Water leaking from cut-off valve knob (clear plastic)
The cut-off valve is no longer shutting the water off to my toilet tank and it is also leaking a few drops right at the knob that you turn to shut the water off. How can I fix that?
Okay - an update. I went to Home Depot and the guy helping me said I needed to know what kind of flexible hose I have because there are several that have different end pieces that connect to the shut-off valve. He showed me and there was one with a washer that was cone shaped and one was regular and then one was really small. I guess I will have to wait now until Saturday when I will have more time and can shut off the water and take off the flexible hose and look at what the end looks like. I appreciate so much all the help you guys have been!!! You have no idea.
The most common toilet supply line is, as posted at post #10, a 12" long x 3/8" compression x 7/8" toilet nut. Of course, that doesn't mean that is what you have..., but it is highly likely!
Anyway, always best to bring the old supply line with you.
Since you have the compression shutoff, plan on purchasing a 5/8" compression x 3/8" compression straight stop (if pipe comes out of floor) or angle stop (if pipe comes out of the wall). If the place you purchase the shutoff starts talking about 5/8" OD or 1/2 ID stuff...just tell them that it needs to fit 1/2" copper tubing and transition over to a 3/8" compression x 7/8" flexible toilet supply tube.
You did good by posting about the possible confusion. Like going to a refrigeration supply house to buy a 7/8 long sweep elbow so it will fit 3/4 copper tubing Long sweep elbows are cool.
Ok...I'm in the process of repairing the toilet! I replaced the toilet fill valve inside the toilet but I am concerned that there is still water coming out of the shutoff valve at the wall. I turned the water off at the street and opened the faucet (cold water) in the sink and bathtub of the bathroom I'm working on. I have been letting it collect in a pan for a little while but guess I will go ahead with trying to replace it while the water is still coming out?
Open ALL faucets, especially the LOWEST faucets in the house like say at the sink in the basement...force most of the water to flow into sink down there instead of where you are working...
I ended up just replacing the fill valve and reconnecting the hose to the shut-off valve. It really shouldn't matter if it won't shut off all the way for now. I couldn't get the shut-off valve loose from the pipe coming out of the wall. I learned a BIG lesson though - don't use the shut-off valve in place of the fill valve if the fill valve isn't working properly! That is much easier to replace than the shut-off valve. I will say that I have every confidence now - thanks to you guys - that I could replace it if needed - if I can just get the nut undone.
Water was still coming out of the top where the hose goes up to the tank. The water wasn't coming out of the faucet in sink or tub though. I have had some trouble with that nut right above the shut-off valve still leaking a bit. I keep tightening it just a bit with pliers and then checking to see if it has stopped. I am afraid to over-tighten it - however I don't have alot of strength anyway. Just checked it and it may be also leaking just a tiny bit right behind the knob at that nut.
