subject: Fix Your Own Plumbing - Main Water Shut-off [print this page] Plumbing problems are common to homeownersPlumbing problems are common to homeowners. Many times, it is something that you can do yourself. It can save you a great deal of expense. You may notice that you have a leak at your main shut-off valve. This is not the time to panic. Does water enter your home through galvanized iron pipe? Here are some tips for replacing the valve.
Your main valve does not last forever. Eventually it needs replacing. The first thing to do is shut the water off at the meter. This is usually a simple procedure.
Your meter may have a special valve. This requires a water meter wrench. The water company will come out and shut your water off. However, they will probably charge you. It is cheaper and easier to buy a meter wrench. Your local hardware store should have one for under ten dollars. Store your meter wrench in a easy access location. This will make it simple to find in an emergency.
Once the water is off, you can remove the old valve. You may require one or two pipe wrenches. These are a good investment for any home owner. You may also need to remove a pipe union. These are not difficult to figure out. It is best to take the old valve with you to the store. This will insure that you get the right one.
Do not forget Teflon tape. This is used to seal the threads. It helps prevent drips. It comes in a small, white roll. It is not sticky. It will stick to threads when you wrap it around them. Make sure that you wrap the tape in a clockwise direction. Otherwise, it will come off when you put the valve on.
Are all of the fittings tight? Do not tighten them too much. It is better to have a drip, than a broken valve. Sometimes you may have slight dripping. It may be best to wait a day or so. These drips will often resolve on their own. The water deposits will often form a seal.
Final thoughts
