I’m back with another dilemma! Remember when I couldn’t remove the dishwasher three weeks ago? Well, someone suggested cutting off the legs, and it did the trick. But now, I have a new issue.
I got a new dishwasher installed, but the plumbing is giving me problems. There’s a tiny leak on the adaptors, just one drop every 19-20 seconds. Any thoughts on how to fix this without calling a plumber or handyman?
#1 simply apply new teflon tape on the threads of the leaking connection
Or #2 remove all those connections and just acquire a reducer to install this and attach your dishwasher hose to it
Try adjusting all those connections but be cautious with the 2 ends. rab tightly with large pliers onto the left side brass connection, resembling a garden hose connection. After that, use a wrench (avoid pliers) on the right end connection and secure it as much as you can. Wipe off any moisture, take off the plate, and wait to see if there’s a leak.
Why is there CPVC connected to a brass valve? I would remove that entire valve and replace it with one that has a direct 3/8 connection.
It looks like the shut off valve may have leaked before, that’s where I would start to fix the leak. Use the correct fittings, as every fitting used is a potential leak spot. The new fitting for the hose doesn’t seem to be the right one based on the photo.
I would redo that entire piece. Too many adapters could lead to more issues. et rid of all those parts and install a new complete piece.
Bring it all the way to the valve! Just one nipple at the valve and you’re set.
That joint needs more Teflon tape. Take it apart, clean the threads, add more tape, and then put it back together.
Your plumber really messed up! He should’ve cut the CPVC and used a shutoff with a 3/8 end. Too many adapters and not enough teflon tape. I always aim for as few connections as possible. Less chances for leaks.
For now, let’s start by removing the leaky straight connector, cleaning the threads, adding new thread tape and a bit of plumber’s dope, then putting it back together.
Et rid of the white Teflon tape and switch to blue monster.
If the supply line already has a washer inside, you don’t need to use Teflon tape to prevent leaks. Alternatively, you can just use pipe dope paste on it.
You’ve got too many Mickey Mouse adapters just to find a brass 1/2×3/8 reducer to connect to the dishwasher supply line. And remember, avoid using Teflon tape if you have a washer in the supply line.
There are many ways to improve your physical health, such as exercising regularly and eating a balanced diet.
You could replace the CPVC and install a new stop valve to get rid of those extra joints, or you have the option to disassemble it and use Teflon tape and pipe dope instead.
If that connection has a washer, you might want to check that. Regardless, disassemble it and inspect the condition of the washer. If there’s a washer present, no sealant is necessary, just tighten it properly
