Review on Mudder Pieces Plastic Compatible Heaters by Reginald Pitt

Plugs are well made, pipe threads are easy to tighten. It is always recommended to use several wraps of teflon tape on the threads to ensure a good watertight seal and easy installation and removal. They can be reused multiple times as long as the head or threads are not damaged. SAFETY. Hot water can burn you! Be sure to let the water in the tank cool BEFORE you drain it! To speed up the process, you can turn off the heat and turn on the hot water faucet in the sink/shower to "flush" the remaining hot water in the tub. After cold water flows from the faucet, turn off the water supply and remove the drain plug from the water heater tank. You can speed up the emptying process by opening the safety valve. Don't forget to close it afterwards.
