Hi Quick question. I have a system boiler (Worcester Bosch). There is a Magnaclean filter fitted, which I assumed was just on the central heating. Heating was turned on a couple of days ago and the pressure on the boiler has been dropping. Last night I made sure the heating side was turned...

Hi I have been trying to remove my cistern filler as it is constantly running so I have decided to replace it. I have removed the flexible hose supply pipe from the base of the cistern, but have noted that the large white plastic nut clamping the filler in position is recessed into the vitreous...

Thanks.

Hi I am about to brick up an external door in an external cavity wall. Both leaves are brick with a 75mm cavity (1960’s build). Two items that I need some advice on are as follows: 1. The cavities at either side of the opening are closed with brick – do I need to cut the brick out to...

Hi I have a 1 sq m area of concrete floor to damp proof and screed. I was planning to use synthaprufe, blinded with sharp sand and then lay a cement sand screed over. However, the thickness of the screed at a minimum would only be 30mm (it increases to about 50mm across the width). I have...

Hi I have a doorway to brick/block up in an external cavity wall. External skin will be bricks toothed into existing to match. The existing inner skin is common brick (no plastered). I was going to use some left over thermalite type blocks to block up the inner skin, but was wondering if when...

Hi I have fitted a timber wall plate to side of house for lean too roof. Roof is all on and I have just started insulation. I checked Rawlbolts (done with the resin) and the nuts were not that tight (they were when first fitted about 3 months back). I have tightened them a bit with a spanner...

Hi I am building a small lean to extension, brick/block cavity wall and concrete tiled roof. Planning to have a traditional mortar bedded verge using fibre cement undercloak. I have two queries: 1. Should the undercloak be bedded on mortar (appreciating it fits under the roof batten). 2...

Hi I have fixed all my rafters on a small lean too. I had checked the line/level of the top of them before fixing and they seemed pretty much fine. Now fixed there seem to be a few that are a few millimetres out - when I put along straight edge across there is a gap of perhaps 2-5mm at one...

Hi I am building a small single storey lean two extension. My query relates to the eaves wall plate. I understand this is to be bedded on mortar on the inner skin of blockwork. Should the plate be cut to fit up to the inside of the return/gable blockwork, or should it pass through the gable...

Hi there I have a Worcester Bosch Greenstar system boiler. On turning on the central heating this week I noted the pressure was a little below 1 bar so I topped it up to the 1 bar mark. Fired up the heating again and noted later that the pressure gauge was well into the red - around 3 bar, but...

Hi, I will be having my 1960's semi-detached house re-roofed very soon. The old battens were rotten and the felt was falling apart. The old battens were 19mm-3/4" thick. The roofer has advised that to avoid an issue at the join with next doors roof they are going to use 19mm x 38mm battens so...
