Removing a couple of bricks

[StephenW]

I'm about to get quotes for replacing a floor-standing CH boiler in the kitchen with a wall mounted one in the garage. (Sounds like a plumbing question coming up - but it's not!) Currently the 4 water pipes (two 22mm and two 28mm) from the boiler go up the surface of the kitchen wall into the floorspace above which is under the bathroom floor.
I want to knock a hole through from under the bathroom floor to the adjacent garage for the new pipe run. I believe it to be a normal cavity brick built wall (above the garage it is the outside wall but because of the split level the bathroom floor level is about 800mm down from the garage roof).
If I was to remove say two horizontally adjacent bricks what sort of support, if any, will it need in its place? Do they do a metal framework to line the hole or should I put a half brick in the centre, or what? How would this normally be tackled? Thanks.

Precast concrete lintel over the 450mm wide hole your making each side of the cavity wall..

Any decent plumber should be able to core drill the four holes.

Sounds like British Gas have disturbed your leisure period Nige.

Thanks chaps. I'll see what the quoting plumbers say. Several drilled holes would probably be easier. But if I was to remove two bricks I should first remove the three directly above them and insert a lintel (or two if I'm only removing one brick).
