Is My F&E Tank Too Full?

[adzyp]

Noticed a small brown batch on the ceiling above the bathroom this morning so went up into the loft and saw that the F&E overflow pipe was dripping....loose compression coupling, sorted now hopefully.

But whilst up there I was taking a look at the tank, never had one before. Pictures show how full it is when cold. As you can see, the water level is level with the bottom of the overflow on the right so can only assume this will rise when the heating is on (have just turned heating on so will check again in a bit)

Should the water level be much lower? Is there an easy adjustment to do this?

Thanks

The F&E cistern only needs a few inches of water in it. The level of water can be adjusted by bending the float arm down ,the lower the float is ,the resulting water level is lower.
You would need to drain out some water first of course. And do it with system cold. 3 inches of water is enough.

It's possible the ball valve is leaking. Worth checking and renew if necessary, preferably with a diaphragm type.

Ok thanks, ill keep an eye on it.

Ive now lowered it and water is much lower. What would be signs to look for now if valve is leaking? Water rising again?

Do you have a link to the type you suggest, may just change anyway if its easy enough to do

The valve will drip a little, immediately after it has topped the level up, but it should not continue to drip beyond that.

Dripping as Harry said, see it quicker than level rising

Attached. Diaphragm type less prone to sticking due to scale.
