With the john guest and Hep 2o systems, you must always use the pipe inserts to be inserted toboth ends of any pipe. This ensures that the pipe always keeps its perfectly round shape which will then ensure a best sealed fit. Don’t worry as this can take way more pressure than you would ever think- up to around 50 bar, where as in a typical house you would see between 1 and 10 bar.
Where ever you lay this pipe along with its joints, you must make sure there is nothing pressing on it. For example, if you lay it under floor, you would spade drill through the joists which would give the pipe and joints plenty of clearance from the floor boards.
- Do not reuse old plastic plumbing as you don’t know what the last guy did.
- Do not use pipe which is scratched as this could affect the seal guarantee
- Do not use when you need to fit a thermostatic or electric shower connection (better practice using copper)
- Do not plaster or cement into walls or floors
- Plastic pipe can be used with brass (copper) fittings
- Just use new clean parts and don’t kink the pipe
