vent

Hi, I've been renovating my house, and removed the front cover of this vent in my living room, I don't even remember what the front looked like. The vent appears to just be a short pipe but has some channel on the inside so air doesn't just flow straight through the pipe. I have taken this...

I have a simple question, to which I have been getting conflicting answers: Can I cut a section out of a flat roof joist to run through some ducting? Happy for it to be flat channel. The rafters are 170mm. I've seen some info but think it's about floor boards: I have seen enforcement...

Hello all, Whilst gutting bathroom chipboard floor in favour of 18mm plywood that is partially over the utility.room below I have discovered the utility fan duct (50cm) ends near on open soil pipe that is 4 or 5m in length horizontally interfloor. It is not connected. There is a steady draft...

Hi all, could use some input on this because I'm a bit of a novice and need to make sure I'm using the right tools for the job! Our house was built in the 1940s and we've lived there for almost 30 years, and little did we know there was a badly filled-in air brick inside my build-in clothes...

First time poster with limited plumbing experience - go easy on me :) We're doing a loft extension, and will have an internal soil stack serving a ground floor, first floor, and loft toilet - the 3 toilets are pretty well aligned. The soil stack will be 'boxed in' on the ground floor and first...

I am building a level threshold for my bifold on my extension, having an air brick Telescopic vent just below dpc, would clash with the insulation on my block and beam floor. My architect has detail a cavity tray above the air brick, even though there’s a bifold directly above it? Is this required?

Hi I've got a recently built extension with a bathroom. The shower trap is letting sewerage smells come up from it. I've been doing a bit of research and I'm thinking that the issue may be that the soil stack is not vented. The waste from the shower, bath and basin connect to this stack on the...

Hi, I’ve got a ground floor flat conversion in a 1900 ish house. There are 3 air vents above floor level about 2 feet up the wall. Those areas seem a bit cooler obviously and maybe causing condensation ? (There was also a higher level one near the ceiling) You can feel a bit of a draft even...

Hi, any advice would be greatly appreciated. I've noticed a soil/waste smell coming from the en-suite for a few months. Most of the time it's quite faint but on occasions it can be quite noticeable. I think I've narrowed it down to an open stack pipe which vents directly into the loft above the...

Hello I'm after some advice on some external air bricks at the base of a bay window and whether I need to remove concrete around the base of the bay. We've just bought the house and it needs quite a bit of improvement. There's a bit of damp coming through on the inside of the bay. There are...

Hello, Shed roof insulation has been discussed on the forum before, but I'm stuck on one bit: Air Flow Please bear with me The shed is going to be a fully finished space for daily office and studio use. 5.5m x 2.5m -- fairly large Sloped roof, felted Interior is a shell - we're saving by...

Hello, Social housing tenant here who had new windows installed over a year ago. Been getting dead bugs on the window sill and noticed there is no insect guards fitted in the trickle vents. Reply from housing is vents conform to building regs, so nothing they are prepared to do, but i can...

I have just had a bathroom installed, and a Ventaxia extractor fan put in. It has a plastic gravity grille on the outside, and a flat cover on the front. I noticed that it is not doing much to clear steam, and checked the outside grille while the fan is on. It doesn't move. I'm guessing it's...

Hi, The annex toilet has a fan that vents outside, the grille was stuck on (not really secured anymore) with silicone.. the vent inside is unlined.. it's rough like the outside render. Obviously the grille should be screwed to the wall but should the vent be lined inside with a plastic pipe...

I recently got ground floor piping extended to have drain (40mm leading to the stack as in the figure), hot and cold in a first floor room. Only the pipes are there, but I'd like to install a sink and a washing machine as from the (quite schematic) diagram. Note that the washing machine will...

Hello, I previously thought I had a problem with leaking ventilation ducting from an extractor fan vent in the loft caused by steam from the shower fan and/or a leak in the roof. This originally started as a nail had pierced the flexible ducting used to connect the 2 pipes in the loft and...

Hello all, In the last week a horizontal crack appeared above my kitchen window, moving outwards from a plastic vent cover in the middle. I removed the vent cover and found the cavity to be full of fibre wadding which was quite wet and rotten, so I pulled the immediately accessible stuff out...

As you'll see from the below pictures, my cooking hob has an extractor fan. What the kitchen installers failed to do (before I owned the house) was to install a pipe and a vent from the extractor fan hood. This obviously leads to undesirable problems when cooking, more noticeably in the winter...

I've had a constant build up of water in our extractor fan ducting in the loft. This has been made worse by a tear in the ducting causing a leak to spread. There doesn't appear to be water dripping inside the loft from the outer edge of the pipe so I think the seal is secure holding the pipe in...

Hi. Looking for some advice please. I have installed a new pump in my boiler, I first added some cleaner, let it run for 3 days, drained the system, installed pump, added inhibitor and refilled / vented. (the filling loop is in the attic) All the radiators heat up fine and i have bled all...
