overflow pipe problem

[afc123red]

hi can anyone help please in the attic of the piub there are 2 water tanks a bigger one above a smaller one the top one is full of water and the bottom one is bone dry,there ids a ballcock in each and at the moment the overflow pipe outside is continually flowing water..shoul the bottom tank also have water in it and then when that one fills it should ythen go to the overflow pipe ..help please

Conventionally, the large tank supplies the domestic hot water, and the smaller tank is a header cistern for the central heating.
The large one should be full and the smaller one should have around 4" of water in it.
It sounds like the ball valve for the larger tank is allowing water to pass when it shouldn't!
Please post a pic so we can identify things better.

And the bottom one sounds like it's doing the opposite, as it's bone dry.
Cold and rusty rads aplenty.

replace both ball valves. The large tank provides gravity-fed potable water for the hot water cylinder and taps. The ball valve that fills it has seized open, causing it to overflow. The small tank is designed to fill up the radiators and heating with water (and should be full, with inhibitor also)-maybe the valve supplying the small tank is turned off?

Alternatively the hot water cylinder is guffed.

Would hardly call the water from a cold water cistern potable - but then each to his own .

guffed? Is that a technical term? lol

 

[Dan Robinson]

It is indeed a very technical term.

For the laymen... it equates to the cylinder being fooked .

Guffed, cream crackered, cattle trucked all mean the same thing.....time to spend money!

lol, only if the boiler header is higher than the cold storage tank and the coil has corroded in the hot water cylinder, (the cold tank is full of warm brown murky water) or someone converted the boiler loop to a pressurized one with expansion vessel and filler and left the header up there doing nothing.

OP, is your cold tap water warm, brown and murky? If not, just replace the ball valve (s)

 

[Dan Robinson]

Just re-re-read the OP's first sentence. Cylinder is unlikely to be goosed...
