plastic plumbing - a quick "pipe, inserts & fittings" query

[jim]

In midst or reasonable sized extension of living accomodation including extensions to CH and H&C water.

Used 15mm Hep, 22mm Hep and some "toolstation" 22mm plastic (all barrier) - need some fittings to suit a few awkward connects from 22 to 15 (reducing tees) - they are avaiable in Speedfit but not Hep or Polyplumb -

QUESTION when joining 2 different makes of plastic pipe at a certain (possibly 3rd party brand) fitting - whose pipe inserts do you use - the pipe manufacturers? or the fitting manufacturers? or doesn't it matter? (and why please!)

thanks in advance

Jim

External diameters are the same so can be used with any manufacturer or even brass compression fittings.The internal dia. do vary slightly so you must match each pipes manufacturer with insert.

Are you sure ?

I have got loads of various reducing tees from Hepworth. Search their website.

is the only thing I hate about odd sized plastic joints. They are bloody expensive.

90 degrees- couldn't see on Hep20's website - speedfit in screwfix catalogue appears to have 'em...

In article , jim writes

Do 'em with compression fittings?

[Doctor Drivel]

Use a brass Conex compression joint, not a push-fit. Use the inserts for the particular pipe it joints to.

You should not mix types of plastic pipes in an installation.

Hi Jim

You need a Double End Reducing Tee

if the link works. There is no image for the 22x15 one on the Hep site I gave you earlier but is it there.

I personally would not want to join JG speedfit to Hep or PolyPlumb using plastic connections. Hep and PolyPlumb are interchangable IMHO and there should be no problems connecting them togther using each others plastic connectors.
