Attic Water Tank Overflow

That mysterious pipe is the overflow from the cold water header tank also called a cistern in your attic.

Attic water tank overflow.

The water level in a tank is too high so it is running out the overflow. If you have 2 tanks sometimes its as handy to change both if you re not sure which it is you can bend the ballvalve arm down a bit more as someone suggested but if its dripping often then this is only a temporary thing as it will eventually overflow again. I have an open vented system with a hot water pump stuart turner monsoon twin 3 fitted. With this type of valve the brass stem is bent downwards carefully to adjust the water level.

Looking for some advice. The tank in the attic has been trickling out of the overflow for a few weeks now. The water feed into the tank isn t switching off. The thermostat was broken in the emersion heater the electric hot water heating tank.

Have already changed the valve and float in the attic. In case if you were wondering these temperature pressure relief valve s too have an age limit when it comes to both productivity and efficiency. If this leak is very recent then the ball valve needs a new washer as the tank is overfilling. Go into the loft and take the lid off each tank.

That then caused a constant overflow from the pipe coming out from just below the eaves of the house. If the tank overfills excess water flows safely via the overflow to the outdoors. Tested it fine know it shuts off the feed that way. Take the lid off each tank and check how high the water level is in each one.

Look inside the tank. Set it very low but water is above the float. What could cause this hot water tank overflow pipe dripping issue. If you can see water constantly running or dripping from the water feed try checking the float valve isn t stuck as described in step 2 above.

If your cold water feed and expansion tank overflow pipe is leaking there are two possible causes. This caused the ovrheating water to expand into the expansion tank and then on into the large water tank in the attic. The tank will either be your cold water header tank or the flow and expansion tank for the heating system and the valve is a type 1. This water heater leaking issue mainly happens when the valve has surpassed its productive age period.

There are normally two but can be virtually any number depending on the size and type of system you have. If you re not doing it yourself and are waiting on a plumber and if its dripping often sometimes people would leave the cold tap in the bath running ever so slightly with the plug out obviously so the tank doesn t overflow.
