I suspect the answer here will be "don't be stupid", but I thought I'd ask to see if there's a feasible solution.
I'm installing my own rads and pipework for a central heating system, but I'm doing it piece meal over time, whilst also decorating/renovating my house.
I'm planning to purchase a Rothenberger wet pressure testing pump so I can pressurise small sections of pipework as per the part L regs to ensure there are no leaks. On top of this, I'm going to try and be careful and ensure that only bent pipes are buried into the wall (not joints) where the tails of the rads disappear into the the wall and reappear under the floor boards.
My question: could I install the radiators with some pipework chased into the wall, then make good the plaster so I can decorate, before the boiler is installed and pressurised?
The main area is the bathroom, where I'd like to tile the floor. I'd have two 22m copper pipes coming from the 1st bedroom, through to the bathroom, and to the 2nd bedroom, which would then be t-d off for the towel rad. Joints would be soldered, and then I"d pressurise with the Rothenberger tester to test for leaks. Could I then go ahead and make good the walls and proceed with tiling the bathroom floor?
... or is this just asking for trouble? I'd only be doing this in the bathroom and the the plaster on the walls, but when the central heating is installed I'd be able to lift floorboards in all other rooms except the bathroom.
As much as I'd like to just get the job done in a weekend, I don't actually have the funds to get the boiler connected right now, and as temperatures are going to increase over the next few weeks, I'd rather get the place presentable and tackle the central heating a bit later. But if possible I'd prefer to to at least lay the ground work to avoid larger upheaval later on.
What do you think?
