Dodgy cylinder??

[Nozzle]

Not bought many hot water cylinders before, so is it normal for the fittings to be so out of whack?
Also of the 5 compression fittings 3 won’t take a 22mm pipe, should I get a refund on this or let the manufacturer “fix” it???

I would be very wary about pressuring any cylinder that has creases and dents in the vessel. Perhaps if it's "only gravity feed" then fair dos, but nothing appoaching mains water pressure.

3/4" female to 22mm compression fitting, then the pipe will fit into that no bother.

I get you… essentially put another compression fitting on the end!

Yep 2ish meter head gravity fed, but like you say… I don’t trust it anymore, certainly not to last the 20years of the previous one…
