First Fix Plumbing - can I do it myself?
Discussion
After receiving a couple of eye watering quotes for installing 6 rads, a combi boiler (supplied by me) and first fixing DHW to a kitchen and a bathroom, I'm starting to look into hanging the rads and putting in the pipework myself, and then have a plumber in to connect the final metre in copper to the external boiler and connect it up to the oil tank.
I've turned my hand to most trades, so not shy of DIY, but never have I done anything on the heating side of plumbing.
Anyway enough of the background, this is my proposed heating layout:
Am I along the right lines or am I miles out? Would you change anything?
One thing that I'm not sure about is if the vertical F&R pipes up into the loft bedroom needs to be in 22mm or can be reduced to 15mm at bathroom level?
Oh and barrier pipe: Polypipe/Hep2O/Speedfit - are they all pretty much the same?
More questions will be forthcoming about pressure testing/thermostats etc.

Finally started on this and so far so good. Told you that there would be questions, so...
I'm going to pressure test once complete. Going to pump it up to 10 bar for 2 min, then 2bar for 10 mins (and probably leave it over night).
Is it best to pressure test with the rads connected or should I cap off at the tails before the trv?

Thanks chaps.
Good to know about the air side of things. Is wet testing easy enough to do? I assume there is a machine that I need to hire to do this?
We're just on the heating circuit at the moment, but so far so good. A few things I hadn't anticipated, but nothing that I wasn't going to do at a later date.
It did, however, take half a day to clear the void in the ceiling above the GF staircase to run the 2 x 22mm pipes across. Looks like a previous builder used this area as a skip. Pulled no end of bricks and rubble from there. Had to remove it all through a brick and half size hole in the wall to either side of the staircase. The amount removed would have easily filled a dustbin - surprised it didn't make the ceiling collapse!
