USA Unvented cylinder - water pressure

[Tim0212]

Hi, looking for advice about unvented cylinder. I had one installed as part of a horrific modular loft conversion that was recently finished. The water pressure in the bathrooms is poor, probably worse than when just had combi and I cant use two showers/bathrooms at one time which was the point in having it installed. When first installed it seemed good but then there was a leak in the system. Leak was fixed but pressure now poor. The tested cold incoming measures at 22 lpm and 3 bar but when i check this in bathrooms its less than 8lpm. The plumber is refusing to return as loft company arent paying him(think theyre going under) and his only advice is that the incoming supply is the issue. Im not convinced though due to rate during test and i've recently tested outside tap and its 3 times quicker than inside. The new shower in loft occassionally has fluntuating pressure that you can see by eye. Does anyone have any advice?

Hi Riley. Not sure whether you have facebook but if do check out this post ive done documenting loft debacle Tim Elson

 

[Riley]

I don’t but I got nosey on lunch and did look them up and a few of their attempts to block negative feedback

 

[Tim0212]

They very recently took doen all social media pages. Must be on way out...

 

[Riley]

Shame that they seem to think this treatment of customers is acceptable

Wow!!

 

[Riley]

Can someone post a couple of the pics on here. I’m intrigued

Click the link you don't need to be signed in I think

Dunno I haven’t got FB

So i have his license number. He has a tick against vented hot water storage but there isnt category for unvented. Does that mean he hasnt got G3 ticket? Is he likely to be worried enough that hes been found out to fix it? I have another local firm quoting on Thursday.

 

[ShaunCorbs]

He still might but looking not likely

 

[Riley]

I’d put it to the Plumber and ask if he’s G3 qualified

 

[Riley]

To be honest I don’t know why I’m bothering based on that install he shouldn’t be

 

[Tim0212]

Update. Local firm came round and i await quote to resolve this. They advised that along with the direction of the cylinder the installer has also put the expansion vessel on the hot side. Plumber will not answer phone and loft company arent doing anything. He advised he wouldnt have put it in this location and pressure will be effected by incoming pipe and isnt sure whether are two rainwater showers will work simultaneously. He has asked us to check the shower requirements and i cant really understand from the website Lusso Luxe Three Way Thermostatic shower set with Handheld shower & Spout matte black | Showers ???

Our outside tap measured at 3 bar and 22lpm

I’d be suggesting you will almost certainly need to enhance your incoming to achieve any of the top end results. Let alone running both showers at the same time. Most cylinders of that size can produce around the 50lpm mark, some more some less, but this is intrinsically linked to the pressure and flow rate leading to the cylinder.

 

[ShaunCorbs]

Showers want around 44lpm for both

I don't understand why you haven't contacted your local authorities or who ever is in charge of licensing. It sounds like you paid thousands of pounds for garbage that you were told was correct and it all needs to be taken apart and replaced. I would be livid.

I think the longer you wait to hold these guys accountable the worse it will be for you.

 

[Riley]

I see you’re in the USA sadly it doesn’t work like that here. The regulatory bodies are pretty toothless

 

[Tim0212]

• Indeed, it seems as though i'm powerless. Awaiting quote which is likely to be over the 2k that im holding back. Loft company going under and unable to contact plumber so will follow process in terms of getting quote and formalising to loft company. I will go on a big list of creditors. They owe my builder 46k and probably numerous others so dont expect anything if over 2k. Ive reported to trading standards and will to gas safe but dont expect any help. Dire indeed.

 

[Riley]

Happens all too often unfortunately

Can't pump mains water

yes you can, Salamander and a couple of others are WRAC approved

 

[ShaunCorbs]

yes you can, Salamander and a couple of others are WRAC approved

12lpm which is no use to anyone on an unvented

Wow, thats some installation !
Rectifying that set up is whats going to be hard

It is a legal requirement for anyone installing unvented cylinders to be trained and qualified. It must also be notified to building control.
There are unvented cylinders made to be horizontal.
