Plumbing advice please

Hi we have just had some rad's and other hot and cold water pipes extended.
Plastic pipe has been used and speed fit conectors used on both the plastic to copper and copper to copper pipe is this correct or should the copper to copper be soldered?

Thanks Niall

Plastic can go onto copper for hot & cold water supply (I dont know if you can use it for radiator feeds & returns).

Copper to copper is always best soldered but you can (& have to) use other joints on hot & cold water & where they enter valves on rads it isnt soldered.

Thanks for that i will get the plumber to soldered the copper pipes now.
Thanks again Niall

You may have to pay extra for it. Soldering is more time consuming & it sounds as though your are also asking him to redo work he has already done (which in plumbing terms his work maybe acceptable).

Pushfit connectors can be used for copper to copper, plastic to copper or plastic to plastic.

IMHO they look ugly and would always use solder joints where they are visible.

All the joints are below floorboards or paneling

I am not sure why the op seems to think that he knows better than the plumber. There is absolutely no reason why push fit and compression fittings should not be perfectly satisfactory. I agree that they are not a very neat solution to the problem, but as the op states, they are all hidden anyway. Getting the job redone would be a very good way to get right up someone's nose I should think. Also a good way to get a much larger bill as well.

I dont trust push fit
cant the work lose or something IF they did get knocked or something?

Based on personal experience, I would say plastic pipe and pushfit are more trustworthy.

Over the past 12 years I've changed much of my pipework to plastic and added new parts. Never had a leak on any plastic parts.

On the otherhand, I've had 3 leaks on copper, one of which was a soldered joint which hadn't leaked in the 8 years after it was done.

4 of our neighbours have had 2 or more leaks on copper pipework in the last 5 years.

Give me plastic anyday..... (with pipe stifeners of course).

Any joint would be subject to a risk of leaking if knocked hard enough. Had numerous copper compression joints leak after a bash from the hoover or the kids have wacked the thermastat on the rad.

Most push fit components have a locking ring, so that they will not come loose, provided the ring is done up during the installation.

How can they get knocked if they're all under floorboards or behind panelling?
