Roof Water Tank Overflow

If its the big tank that feeds your hot water cylinder it might be that the water level is too high in tank.

Roof water tank overflow.

If the gutter is tilting away from your house it could be causing an overflow particularly during heavy storms. 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 the valve is on the side of the tank this should be about 5 gallons. Same goes for lack of pitch which causes the water to gather in one spot rather than flowing toward an exit.

A constant drip in your tpr valve is an indication we must know about. If you find water pouring or dripping from a pipe pointing out of the building or from eaves of roof then a cold water tank is overflowing. The water feed into the tank isn t switching off. A failure in the tpr valve could lead to a situation where the tank could even blast.

Look inside the tank. If water continuous running out of hot water heater overflow and water heater overflow pipe gushing you have to change drain valve. This may be the smaller feed expansion cistern putting water into central heating circuit or it may be the storage cistern for cold water supplying the cold water bathroom taps and hot water cylinder. Gravity feed rainwater from a header tank and pressure supply from a bore.

The water leaking from the drain valve is one the signs of a faulty water heater or a valve. The pitch of gutter heading towards a downspout can also cause overflow if it s too steep. When rain water was low we switched over to the bore supply which caused water to dribble out of the roof top hot water cylinder overflow requiring an adjustment to the ajax valve every time we changed water systems. So when the water heats up and expands the tank overflows.

If your cold water feed and expansion tank overflow pipe is leaking there are two possible causes. Turn on a hot water faucet somewhere in the house to a dribble to prevent a vacuum from forming inside your hot water tank. In my last house i had two water supply systems. So this release of its pressure causes your hot water tank overflow pipe dripping towards the floor where the hot water heater is placed.

You need to check the ball on the valve isn t full of water or hasn t slipped down the arm of the valve allowing the water level to get too high in the tank.
