John Guest fittings

On the John Guest products and watching the video, they do layflat plastic water pipe which make it easier to feed under the floorboards or through joists. According to http://www.bhl.co.uk live chat, it's only suitable for underfloor heating I'm going to fit a water softener and I want to by-pass so the hard water is on the kitchen tap and outside garden tap only, would be easier if I can use the layflat pipe type under the floorboards. Have got the MDPE Blue Waterpipe 20mm which need a Tee pipe - 20 x 15 x 20mm. What plastic flex water pipe I can use and connect a Tee piece to MDPE 20mm blue pipe?

The reason for the hard water to garden is that some plants don't like soft water and also cannot use soften water in hot tub

look in technical. local merchant(plumbase) only sell this now. so if it were'nt ok for hot and cold services etc it would be pointless selling it. regards using it i still find it a bit springy. and not really the lay fat i thought it would be. still better than the old stuff which could be a nightmare.

Maybe im missing something but why not just use standard barrier pipe, 15mm isn't all that hard to work with even off 150m coils.

Speedfit do PEX (Cross-linked Polyethylene) and PB (Polybutylene) barrier pipes.
For some manufacturers PB is standard because that's all they do.
Speedfit's PB has less 'memory' than PEX, therefore lays better, not trying to spring back into a coil.

Dunno, thinking might not be too flexible under floorboards

Would I get away with using 10mm water pipe approximately 15m run just for kitchen cold feed tap and garden hose

It's flexible enough to work with.

10mm will work but will really drop the flow rate down and dosen't seem like a worthwhile comprimise as it will only make the job marginally easier
