Mixing up plastic pipe brands



Flo plast is selling 25m of 15mm for £18 odd at screwfix.

I only need to mess around with my hot water supply under the sink due to a new section of kitchen units being added, so the sink will move.

Does it matter if i use this pipe along with john guest fittings as all the fitting are JG and using copper. However i want to use a good length of plastic so i can miss out a few joints i have found.

I understand mixing fitting on heating is not a good idea, but surley hot and cold water will be ok.

it should be ok, I've done it before for temporary stuff, the pipes are all the same size at the end of the day. but the manufacturers wont support it, therefore no guarantee.
Most tradesmen wouldn't do it as its simply not worth the hassle if something goes wrong, but as a diyer I'd say no problem.
