I have noticed the pressure of our WB 30 cdi boiler increasing over the course of a day or so. I have bled rads upstairs although downstairs is wet UFH.initially I did get some air out and the pressure dropped,then proceeded to fit auto vents to the towel rads throughout the house.The pressure...

Makes sense and I am guessing I have no recourse even though I have a certificate? Probably not worth the paper it is written on! Only been in the house since October and had problem after problem so getting pretty down about it all now, especially as the building itself is really well...

Gets worse! Just had a good look at the garage CU. SWA not earthed there either! Should there not be a tag that is connected to the earth rail in the CU? The other really odd thing is that I have a main earth that goes no where. It is just chopped off near floor level and there is no sign of...

SWA is landed and earthed at the garage it appears. Is there a requirement for both ends? I just cannot see how this was signed off but one bit of investigation at a time. I will open the CU at the garage tomorrow to check that out. Is the switched fuse still the preferred option in the cupboard?

The cable run is around 15 meters to the garage. I have attached a picture of what I have at the meter cupboard. Not sure what size SWA it is though as can't see any markings. I will get a pic of the CU in the garage tomorrow. The cable runs from the white cupboard on the house to the side...

It appears the SWA cable feeding the detached garage is simply terminated inside the meter cupboard, strait in to a henly block. The cable which i think is 6mm2 feeds a consumer unit inside the garage. By my thinking, some type of device should be fitted in the cupboard as nothing is protecting...

Thanks for the replies. The valve is opening so i will disconnect the signal wiring and check the switch to try and work out what is going on

Hi all I am having a very strange issue with my hot water. Basically, and it appears intermittently, the boiler will not fire when there is a hot water demand from the timer and stat has not opened. The boiler is a worcester Bosch Greenstar 30CDI system boiler. My home heating and water are...

Have a search for Dryline pro, they are designed for this type of job and work really well. I used them a lot in my previous house with thermalise block and dot and dab walls.

No mention of possible damage was mentioned prior to starting work. I would have no issue in repairing the area (around 18" square) that is stained as long as the paint matched and was not visible when dry. If there is one thing I hate, it is a patchy painted ceiling. We only moved in last...

While not a plumbing question really, I wanted some opinions on how to reach a satisfactory outcome with this situation. Plumber installed a new tank which sits above the kitchen ceiling. I had to construct the new deck for it and the positioning he wanted meant that the cold water feed needed...

Plumber finished installing a Joule 250ltr horizontal cylinder in my eves space. Water is hot and it appears to be working. I noticed while I was insulating the pipe work that the return is 10 degrees hotter than the flow (water 2 way valve oil closed at the moment and I left 2 small...

IO would guess you need to open the fill line (braided hose) to top it up. Should be a valve at either end and it should not be left connected as shown. The red controls are temp and press relief valves.

Cheers for the info Roger. I will let you know how it goes! Manifold spacing is near spot on and only the feeds to it will need adjustment

I sussed out the problem with the UFH. 2 zone valves were crossed over so increasing demand for heat in the hall was simply heating the kitchen! Flushing was actually pretty easy and I did get a little bit of debris out which must have been in there since new. I am sure that either the original...

Excellent, thanks. As the pipework is already bent with the pipe supports and in the screed then there should be no stress. Do you think it is possible to remove the old fittings without cutting back the pipe?

I currently have a wirsbo manifold located aprox 25cm from floor level in a utility room cupboard. The manifold has been a pain recently with sticking valves etc etc. I am looking to replace it with an Uponor vario B manifold with flow indicators but i note the instructions say to mount it a...

Thanks both!

I have got myself confused with the IP rating required for some on-suite downlights. The ceilings are 2600mm and from what i can work out, this falls outside the IP rating zones? Can anyone please clarify?

I found some instructions as this type of manifold is discontinued, however i am confused where it says to close all underfloor heating loop flow and return valves. I assume i just remove the actuators from the flow manifold to close those but am unsure about the return manifold. Does it mean...
