Plastic pipe or copper

[Donkey_uk]

Hi, I want to install a salamander hot water pump to my hot water taps, from my tank in bedroom. I will install a new s flange, my question is can I install this with plastic pipes ie speed fit instead of copper

Yes, but the internal diameter of plastic is slightly smaller than copper. Unlikely to make much of a difference but best to point it out.

Also, don’t mess up your open vent arrangement.

That's perfect thsnk you, I thought that I could but just wanted to make sure.

Yes open vent at top of flange and the water coming from side of flange

Make sure you get the correct inserts for the plastic pipe.

Are they just the standard push in inserts or do I need specific ones

You need to get the inserts that match the brand of pipe/fittings. Don’t mix and match

Perfect, thank you for your help, much appreciated,

Oh should I also use an olive when connecting plastic pipe to copper flange, I I know I would put the inserts in however some people say use olive as well is this true

When you insert the plastic pipe into a compression fitting, you need to slide the nut on, then insert in and finally the olive.

The olive creates the seal. No need for paste or ptfe tape on plastic.

Buy a plastic pipe cutter to ensure all cuts are clean and straight.

Some warranties require a flange to be fitted, in some installations, regenerative pumps (for example, the Salamander CT range) do not necessarily need a flange, You should try copper pipe perfect fitting and durability!
