Chasing Pipe into walls - the correct way

So I am getting a new boiler and central heating installed installed (with all new piping).

The building has solid concrete flooring and cavity walls

Some gas safe/plumbers have mentioned that they would like to chase the pipe into the wall..

However, I wanted to know that once the wall has been chased, what needs to be done to the pipe in order to protect it e.g. from corrosion, bursting etc

Does anyone know if the building regs have any information on this?

 

When I did it for some rads I just wrapped the pipes in masking tape. I think it's because cold pipes can collect condensation even through plaster and the alkalinity of the damp plaster can then attack the copper.

 

Can't you get plastic coated copper pipes now that are best of both? Solder them up, don't worry about corrosion.
Also heard some people saying they run the copper through a larger plastic pipe for protection.
All costs more than Denso tape though.

Denso for me, fitted properly will last forever

 

Interestingly, one of the plumbers mentioned that there preferred method would be to use plastic push fit style pipe..

The rationale being that

1. It's quicker to install
2. They are cheaper than copper
3. Unlike regular push fit fitting, this one cannot be simply pulled out. A key is required in order to open the fitting
4. He has been fitting these fittings for years and he has never had a call back once
5. 25 yr guarantee

Is anyone familiar with this fitting?

As it is plastic, I am assuming that it will be fine when chased into the wall and under the floor joists on the upper floors

Or should i stick with the tried and tested methods?

That's a great shout.. Thank you.

 

Plastic pipe is fine but dont have any fittings within the wall whether they need a tool to demount or not, if you want to use plastic buy a coil so you wont need to join it

 

yep, what Ian said. Make sure both ends are easily accessible if you need to replace a fitting.
I had a radiator connected up with plastic fittings, feel a bit uneasy about it but left easy access in the floorboards where the plastic joins the old copper pipes.
Ideally, pipes should start and finish at appliances / sinks / mains though where you can see them and check they aren't leaking.
