Low water Pressure ... unvented ...

[Old Account]

hi lads,

Just called out today for a low water pressure issue.

Customer had a diyer according to the install without certification for the unvented cylinder which is just 6months old.

However, Thames water checked outside 25lpm and 1.8bar pressure

Inside 10lpm and 1bar pressure static
Operating is below 0.4bar
which indicates that there is an issue with the supply to the cylinder or am I wrong here?

What can be done to solve the issue ?
Partly lead pipe ( outside to inside celler )

The cylinder won’t functioning with such a pressure or flow rates.
I am also wondering if the flue is correcr installed whoch doesnt seem to me as they used the plume or waste pipe to extend it
Any help or guidance would be appreciate it
Thanks guys

Well in that case you wouldn`t get the job, like some subby`s can`t have sign writing on their vans.

I also hate subbys given their business cards to my customers lol sacked straight away!! People like to burn their bridges don’t they ahah

C`mon Ron don`t get lazy with shortened words like others do.

True! I should write in full but honestly now, I only could check at the mains stopcock taking partly the pipes apart and check directly how many lpm I’ve got. Perhaps it is really scaled up. But thanks to you too by the way

Matchless plumb is the in coming main not the lead pipe that then goes to the stopcock with 25mm mdpe from that to cylinder?

I have just looked back through these pictures mate. Are you just an absolute magnet for disaster workman ship? (There is a theme here)

Which is the incoming pipe?
You could call or get them to call the gas supplier if you think its an ID situation and they will take care of the gas

yes, first lead pipe from outside about 2.5m and then it joints onto the mdpe 25mm pipe which has a run of about 8-10m

I would say that the lead needs to go an be upsized

what exactly do you mean a magnet to get always shitty works or is that again an english saying and i dont get that

Hope all goes well.

Thanks, but i am very certain as i have no time for failures

 

[Harvest Fields]

I mean a magnet to nightmare jobs mate. I go months without seeing Work like that. Nothing bad intended.

 

[king of pipes]

Dont take it to heart bud concentrate on getting yourself qualified, you can then as do as you please and not rely on others all the best . kop

Oh that I call lucky. I can post almost everyday proper bad stuff. I come across a lot of bad installations but people do not take it very serious they are more concerned about their low water pressure even though you point the worst out. They do not seem very frightened more relaxed, quite sad to be honest

Have seen it too, will that cause a big problem as it’s not the first time I have seen it.

Stopcocks have a direction arrow for good reason. Not sure how it will effect the flow of water, but not good. Old stopcocks if jumper not pinned wouldn’t let water past them if wrong direction.
