Saved a bundle & worked like a charm
Releif valve on Bock hot water tank went bad. Local plumbing store had replacement cost @ $468.00. This one was the exact match to the one I was removing.

Great Service from SupplyHouse
This is a very expensive Watts P/T valve. It is well made and used with Bock oil-fired water heaters. But there really is no better place to purchase it than from SupplyHouse. It was not a stocked item, but these folks went the extra mile and got it delivered within days of my order. Thanks SupplyHouse..
PS: Make sure that you also buy a GALVANIZED steel 3" x 3/4" DIELECTRIC pipe nipple. Do NOT use a brass one because electroysis between brass and the steel will corrode (destroy) the steel fitting inside the water heater.
