FAO a Plumber!

[MrFlibbles]

I've developed some irritating toilet habits.

When the loo is flushed, shortly afterwards there is a very loud bang bang bang as if the pipes are rattling.

What is the cause, and how can I fix it?

Cheers!

Ensure the pipes arnt leaking nearest your neighbours side of the property

Sounds like your pipes are rattling

IIRC, it's air in the pipes but I can't figure out why that would just start on it's own. Perhaps add some extra clamps if you have long pipe runs?

I am not a plumber and I could well be talking complete bollox.

We had that - high water pressure and a bobbing ball cock created huge 'hammer' effects. Hang a bulldog clip on the ball cock thing to damp the oscillation

Yep most likley the ball valve causing "water hammer"

Forget Teds bodge job and replace said valve just a few quid and 10 minutes work.

Whats a ball valve? Is it in the loo or the tank?

[parrot of doom]

You sure its not the pipes supplying the water for the cistern?

Might be best that you call a plumber!

There's lots of possible fixes for this:
Change the ball valve (in toilet cistern), Secure rattling pipework, Reduce mains water pressure, Fit a shock arrestor.

You can replace the conventional ball cock with a new plastic one. I did mine a while ago when the ball split the rest was rusty so replaced the lot. The new plastic one is quieter and faster filling, got mine at Homebase and was and easy fix. This was the first time I have had a go at a plumbing related job so cant be that hard.

The new bit will come with instructions but your best bet is get yourself a DIY manual as well for future reference.

So how do you stop musical bog-flushing pipes?
As it fills up the tank we get tinnitus stylee harmonics starting at jumbo jet engine noise levels and fading over about 10 mins to am I imagining it or has it actually stopped level which does my head in and wakes up the sprogs plus the frigging wife is pi**ing more often than a diabetic elephant.

Just found a new site (to me) how to change a stopcock

It's water hammer right enough caused by poorly secured pipes 'somewhere' in the property. Easiest fix is to fit one of the many equilibrium ballvaves on the market. 'Torbeck' probably easiest to find or the 'Fluidmaster'.
