There is a hot water tank at work and it keeps pouring out water vua the overflow pipe. I have moved the ballcock but the problem still happens. Could anyone help me. Thank you for reading. Dave

Have you replaced the pressure relief valve yet?

Water heaters do not have ballcocks so what are we talking about here? Fr and I both think you might betalking about a water heater but they also have no overflow tube but do have a T&P valve on the side near the top. Tell us more about what your tank looks like and how it functions.

You posted this question twice and its very hard to tell what fixture you are describing. Is this a toilet tank or a water heater?

I'm going to attempt to translate here. We have a hot water heater. I think "ballcock" translates to Pressure and temperature valve. So we take it from here. Chuck asked about a Pressure Regulating Valve. I don't know how he knew that you had one but do you? If so you need to install a expansion tank, (see image) on the heaters cold water supply. The T & P valve is leaking because the water has no place to expand to as it heats. The expansion tank provides a place for the water to expand in. Good luck, Tom

Its me again. OK the water tank has a ball floating on top of the water. That's what I meant by a ballcock. Obviously I have no clue what I'm talking about. There I a pipe also near the top that allows water to come out if it gets to full which leads outside. That is what I called the overflow pipe. So I move the ball so the tank wouldn't fill up as much andwhen it get to a certain point the water cuts off from the pipe attached to the ball. Am I making any sense here? But it keeps filling up and making water come out of the"overflow pipe" please help me

It really sounds like you are talking about a toilet tank, right? I think one of your original pots which has now been combined said something about hot water but maybe not. If it's a toilet tank ballcock then the height of the ball is adjustible. I thought you said this was at work, is that correct? Does your employer allow/want you to be working on this, if so we can help you adjust the float.

Dave! Right now !!! , Tell us whether you're referring to, a hot water heater?: A toilet tank? **OR** (as I'm begaining to suppect,) a outside water storage tank or a aeration tank? In six posts you have us spinning our wheels attempting to find out exactly what your problem is. Time to "fess up" and give us a explanation we can work with. Regards, Tom

It's a hot water tank in the loft space at work. I adjusted the ball floatinging thingy. But it still over flows. I went into work yesterday and the room below it was a bit wet. Oops. I think that might have been me. They got a plunber out to fix it. He said it needed a new valve. But its still leaking. The wit. Has this painted a better picture?

Hell no! I'm more confused then ever. Are you located in the U.S? You're describing a open hot water tank? Some sort of a storage tank that's being supplied by a water heater? The heat lost due to a open hot water storage tank makes this set up unbelievable. Something's not right here. A water storage tank I can understand but I can't buy a open HOT WATER storage tank. What purpose would such a tank serve? I'm missing something here. What is it? Regards, Tom

I'm confused too lol. Right its in the loft space. It's a water tank. It has a loose lid on top that I took off. It wasn't fastened or any thing. I put my hand in and it was hot. I adjusted the ball. I'm in the uk. In the west midlands. It does look quite old. The tank not west midlands although that is as well

Thank you Dave, Let me show you how to adjust the tank level. Grasp the rod just ahead of the float ball,(see imag, do not grab the ball itself) with one hand and next to the ballcock with the other.
Bend the rod up to increase the tank level and down to decrerase the level. . Good luck, Tom
