pressure vessel mounting

[crollorc]

We had a pressurized system installed at our house by our builders plumber 2.5 years ago.

The pressure vessel (24l intervarem) beside the pump has recently started to droop but it is not leaking (yet!). No water from the Schrader valve so I think the droop is due to the tank being poorly supported.

I guess it should be supported with a wall bracket/straps.

Clearly I need someone do this work. However, (to avoid a bodged job) I want ensure the appropriate supports are used.

What would you guys use?

Sooner rather than later with that setup.

Ours at work was installed like that, as were the neighboring premises.

One day, the unit installed in the company next door, failed. The internal membrane that keeps the air pocket separate from the water inside the vessel split, the vessel filled with water became heavier, and snapped clean off the pipe. The premises were unoccupied at the time so when we arrived for work on Monday morning, the water was running out of their lobby doors and down the road.

As a result, we had a metal supporting stool welded up and rested our vessel on that to take the extra weight. Eventually ours failed too, but the stool held it in place. The new one was mounted vertically and supported on a bracket from the wall.

You have to be special to install a vessel like that

Yes, it is not inspiring confidence in the rest of the system!

Most reviews of the screwfix mount mention that more than one band is needed and that the band clamps are rubbish.

Do you guys know what size band it is or where to source better quality bands/clamps?

Oh sorry mate , here let me google a better quality item for you as you seem to be busy.

Yes, that Screwfix kit is absolutely useless (I bought one). Really you want something like this:

I.e. the pipe enters the vessel at the bottom and it is supported there. But that will be difficult with your existing pipework.

Cheers, that looks more robust and I don't mind getting a plumber to move pipes around if necessary to better support the vessel.

However, the 24L pressure vessel we have is quite wide @ 351mm.

Do you know if that L bracket arm and opening is long enough to fit this vessel?

Thanks for your help!

Nothing wrong with the screwfix bracket if installed properly, or you could go with something Linked this, take out the PRV etc and blank

Never had a problem with the Screwfix style ones either.

We've had this discussion about the screwfix brackets before...

At some point in the past, screwfix sold pressure vessels with a significant flange around the middle. Those straps worked OK for those. Then they changed over to ones without the flange: https://www.screwfix.com/p/reflex-expansion-vessel-18ltr/26891 . The strap is much less effective on these.

Don’t buy your expansion vessels from screwfix ?

I wonder which of the 3 of us buy, install, maintain the most vessels?

Oh I'm absolutely at the bottom of the list, but I do have a 100% failure rate trying to use that bracket!
I'm curious, have you suceeded using that strap with the sort of flangeless vessel I linked to?
We can't actually see whether crollorc's vessel has a flange.

FYI ... tiny flange
