Illegal installation

[Gromit]

So here I am again. Illegal installation of boiler and indirect cylinder. Boiler signed off by Gas Safe mate of illegal installer, and yes the system was fired up prior to the signing off.

I've had two engineers look at the system, but both don't agree on their findings.

On the cylinder (photo attached), I noticed that a Honeywell two port valve ( I think it's called) was not fitted. Engineer one says it is is a high temperature cut out and should be fitted and engineer two says it's not necessary and that I have two motorized valves at the boiler which will suffice.

It's hard for me the householder. I feel like a pillock, I've been naive and I'm totally out of my depth. I've employed people in good faith and now I've learnt my lesson to believe nothing unless I see ID in advance. So I've attached two photos of the cylinder, one showing the unused valve.

The other question is with the discharge pipe that comes off the cylinder. It points out of the wall on the first floor and is then bent back to point towards the wall. Engineer one says it's ok, engineer two says it should ideally be run down to the ground, but that it's a grey area.

This is frightening for me - all I want is to get the system safe and then find out how I can stop these guys doing anything like this again.

 

[Toddyplumb]

Simple really , you report the guy who signed it off to Gas Safe. They will come and inspect.

 

[Gromit]

Will do. Is the cylinder a Gas Safe issue? What do you think about this two port valve?

he is right imo. you dont need to double up the two port valves but it must be linked to the safety cut out so depends how its been wired. if its a three port y plan then yes it needs secondry two port

Will do. Is the cylinder a Gas Safe issue? What do you think about this two port valve?

do you have an s or y plan system, has it been linked into the safety cut out?

 

[Gromit]

Thanks Fuzzy. This is the problem - out of my depth. I don't know what an S or Y plan system is. Tough as I'm not in this field and have two experts who disagree, so it's hard for me a layman to judge. This used to be a gravity system - the installer kept the old motorized valves and installed Gloworm system boiler and unvented indirect cylinder.

 

[Toddyplumb]

If it has been signed off by the gas safe guy he has signed to say it complies with the regs.
As to the 2 port valve its as Fuzzy says . Do you have 2 motorized valves at your boiler or 1 with 3 pipes connected.
I would still phone gas safe !

 

[Gromit]

I have 2 motorized valves Toddy. They were originally there from the old boiler from when I had a gravity system. I'm suspicious as Mr Gas Safe is a mate of the illegal who installed it. Since then two qualified guys disagree - one says I still need the 2 port valve by the cylinder as a back up safety device and the other says rubbish.

Also not sure if Gas Safe covers the cylinder - and I bet installer didn't have the ticket for the cylinder either.

 

[charliejamesuk]

Unvented Cylinder installs need to adhere to G3 Building Regs and must be installed by someone with the relevant ticket. Think you can get your local building control officer to check the cylinder install.
Someone else on here will be able to confirm

 

[Gromit]

I thought as much. The thing is I can go and complain. Unless Gas Safe / local authority / Trading Standards have teeth and do something I'll just be left with a flawed installation and no action against the rogue trader. For now I'm trying to gauge whether I have a problem and I've got two qualified tradesmen disagreeing so not sure whether I do need the 2 port valve by the cylinder in adddion to the valves by the boiler.

 

[marsaday]

i am not a plumber, but it sounds like you dont really have a problem. one guy says all ok, the other says not needed. it has been signed off, so you have some come back. not sure what your problem is.

as for the overflow. You direct the over flow in towards the building so hot water doesnt spurt out on to someones head. Or you can run a length down to the ground to discharge at foot level. both are ok, and not really worth worrying about. Our boiler overflow points inwards to the wall. no probs here.

 

[Gromit]

Thanks but one guy says all ok and one guy says illegal and dangerous. Both qualified and ones right and ones wrong.

 

[PlumbBobBob]

i would be inclined to get a third opinion and go with the majority.

 

[metaldust9]

i would proberly read up on how it should be fitted check it against yours then go from there

 

[Toddyplumb]

As marsaday says he is not a plumber. If it is the tpr valve it is highly unlikely that turning it against the wall will be acceptable, it is an unvented cylinder.
The 2 port valve will only be OK if its wired to the thermal cut out.
The bottom line is you are not happy with what a Gas Safe installer has done , you complain to gas safe !

 

[northstar]

What area do you live in ? see if one of the local guys on here can come and have a look for you.

 

[quality]

What about getting the guy who signed it off back so he can put it right

 

[Gromit]

Cheers Toddy. The two port valve wasn't fitted to the cylinder. Installer said as there are existing motorised valves next to the boiler which were already fitted to the old boiler when I had a gravity system that he shouldn't fit the two port to the cylinder. I could get gas safe guy back but he is not qualified for cylinders. So I therefore got two guys with the ticket for cylinders and guess what they fundamentally disagree. And here lies my problem.

 

[Toddyplumb]

The plot thickens. Building control then for their advice

 

[plumberdarren]

To install an unvented cylinder you need an unvented certificate , if that installer has got the certificate and cannot self certify then building control need to come and inspect the installation (different councils are different but about £200). If your unsure you should do that its not a gas safe issue.

 

[Gromit]

I did. And they said "talk to person with qualification to G3 level". And I have. Two of them. Anyone got a gun and a single bullet? Toddy are you saying that existing motorized valves are ok so long as the wiring to the cylinder is tied into these? And even if it is, what's to stop me having the two port valve supplied with the cylinder also wired in - kind of belt and braces. Or is it technically not possible to have two lots of valves wired in?

 

[quality]

Why is the 2 port valve lying on the floor not connected to any pipe work ?

Its not a grey area,
Low level the discharge pipe should run to a drain gully and be lagged if on the outside of the house but can also terminate 100mm from ground if safely away from children


High level discharge can;

Discharges at high level; e.g. in to metal hopper and metal down pipe with the end of the discharge
pipe clearly visible (tundish visible or not) or onto a roof capable of withstanding high temperature
discharges of water and 3m from any plastic guttering systems that would collect such discharges​

(tundish visible).

This is frightening for me - all I want is to get the system safe and then find out how I can stop these guys doing anything like this again.

Hope this helps Eco

Hi Quality. The installer said that the two port valve has not been connected because there are 2 x motorised valves next to the boiler which negate the use of the two port valve next to the cylinder. From what I understand from Toddy on this site, it may well be the case that the existing motorised valves next to the boiler do indeed negate the need to connect the two port valve next to the cylinder so long as they are wired in.

To further compound my confusion I have had two seperate engineers with the ticket for unnvented cylinders one of which says I have to have the valve and the other says no I don't as I already have an S plan system with 2 x motorised valves. This is my problem. Who to believe.

If you have an s plan system, with a zone valve for the hot water, you do not need the zone valve which has been delivered with the cylinder, just keep it for a spare for when one of your other ones fail.
