    Kitchen Extractor Hood - Preventing Backdraught

    We get a terrible draught through our kitchen extractor which vents outdoors. We have tried various back-draught flaps in the duct and hoods on the outside, but to no real avail. In all cases, the wind blowing past the outlet on the wall seems to pull the flaps open and let in a draught at the...

    Hardie Backer Board or Ply to Overboard Wooden Floorboards in Bathroom

    There are many threads on this topic already, I know, but I am trying to get it clear in my mind before I waste time and money. We have 22mm (3/4"?) wooden floorboards in the bathroom which we plan to tile with 600mm by 600mm tiles. The boards are sound, but have the usual irregularities...

    Negative Head Shower Pump and Faulty Pressure Vessel

    I am a little puzzled. My understanding of a negative head shower pump is that the pressure vessel detects a change in pressure when the shower tap is turned on. This pressure drop then switches on the pump. The pressure vessel on our Stuart Turner pump is faulty and will not hold pressure at...

    Foam Underlay beneath Hardie Backer Board

    We are tiling our bathroom floor which has 70 year old floorboards exhibiting the usual wear, tear and irregularities. There is also a slight bow to the floor, albeit only noticeable with a long, straight edge. Replacing them with chipboard is not really viable because two of the original walls...

    Converting Positive Head Pump to Negative

    I plan to fit a shower pump as we have low water pressure. The flow is about 0.5 litres a minute through the shower head, so is unlikely to be enough to start a positive head pump. I have read in another thread on here that you can buy add ons for pos.head shower pumps to be able to convert...

    Screw Length for Tile Backer Board

    I am using 12mm insulated tile backer board, similar to Wedi, in our bathroom. To give space to run pipes behind the board, I am screwing 18mm by 44mm battening to the wall at 300mm spacing. The board will be glued with Mega polyurethane glue and screwed as well with washers. Will 18mm screws be...

    Cutting Holes in Joists for Pipes - Strengthening

    We are planning to fit a shower tray in our upstairs bathroom, but to reach the waste, I would need to drill through the joists. I am concerned that this would weaken the joists and lead to problems in the future. I have seen that in America, you can buy steel reinforcing plates that have a hole...

    Wooden Floor Preparation for Tiling

    We are planning to tile our bathroom floor: I have seen so much conflicting information that I am confused and should like to try and get some clarity before starting. We have sound wooden floorboards. My plan is to do the following on top of the boards: - 6mm Hardie board (from Topps...

    Shower Trays with Tiling Lip

    We are planning to fit a shower tray in place of the current bath. I believe that you can buy trays that have a lip that goes behind the tiles to create a water tight joint. However, all of those that I can find have a flat top, on top of which the tiles sit. Does anyone know of a make of tray...

    Insulating a Tiled, Solid Bathroom Wall

    We have a 1950s property with solid brick walls without a cavity. The bathroom is cold and suffers from condensation. It has two outside walls. We plan to replace the bath with a built-in shower which will need to go on one of the outside walls. Relocating it is not an option due to the shape...

    Installing a Stone Resin Shower Tray on Wooden Floor Boards

    We are planning to fit a stone resin shower tray into an upstairs bathroom that has wooden floor boards. It needs to be as low as possible and not up on adjustable legs. I plan to ensure that the existing boards are in sound condition and then lay a thick sheet of WBP plyboard (18mm or so) on...

    Suitable Finish for Mahogany Parquet Flooring

    We are restoring the 1950s mahogany parquet flooring in our living room and hallway. It is sanding up well and has a good, even surface, clear of all old finishes. We are considering using either Fiddes Hard Wax Oil or Ronseal Diamond Hard Wood Varnish on it, but wonder which is likely to be...

    Which Way Around to fit Radiator Valves

    I am plumbing in some additional radiators and would like to clarify which way around the valves should go. Does the check valve go on the side where the water goes into the radiator or the side where it flows out? I have been trying to clarify, but have read some guides which say to fit it to...

    Fitting Insulated Plasterboard to a Solid Wall

    I have been looking into how to do this and have been finding mixed information. Can anyone give a clear answer, please? We have solid outside walls which are rendered. The rendering is in good condition as it was re-done last year and there is no damp. The internal plaster is sound. We wish...
