hi all, what is the 3 tee rule?
Discuss 3 tee rule anyone? in the Plumbing Jobs | The Job-board area at PlumbersForums.net
Couldn't remember the order aha so cheers! Need this for today!It's the order in which the bypass, cylinder return and heating return are connected. Running from the boiler back the connection order should be bypass, cylinder, heating. After the heating return the cylinder return and bypass should be teed in at right angles to prevent reverse circulation. It's a very simple rule but it's amazing how many people ignore it and then can't work out why the upstairs rads are hot in the summer.
