After the umpteenth time our downstairs water supply has frozen I'm planning to replumb and surface mount everything above FFL.
It's a house on stilts in the Cairngorms, timber floor sections with poorly fitted draughty ply undersides, poorly insulated pipes (can anyone advise if it is building regs to use 15/25 Thermaflex within an unheated floor? Ours has 15/13 thrown loosely at it) and the pipes are within the floor...
Hopeless situation, and a cost cutting exercise with as disastrous results as them using cheap wire in the "Towering Inferno"....
So, given that everything is quite accessible above FL, I'm planing to cut into the Hot where it comes down from above and branch it to the shower/sink/kitchen sink. At present the 25mm Cold supply pipe rises into the cavity behind the cistern then branches off to supply upstairs and disappears the other way below the floor. I'll cut it here and branch it out too, including the toilet. All pipes where contained in walls above the floor will be immaculately insulated and the cavity filled with insulation to boot. to stop draughts. Ideallly I want to surface mount them and keep out of the walls. The toilet sink will need this anyway not putting anythng in external walls.
So, after a long winded intro can anyone advise should I use compression or pushfit connections? I'm not a plumber(stonemason JOAT) but have done my own showers ok before, but I'd rather use pushfit this time to speed things up and keep it simple- if so which brand is superior?
I'm pushing to get the builder/seller/architect to bear this cost but they are useless and they will drag their heels rather than admit they have cocked up. They tried boxng the area off in the summer but I knew it wouldn't work the draughts are everywhere supercooling the pipes.
The builder is NHBC registered does this mean I could claim off them regardless? The workmanship is poor as is the design!!
