Must have water leak - Fluidmaster cistern fittings?

[domcastro]

Hi
I just received my metered water bill and it is £130 more than usual for
6 months worth - there has been no change in usage. If I turn my stopcock off, the meter doesn't move so I know it's a problem with my house and not the pipe. If nothing is currently using water in my house (no w/machine on, no heating, toilets nice and full) the meter is still going around. I have no obvious leak anywhere including the loft, no water smells etc. I think it may be the toilet. It's one of those new ones that overflows into the loo instead of outside (Fluidmaster). I've just noticed that water is constantly trickling from the cistern into the bowl. Could this be it? 6 months worth of toilet trickle?

1. Could it be the toilet?
2. If it is the toilet, can anyone direct me to Fluidmaster user manual?
3. If it's not the toilet, what's the next step to take in the investigation?

Many thanks

if the toilet is constantly overflowing in to the pan then the fill valve needs adjusting or its not shutting properly.

Or the fluidmaster isn't seating properly.

Turn the inside stopcock off and check if the meter is still going round.

And yes you can waste that much water if the wc is permanently leaking, and the worse is yet to come, your waste water bill will also be inflated.

no jay but if it goes in it comes out

thats how they set the sewage charges

Is waste water metered then

Don't be daft

A percentage of the water meter reading is used to calculate the waste water, so the more water you use the higher the sewage bill will be.
