Leaking Valves

[gassafe]

the condense pipe should connect after the trap.

the speedfit fitting looks like hes bodged the magnaclean on after cutting the pipework to short.

I'm guessing the trap is built into the boiler like most others!?

Just had another gas engineer in to inspect the work. Seems like he's fitted the magna clean to the wrong pipe and the flue is at a slight angle which could cause rain water to ingress!

I'm sure manufacturers stipulate not putting additional traps in the pipe work after the one in the boiler so if connected to internal waste pipe work serving other basin's sinks or appliances it should do so after any other trap on the waste pipe work not sure why. I think it is intended for running traps that might prevent the syphon action of the trap in the boiler from working properly.

As long as the angle is slight then that is as it should be.

What about the magnetic filter? Does it matter if its fitted to the flow or return?

well yes and no just means any dirt/cr*p will pass through the boiler first and then into the cleaner

I don't understand the logic behind that. The Adey website states the filter can be on the either the flow or return, return being preferable. I thought the primary idea of the filter was to prevent grime getting into the boiler from the radiators. If you fit it to the flow that logic no longer works so how exactly is it protecting the boiler if there is some dirt in the radiator it will still end up inside the boiler?

What if its a fair bit of an angle where rain water can get in?

yes i can be fitted both ways but is recommended to be fitted on the return pipe to the boiler to say rubbish going through the boiler

The volume of rain water that would enter the flue if it is fitted with the correct slope back to the boiler is small and will not damage the boiler if it travels down the exhaust portion of the flue then it will enter the condensate drainage system and be carried away.

Please don't miss understand I don't think the pictures you have posted are of a good and care full install varied out with pride but the points raised to date don't necessarily mean it is incorrectly installed.

Not ideal as it really needs to filter the debris out of water returning to the boiler but either way it will reduce the amount if floating deposits that might clog or damage the boiler and pipe work assuming of course the deposits are ferrous.

I've attached some pics - what do you think, does it look correct?

I've noticed the shower head is also dripping and weeping from one of the nuts. I'm beginning to think this might be due to the increase in pressure converting from an open vented system where the water was stored in a copper tank in the loft to a combi system. Could this also explain the weeping radiator valves?

If its due to an increase in pressure whats would be a recommended fix?

I've had two gas safe engineers neither seemed to know why the rads or the shower is weeping?

Looks a little too steep to me which is making it a touch to short to by the looks of it. If it were sitting at closer to the correct angle it would probably be the right lengt. Perhaps check behind the black rubber shroud that the wall has been sealed to the flute.
Even at that angle which looks to steep the volume of rain water likely to be collected is small. I would be more concerned that the flue and the junction may be under strain as a result of sitting at that angle.
You are obviously unhappy with the install.
How do you intend to proceed?

 

[Adam78]

I've asked gas safe to do an inspection. He didn't seal behind the rubber shroud. The edges of the hole were packed in with bits of broken concrete and the shroud placed over to cover it.

+1 too steep by a long shot normaly 1 to 3 degrees mi say

Would gas safe switch the gas off. I don't really want the gas switching off?

It is possible that both your shower and radiators are weeping as a result of the change in pressure that they now have to withstand.
But be aware that the shower and its plumbing is now subject to mains water pressure. Whatever that maybe in your area (it can vary from day to day and minute to minute) the radiators should be subject to a minimum constant pressure of about 1-1.2 bar increasing when the system water in your radiators is hot but should not approach 3 bar.
I may be stating the obvious but your radiator loop and heating pipe work are entirely independant of the plumbing and water to your shower and taps.

Only if their checks discovered defects associated with the gas pipe work flue or Boiler considered dangerous.
