Running antifreeze through your water heater every winter wastes gallons of antifreeze that never actually need to touch the tank. This by-pass kit reroutes the winterizing antifreeze around a 6-gallon water heater instead of through it.
It's designed for seasonal installation, so you can plumb it into your water heater lines once and switch it between by-pass and normal operation each fall and spring.
A one-time install that pays for itself in antifreeze savings every winterizing season.
