USA Unvented cylinder - water pressure

[ShaunCorbs]

Would this be the reason why pressure low. Sorry, no idea about plumbing! Sucking cold water - what does this mean?

Yes and the 15mm service

It’s a typical builder install

Text the plumber now with what we’ve said then you have a record

Would it now be impossible to remove the cylinder?

I seriously cant believe this. Should i highlight anything other than the cylinder direction. He had discussed putting a pump on the cold water(under the stairs)? Is the pressure on outside tap good because all on 15mm pipe? If cylinder pipework was 15mm would it have been better pressure?

Is that a vertical Tempest cylinder that has been turned on its side and mounted horizontally?

If so, WTF???

Time to get a new, G3 qualified, plumber in to survey the installation and quote for fixing any issues.

I hope you haven't paid the loft conversion company yet... :-(

Was just thinking that. Would have to remove eaves plasterboard wall

I owe loft company 2k for ongoing issues...looks like thats gone.

He’s a cowboy. Should’ve done the cold feed right at the start. An accumulator or similar could help solve your problem but it certainly shouldn’t be at your expense. And no. Pressure and flow rate are key don’t drop to 15

At a minimum

You are going to need to get an Independant report done I think
How much money are you withholding?
Will it cover major work?

 

[Riley]

Get in quick if they are going under as you say, you need to be a party of interest

 

[Riley]

what’s the rest of the install like dare I ask

 

[Tim0212]

Landmark lofts are the loft firm and landmark heating managed the cylinder installation. I dont think landmark heating are in trouble but think landmark lofts are. So incoming goes straight through house and under kitchen tiles. This and feed to cylinder(once correct) would all need to be replaced to get a good flow? The loft firms "engineer" that scoped the job and did pressure and flow tests never mentioned anything about incoming.

Are there other photos that would help with this?
