Plumbing Installation Issues. Your advise would be appreciated.

How did you pay? Cheque or card you can cancel or reverse the payment.

Nothing wrong with the control in the corner. If you didn't say where you wanted it then how would they know. This is the only point where I might think the contractor wasn't at fault. I'm not having a pop at you OP

Never a better time to utter the phrase "Cowboy's Ted!". Are you sure it was vans they departed in, or on horse-back? 😧

But as far as it stands, you hold the cards as the reminder of the work isn't paid for, right? And you have it very well documented - there's no defending that utter slap-dash of a job. I think your one mistake so far was not marking out where the controls should have gone - maybe take that one on the chin.

Very poor level of workmanship.

1 major issue which could be a disaster. The blow off vale the one with the red cap 3/4 ways up the cylinder isn't piped out to a drain or outside with a tundish.

If that blows a leak on you rads would be the least of your worries.

The heating coil return looks like its not connected. {Elbow on bottom. Its possible is to be connecting to the lever valve behind the lower expansion vessel}

No hot water its possible there's other valves somewhere which are turned off.

Hold back the rest of the money until job is sorted.

Unvented cylinders have to be installed and serviced yearly by a certified plumber in UK .

I'm surprised theres no such regulation in Ireland.

I very much doubt that whatever warranty OP has on the cylinder is valid if the installation is left like that.

I thought you were going to tell us you had paid them in full. You are in great shape if you hold the money.

Just tell the boss the money is waiting for them when the job is put right.

Can you video the external boiler as at the end there that overflow pipe is incorrect as it should be 32mm when external to the boiler.

Has a bypass been fitted etc? Two pz2 screws take off that end panel to have a peep inside.

If you touch it yourself you rule out a court ruling in your favour.

You have to allow the contractor the option to rectify the issues first. It isn't unusual to have drips after the job is complete. Obviously these leaks should have been identified at the time of testing. I know there is a lot more here than a few leaks but the principle is the same. If contractor doesn't want to or is unable to rectify the issues then you can engage another company to fix the many mistakes. You can bring original contractors to court and have them pay for new company to fix their mistakes.

Once you go down the road of DIY repair you have no comeback with original contractor. As has been suggested before you should have a report drawn up.

It was obviously a rush job by a crew that had nothing to gain by ensuring it's done properly, probably owed money from the same guy that gave them the job and on the verge of quitting working for him by the looks of it.

You've got to take responsibility for the situation yourself though, you know how things work and you know good tradespeople are hard to find.

You should have tried harder to ensure you were paying for a competent person to do the work, fail to prepare.....

On the plus side if it's any consolation your video was like a DIY Prime Time investagation.

RGI is tightly legislated but do Fcuk all to regulate. They’re an absolute shambles of an organisation these days.

OP, the expansion vessels are not upside down. That is the correct orientation. Red is too close to the floor.

what’s pressurising the hot water cylinder?

you should have told them where to put the timeclock but saying that, they should have asked.

I could nearly bet who the installers are on this job. Big company that send out installers is never the way to go. Nearly always cowboys.

Just so we're clear, how was it suggested by them that they had fitted a Wellmaster Joule cylinder?

I see. Pure sham. I'm hoping that you're making progress on getting this properly resolved.
