So the missus is on a redecorating mission. She went out last weekend to buy paint and skirting/attractive and came back with new designer flat panel rads and chrome angled trv's.
The existing rad pipe work is all 10mm microbore and buried in the wall. The pipe work comes out of the wall on elbows into a 15mm straight valve with reducer. To make matters i will need to adjust the pipework to accommodate each of the new rads.
Yesterday I decided to make a start by replacing one of the smaller rads in the hall. I drained the system, knocked a hole in the plaster board and chopped the pipes. I then used JG speed fit parts (10>15mm reducer and 15mm elbows) to position the pipes as needed. I later discovered the JG connectors were slightly too bulky to fit between the internal breeze block wall and the plaster board. In the end i had to chisel a little a way from the internal wall so that i could push back the elbows/reducers enough for them to fit. What i expected to take an hour tops took me the best part of 4 hours.
I dont fancy having to repeat the above for the other 6 rads so i was think of using 10>15mm reducers and flexi-hoses with 15mm tap connectors? These should fit behind the wall without the need of chiselling. I know it probably not the more cost effective option but surely it would be quicker.
What do the pro's suggest? I'm sure there must be a better/simpler way to do this.
PS - the subfloor is concrete otherwise i'd have took the pipes under and backup through the floorboards.
