Internal plastic pipes

[Lynda W]

Hello
Please could I have some advice.
I recently had an new air source pump and hot water tank system installed. The pipes to the radiators are copper. However, there is plastic pipes to the taps for hot and cold water. I have found a leak in the connection of a plastic pipe.
First question is are plastic pipes that go to the hot and cold water pipes suitable to be used with air source pumps. I had my hot and cold water tanks in the loft before. They have been drained and are not in use any more. I have noticed that the pressure from my taps is much better now.
Second question, are spare parts for these internal plastic pipes still available. The plumbers I have had working in my house recently have never seen plastic pipes and don't know how to fix the problem.
Any advice would be gratefully received.
Thanks Lynda

If you’re in the U.K. then yes, plastic pipes and fittings are still available. Regards heat pumps and plastic pipes I wouldn’t know as I haven’t worked with heat pumps before. Can you post a photo of the pipe/fitting so we can advise you better?

Nothing wrong with plastic pipes for the hots and colds unless you've got hot water recirculation (for some manufacturers)
