water pressure question (backflow?)
replies to my mixer shower fitting questions has prompted more.
Currently my bath has a mixer tap, hot from tank, cold from mains. If I turn the cold on full (with the hot still on) it runs cold (obviously) but the hot then takes a good while to come back, could this be due to high pressure cold forcing the hot back to the tank, and is this a problem? I was planning to pipe cold from the header tank, is there any alternative so i can use the mains feed, such as pressure equalising valves (such as the ones Screwfix sell), non-return valves etc? Thanks for all help |
