Question:

What kind of valve packing material should I use for my shutoff valves?

I don't have one single water shutoff valve in my house that will shut anything off completely. It looks fairly easy to repack them, and I have the tools, and there are instructions all over the internet. The question I have for the experienced among you is what packing material do I use? I have heard graphite thread and teflon tape and even joint compound.Is one better than the other? Easier to use?Also, if there are any pitfalls I should know about before I undertake this, please advise.Thanks in advance!

Answer:

Well if you talking about the water shutoff valves under sinks then you need to first shut off the water comming into the house at the main shutoff valve near the street , Or at a line comming into the house that connects up to the valve you are trying to fix or you may take a slight bath while trying to fix the valve that wont shutoff. Then Go to the shutoff valve you want to repair in that line where you shut the water off at and unsrew the handle at the base of the handle shaft using two wrenchs to hold both the nut on the shaft while using the other to hold the shutoff valve .this will prevent twisting the valve right off the connecting lines. Most of the time you will find it has a rubber gromet attached by a screw to the handle shaft.this is what you need to replace with a new rubber gromet which you can get in an assortment box at wal mart or homedepot or lowes for a low price. If you are using teflon thread or jointcompound you are repairing a Pipe joint leak where water is leaking externally of the pipe,not a shutoff valve leak .
For stopping leeks use teflon tape to lub your valves use plumbers grease it s good idea to have a tube around not expencive
