing some research on google and its got a tiny black nut kind of thing below it. I shut this valve every winter and open it every summer. Here's now it looks -

Since summer is setting in I opened the valve 2 days back. Today I almost fainted when I saw a inch of water accumulated in the room in the basement where this pipe runs through.

What's happening is a fine stream of water is getting sprayed from one of the corners of the black nut. When I shut the valve it stops. So I have shut the valve.

I called 2 plumbers and they said replacing the valve would cost $175-$250.

Is there any way I can try doing something myself? I have a Lowe's close up.

Truly appreciate your help.

Fixing CPVC plumbing is easy and certainly something you should be able to do as a novice.

Being a novice, it probably would be a good idea to pick up a plumbing book at your local Lowe's and read up on the procedure to repair and glue plastic piping.

Supplies you'll need are a new valve, a coupler (female-female), a short piece of CPVC pipe, and CPVC primer and cement. Tools you'll need will be a hacksaw, and maybe a knife for cleaning up the cut edges of pipe.

Shut off the water to the house first! Cut out the bad valve. Glue the new valve in on the house side. Then add a section of pipe to the other side of the valve and use the coupler to connect to the pipe going outside.

Only thing i would use a ball vavle and not a gate valve when you replace the valve. The guys at lowes should be able to point you in the right direction.

doesn't he need to go back in with a stop and waste type valve? it sounds like the system has to drain back for winterization.

if you do install a drain back valve pay close attention to the arrow on the side and how it drains. you will have a big surprise when you turn it off if you don't.
