The ball valve controls the flow

Nov 16, 2012

Many water heaters come with a drain valve that has a cone shaped handle. They spell trouble. Other makers of water heaters have a plastic faucet type drain valve. This type of drain valve is prone to breaks and leaks. The better types are the brass hose bibb, not unlike the average garden hose bibb. Even better would be brass ball valve. This type of drain valve would have a lever that can either be open or shut. The brass ball valve allows the most effective flushing of the water heater.

The ball valve controls the flow and temperature of the water by using a steel ball. The ball valves are washerless and easy to maintain because of this. Replacing a ball valve is readily affordable and easy to do.

Plastic cone valves and plastic faucet valves drip, freeze inside, and clog with sediment the easiest. Plastic threads are very easy to cross when you wish to attach a garden hose to the drain valve. Even after opening a plastic valve one time, using it and closing it back up, the valve may drip. To remove the plastic cone valve, unscrew it from the water heater by turning it counterclockwise while pulling it out. Six turns will probably be sufficient. Then turn clockwise and keep pulling. radiator valves Wrap teflon tape around the protruding nipple. Now install the brass ball valve. In order to avoid being sprayed with water while installing the new drain valve, first cut off the water supply at the cold water inlet near the top of the water heater. It is the pipe on the right side as you are facing it. Now open a hot water tap somewhere inside the house; any sink will do. Make sure the hot water tap is closed once water stops flowing through. That'll keep any air from entering the lines.This relieves pressure off the lines and will allow the drain valve to be replaced without emptying the water heater. Make sure nobody is using any water while you are replacing the drain valve. Also turn the gas to pilot or pull the electrical plug if electric.
