Toilet Service and Repair Instructions. Most practices of repairing toilets are quick easy do-it-yourself projects. The real challenge of repairing a toilet frequently is finding the part causing the toilets problem.
A homes toilet should have its own shut-off valve placed somewhere near the fixture. Usually, its a white-plated compression fitting with an round knob. So find that before working on toilet
A toilet tank’s water level should fill to about 1/3″ to 1/4″ below the overflow tube. Adjusted the float arm screw gently to adjust the water level; down to reduce the level or up to increase it.
If the screw is hard to turn or needs to be bent a lot, unscrew it first to avoid damaging the fill valve assembly. Also, some models have an adjusting screw on the ball valve to regulate the tanks water level.
Check that the flapper (or round disk) seats correctly. Flush the toilet a couple times and adjust the toilets flapper until it seats correctly . Adjusting the chain connecting to the handle rod if to much slack in chain if needed.
If the toilet flapper seats correctly, but doesn’t stop leaking, clean any gunk or buildup around the flappers opening. If the toilet flapper is still leaking water , simple replace it with a new one.
A faulty fill valve (the assembly attached to the float ) may fill the tank and cause water to run periodically down the overflow tube. Always shut off the water supply valve off before removing the fill valve.
Sometimes, the fill valve seals can be repaired and the leak will stop. But finding the source and fixing the problem may not be worth the trouble.
It’s often wiser to buy the whole new fill vale assembly so you’re sure the leak will be repaired. Or upgrade to an fluid master pro which seems to operate and adjust a little easier than the standard arm-type float.
