I assume "up and over" means that instead of knocking down your house to get to the leak ... you just install a new pipe to bypass the leak.

Before you spend a lot of money ... Ask them how they  know you have a leak?

They mean bring a new pipe into the building from outside, possible a kitchen or wc whichever is best.

pipe has to be 750mm from the outside to where it comes out the floor.

Ask the water company about a mole which bores under the building and can be connected anywhere on the ground floor by digging a single hole.

I would also consider renewing all the pipe back to the stopcock in the pavement.

Thereforethe existing pipework will be abandoned.
Your bathroom being fed from the water main probably does not comply with regs. Bathrooms are normally fed from the storage tank to avoid contaminating the mains water. So you will probably have to re-feed the bathroom from the attic storage tank. [/quote]


Talking of amusing bollocks

Is this a joke?  ???

Well he obviously knows f*ck all about plumbing  

Thank god for Norwich Union then!

My advice was absolutely correct for an existing installation, check valves have only recently been introduced.
Also the storage system method is still preferred by the water authorities.
Mains fed Bathrooms are a cheap poor quality installation that can comply with the water regs, but do not give any storage capacity in the event of mains water failure.

sparxxxx(correct me if im wrong PLUMBERS) but storage tanks are there to releve the strain on the water supply surely, i.e. in a bathroom you might run a bath, flush the loo and run hot water all at the same time, = poor flow rate

and if every house was fed with say 28mm pipe to compensate imagine the strain on the supply structure when the whole street goes off to do the same thing after corry!
