Water & byelaw 30 kits

AdrianW2

In a traditional gravity fed system the feed & expansion header tank overflow is often run to the cold water tank. Is this system still recommended or should the overflow run to somewhere else, probably outside (I notice that byelaw 30 kits don't include a seal for the pipe)?

hi
ur ok it still should go in the tank their should be a round rubber washer in your bylaw 30 kit with a hole in it for the expansion pipe to go into after you have knocked out the hole for it in the top of the lid then if the expansion does blow off and the water reaches the overflow outlet it will just go out the 1 over flow the same as if the ball valve fails it will go out that one two there is no need for two overflow pipes on one tank same applys to ur heating tank as well if you have one of those
