why does my outside overflow pipe leak constantly?

Question

It's not near my upstairs bathroom, just on the outside of my house. It's like a waterfall out there!

Favourite answer

Knowing what pipe is leaking would help. For instance: The water heater has a safety valve. If the water pressure and temperature get too high, the valve will allow water to leak out, relieving pressure to prevent a steam explosion.

Outside overflow pipe? Why is it outside? Is it something inside that is designed to leak outside?

Well, as to the answer to this question, something must be overflowing. Either that or a valve is not closing properly. Water heater safety valves sometimes leak just because they get old.

You need to determine the source of the leak in order to fix it. If you are not able to handle plumbing issues, you should call a licensed plumber.

Sorry if this doesn't answer your question, there isn't much information for anyone here to be able to help you with this.

Ha ha, my tightwad Hungarian neighbors had this and left the house one winter for a couple of weeks; when they got back there was a huge ice fall leaning against the outside of the house. It made a mess of the lawn when it thawed and fell over.

You have a leaking inlet valve on one of the tanks in your attic. This is probably the most common and simplest plumbing problem any householder will face. The tank is slowly over-filling and the overflow is doing the job it was put there for. Flushing the toilet shouldn't make any difference but most other water use should.

Check the toilet cistern and the water tank also the central heating header tank the last two will be in the roof space. One of these needs attention as in new washer on the ball **** which is supposed to cut the water supply when the tank is full. Same on the cistern when it is full the supply should stop. One of these should be the problem.

It could possible be the drain line for the condensation from your furnace. If that's what it is, it's very necessary because it keep water from forming inside your home.
