Discuss Automatic Bypass Valve .. CLARIFICATION in the Plumbing Jobs | The Job-board area at PlumbersForums.net
Why would you need a room stat when you could replace it with a trv,s?. For example in my house I have trv's in all my rooms and I operate the heating from my programmer. I also have an automatic bypass before the motorized valves, so when all trv's are satisfied the pressure rises then automatic bypass kicks in and protects the circulator (pump). Also the other reason why the automatic bypass is a good practice is incase the motorize valves close shut from ware and tear and the boiler is still on the flow will buildup and automatic bypass comes into action.
i am nearly finished my 1st year plumbing apprenticeship so be nice.
