I'm Terry with Towers Murray Plumbing, here to show you how to repair your water intake assembly. When repairing the water intake assembly, also known as the fill valve or ballcock assembly, the first thing you'll want to do is empty the tank, simply turn the water off below, lift your handle up and hold it for a few seconds until the water drains. Now you may need to use a rag or a sponge to remove the rest of the water. You'll need a pair of pliers, disconnect the water supply line, then the locknut. Once you've removed the locknut, the assembly itself simply pulls out, take it down and match it up, get yourself a new water assembly, water fill assembly or fill valve, put a new washer on the end and you can reinstall this. Slide it through the toilet, lock the nut down. At this time you'll want to check that supply line, make sure that it's got good seals in it still. If everything looks good, you can reinstall that. If not, get a replacement while you're at the store. Now you can turn the water back on and check for any leaks, and again, I'm Terry with Towers Murray Plumbing, and we've just shown you how to repair the water intake assembly.
