Plumbing dilemma

[toolsntat]

Is there a reason I shouldn't cut this 28mm pipe to give access for ply shelving sides (the bottom was hard enough!) and then reinstate with a straight compression fitting?
As far as I'm aware it is a drain off pipe from a Tundish and a pressure relief valve.
It should be said that the sides cannot be lifted over due to ceiling height.

Can't see why not. It's a gravity drain from a tundish - so is empty. As long as you re-instate it should be fine

Ok cheers for that.

Can I suggest that while you are at it, it might be worth considering re routing it behind the vessel on the right? Clip it to the wall and make sure that it falls in the correct direction. It would also make it easier to access the vessel on the right and be less prone to mechanical damage.

Hi

This looks like a sealed hotwater system and as such comes under the legal requirements of the G3 regs. One of the regulations states that any water discharged from a heated vessel must be discharged safely and visibly, the tundish allows you to see if there is any discharge. To sumarise any modifications or alterations should only be carried out by a heating engineer that is G3 registered and I believe they are now also notifiable to the local building control.

Yes, funny you should say that, they put the clips round for it and then decided not to use em.....
For two pins I'd do it but it's well above my pay grade

Interesting, so the pressure relief valve shouldn't go into that pipe as it's not a visible outlet, or would venting externally be ok?
So the key question is...
Is there a reg to stop me using a tube cutter on that run, moving it then putting it back with the aid of a fitting and 2 spanners?
Suppose they would have to do the same to remove the vessel, so I'll be saving them a job

Hi

I read the post from a different angle, thought you were altering the pipe run which is all determined by regs and for a very good reason, if a sealed H/W cylinder fails to vent on over temperature/pressure they have the potential to explode, hence the requirement for annual safety checks.

Update.
Doing it without removing the pipe would have been a right mare!
All components, including bottom board are now removable using furniture bolts with "t-nuts" and split batten shelf supports.
