Hi, first time plumber and poster here.
I've installed two new zone valves and replicated the direction inwhich the original valves were installed. I'm really confused now as I think the originals may have been installed the wrong way round.
The Grundfos pumps' arrow is pointing down whereas my...
When there is no demand for heat and the system is "cold", the flow temperature displayed on the front of my WB boiler is still reading 41. The flow pipe feels cold to the touch, definitely not 41deg... Have I misinterpreted what this display is actually telling me?
Hi All,
We're been living in a new build property for the past 2 years without any obvious heating issues. We've an underfloor heating system that's split across 4 rooms, and is driven by a Daikin ASHP.
I've occasionally had to take the actuators off in order to release stuck pins after...
Hi lads and lasses, I have this customer that has to keep forcing mains pressure back through his vented hot water system every week due to a blockage or air as he explained it. He said it has been like it since he has moved in but has got progressively work he has been there for around 6 years...
Hi, I've recently had a new boiler fitted under the ECO scheme.
The engineer that carried out the installation was in a constant rush.
After the installation he checked all the radiators were hot but I pointed out a loud banging/gurgling noise. He said it was air in the system which would settle...
I had a new boiler fitted December 17
The commissioning checklist is not signed;central heating mode section not filled in;domestic hot water section has incorrect temperature written in(wasn't 50 degrees) so he couldn't have measured it. I am concerned the boiler may not have a valid...

I just came back from a quoting job a time a customer and took this picture. He wants to replace the boiler and therefore we had a meeting regarding bathrooms dn boiler.
To me it looks very odd and therefore...

Baxi 105HE fitted with a section of a Vaillant vertical flue - someone put it as ID and capped, even though it passed all safety checks, including fga. I always thought this would be AR. Am I incorrect in thinking so?
I'm sure we've all came accross the issue falls on flue systems not meeting m.i's, it's become a matter of great debate in a few apartment blocks i've been working in recently, especially when it comes to clasifying ncs or ar, personally my view is ar along with a few others then some say ncs...

I have been in my flat for 18 months, it has a boiler with a Vaillant VRT 360f wireless thermostat. Despite its complexity and the terrible instructions I have more or less got the hang of it.
About a month ago the batteries in the thermostat needed replacing. Everything was fine for the...
