Hot water in the cold system
Posted by John Scott on December 20, 2003 at 07:59:39:
This problem is in a a new rural house. water is pumped from the lake and filtered etc. It runs 3/4" copper out of filter to a tee 1/2" to water heater and cold feed to house. When cold taps are turned on hot water comes out all of them same with a tolet flush. The lines are not crossed so cold is cold line and hot is hot. Could it be some how a problem with the pipe size creating a syphon from the hot water tank or a cross bleed in a faucet? or something else Help!!!!
