I think my hot water cylinder hasn’t been plumbed in properly

[Harvest Fields]

Is there a tundish - and if so, where? It must be clearly visible and within 600mm of the T&P relief valve.
That job is DIY looking and in fact probably could have been done (albeit illegally) better by a competent diyer who actually reads and tries to adhere to the basic MIs.
I am fearing the worst about the discharge pipe diameter size, materials and how it terminates.
That install needs a qualified decent plumber to remove it all and start again with most of the plumbing. No point in talking about the owner messing about with one minor problem. If this has been recently installed by someone claiming to be a plumber, then sue them

Tell us what you really think mate

He isn't answering no more ... he did not reply to quite a few questions from the other lads so perhaps he did

You shouldn't be playing with this it comes under G3 of building regs and should only be worked on by a registered engineer whether installing or maintaining, it looks like a new install so you should also have got a certificate for building regs notification for the work, you need the get the installer back assuming he/she is G3 certified if not employ someone who is, don't want to over dramatise but if not installed you could create an explosive situation

Going by the pictures an just the fittings used alone looks like a DIY job in my opinion,looks like one of my boys meccano sets
