Is this work acceptable (pics)? Central heating system

plastic is great, im doing a new build plastic install this week. The problem with it is so called plumbers find it easy to fit compared to copper, so there tends to be alot more poor plastic installs compared to copper. It takes a skilled plumber to install both plastic and copper systems correctly, both have different advantages and disadvantages but a poor install is normally the result of a poor trademan.

You need a different builder ASAP. I hope you haven't been paying him cash in up front payments, I really do.

I have seen worse,as long as there is no actual directional stress on the joints all should be fine.
