MDPE pipe and fittings, are all equal? What durable brands to buy?

[Leef]

Dear All,

Whenever possible I aim to buy the correct quality product the first time round. Plumbing labour and water damage is expensive, thus, very happy to pay quite a bit more for materials provided it is needed to ensure a lasting product over time.
Your advice will be much appreciated.

Are all makes similar, or, should I buy a specific make or brand for:
a. Pipe, MDPE {32mm in this case I need < 25m}
Toolstation +- £23, Bes +- £34, jtmplumbing +- £40.

b. Stop cocks.
I intend to buy Plasson. compression stopcocks.
Are these good and will this last a great many years?

c. Fittings, reducers and pipe liners.
These I find most confusing as the cost vary hugely.
Should one buy the most expensive options?

Examples I consider:
i. Pipe liners.
John Gues+- £0.53, Flowpast +- £1.20, Polyfast £0.95, Toolstation liner £0.57

ii. Fittings and reducers.
Massive price differences here.
# bes.co.uk two options, say 32=>25mm reducer: Flopast £5.04 vs Polyfast £19.48
# Toolstation £4.17
# JTMpluming, Plasson £16.78

Thank you,

Either of the above will do the job, but I would use philmac given a choice all I would say is dont mix brands stick with one manufacturer and use all brass stopcocks unless external in a underground chamber. Kop

For mdpe fittings I only use Plasson, pipe from local merchants too but I’m not sure what make it is. Personally I’d not be so worried about pipe as long as it’s stamped up to all BS etc.

i use a mix plasson for mdpe connections

and phil for transion couplings
