No drain off tap on hot water cylinder...new cylinder required?

[snowhead]

why does a cwsc need to be on 25mm marine plywood to pass regs (or so i've heard) but an unvented cylinder can be put on chipboard?

Plastic verses Copper / Stainless

This is one of the stupidest things I've heard a so called plumber doing. All he needed was a spanner and a hosepipe!

 

[rocketmanbkk]

The plumber is very stupid or didn't give a monkeys

Who in their right mind would undo an immersion & take it out a full tank??

It must've been like a tidal wave.

Craziness

I can't believe any plumber, G3 or not would do a live Immersion swap with a low level immersion. What a tool.

I would love to have seen that...

I would love to have seen that...

I want to know if he even attempted to catch some of the water

 

[Jay The Plumber]

I want to know if he even attempted to catch some of the water

yea, with the electrical enclosures perhaps

 

[SmokeyJ]

If the plumbing company has any sense mikey the plumber will be unemployed not coming back to remove your cylinder. Guys crazy

 

[Radioman]

I wouldn't pay anything at all, in fact down here he or they would be lucky not to end up in court. At least with a massive claim on your public liability.

I wouldnt worry too much about the cylinder falling through the ceiling, it wont fit between the joists!

 

[Stigster]

Is that another appliance teed into the D1 expansion relief pipe?

 

[Riley]

Would imagine it's just the PRV from the block

 

[Riley]

Sorry see what you mean now. Yes it does. I'm guessing PRV for boiler if its above

 

[GasmanxxxR1]

probs prv from heating

Thanks for the reply. I am in fact trying to interpret this as found in the MI for an unvented hot water cylinder.

3.53 Where valves other than the temperature and pressure relief valve from a single unvented hot water system discharge by way of the same manifold that is used by the safety devices, the manifold should be factory fitted as part of the hot water storage system unit or package.

What is the "factory fitted" manifold of which they speak?

Sorry if I'm missing something obvious. I have my UHW10 as required by the Approved Document G3 but I have not had to combine more than one appliance into the discharge system and wish to understand this requirement.

No idea?

I used to do immersions live quite often and they were 9KW ones on 2000ltr cylinders.
They were in tanked external plant rooms though!
would gently undo then quickly rip out and offer up 4'' waste to direct water out the door.
Cut a days work to 2-3 hours (need a change of clothes too).

Things are very different now!
