Copper cylinder fitting question

DublinDilbert

Hi All,

Quick question, I've to move a copper cylinder as will be getting some renovations done.

In the new location it looks like everything will line up, except the hot water outlet from the top (see attached). Ideally I need to rotate it about 125 degrees ccw. Would I be best to unthread the right angle fitting and re seal it at the correct angle ? I assume flax and some sort of sealant is used on these.

Am I likely to damage the cylinder rotating this fitting? Cause I could work around the issue and leave it where it is.

Thanks

99% of the time removing top elbow and re sealing before re-asembley for new direction, should be ok.

It's the connections on the coil that cause more problems( side of cyl )

Yep as above, can be quite tight tho

Mr ratbag

should move handy enough use a bit of heat so that you don't stress it
flax & boss white or ptfe to reseal

Thanks guys. I was just looking at the new location and I think it will work the way it is. I'll just bring the outlet/expansion up the RHS of the cylinder.

Thanks again

Flax & boss white only in my experence.

Not enough scope with ptfe for angle fittings.( white plumbers tape)

Actually one other quick one, in a pressurised system I always thought the expansion vessel should be on the feed from the boiler and the filling loop on the return.

Just this evening when I was looking at it I noticed that the filling loop and the expansion vessel are both on the hot feed from the boiler.

I'm guessing as you normally only top it up when the system is cold/off it's not major. But thinking I should sort that out too when moving it.

Ideally on the return as it's slightly cooler but as scudo said, not the end of the world

have you tried loctite 55 , i've been using it for about a year now after seeing it at phex last year, much quicker than tape and better than flax, used it on all types of joints inc old gb , never let me down, i think they'll send you a free trial roll if you look on there website

Loctite glue
Hate trying to take it apart afterwards.
You need 50" stilsons !!!

Hate having to replace auto air vents on GRANT Boilers ( factory fitted ) on the 318 return.

I don't think I've ever seen flax leak

Avoid using hemp or flax on water systems and make sure that the paste is for potable water.

WHY NO HEMP ?

I understand the potable water paste part.

Why not use flax?

Yep I have it. I prefer flax on threads

But it's super for likes of swivel fittings
