Dodgy cylinder??

Grun · 25 Oct 2022

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???

You could always pull a slight bend on the pipe so it appears straight

Grun · 25 Oct 2022

Thanks… yes, I can bend a bit of pipe, but is it normal that I should have to? Do all tanks come like this or have I got a duff one?

Just for future reference whos cylinder is it

Grun · 25 Oct 2022

The green, and flat top should be a bit of a give away, but I’d rather not say just yet as I’m still trying to get their help, I don’t want the p**ed of at me!

Well unless they are monitoring forum sites and know you as Grun I think name and shame is the order of the day plus others may be able to say they have or had not the same issue with this supplier but each to their own idiosyncrasies

This one, the bit that’s attached to the cylinder is to small, see the lip after the olive. I guess they forgot to expand it to the right size during manufacturing.

It looks to me like the olive is not sitting square in the fitting. Have you tried inserting the pipe without the nut and olive in place. Very unusual for the pipe not to fit. I don't think I've ever seen it. If it won't fit, you'll need to return for replacement as its useless.

Yup +1, take the compression nut and olive off the fitting, put them over the pipe and then see if the pipe then fits in.

Use cylinder unions.
The pipe won't fit direct to the cylinder tappings.

Ah ok, just took another look of the pic .....

OP, take the nut and olive off that pipe and let us see the tapping in the cylinder. If they are brass compression tappings then they would usually be wide enough to accept a 22mm pipe, as the top and bottom pipe seem to be.

You may find you need to fit a 3/4" female to 22mm compression. if you take the 22mm nut and olive off and attach the female end with tape/cord/thread/gunk/whatever. That'll give you the correct compression end to attach a pipe.

Strange why it's not either just a pipe tail or just a plastic capped threaded tapping.

Thanks for all the responses, when I ordered the cyl I went for the 22mm compression option “for convenience” (yes, a mistake i know now)
So here are some more pics, two of the fittings are fine and the pipe pushes home up to the black mark, the others won’t push in at all…
I think I’m getting the general opinion that this is not something I can fix in the field and it will have to go back.

Madrab · 26 Oct 2022

Yup, if the pipe won't fit then they aren't right. As suggested though, they would take a 3/4" female to 22mm compression fitting, then the pipe will fit into that no bother.

Of course, you paid for something that hasn't been supplied so you would be correct in getting it replaced.
