admittance

Hello all, We just finished renovating our house and there are some issues with the plumbing: that is, our shower has a terrible smell. During the renovation, we had a last minute change to move the toilet down the hall. Although it is a new renovation, we did clean it to make sure there is...

In the photo there is a grey 32mm push fit elbow between the sink trap and down pipe. I want to replace the elbow with a "male" push fit tee attached to an air admittance valve to stop gurgling noises. I can't find a tee fitting that description, can anybody offer a solution as you can see space...

Water nearly rises to top of pan when flushing toilet then very slowly lowers. Tried several attempts to clear any blockages, hasn’t made any difference. Would a faulty Air Admittance Valve (stuck in shut position) prevent the normal emptying when flushing?

Hi, I am installing a new en-suite toilet upstairs in a new location , the soil stack is installed by my builder going downstairs directly and into the ground where the main sewers are. He’s installed the air admittance valve on the floor below , which is slightly below where the toilet is...

Doing a split level custom build. The plumber wants to install AAV's on some of the lower level lines, a bathroom and a bar sink. There is a way to vent them normally through the roof, it's just more work for him. Which is better? The floor above hasn't been cast and a vent can come up through...

Hello, DIY plumber here, I’m after some advice regarding an AAV, my current one goes though the loft and the roof with a vent on, iv seen on some pan connectors have 32mm air admittance valves built on to them. Does this mean I don’t need the 110mm pipe into the loft at all? TIA Tom

Hi everyone,, I'm a keen DIYer and need some advice on AAV or durgo valve,, we're renovating our house and plan to put a bathroom on the other side of the house, we currently have an old stack going straight up through the roof which is open to vent naturally, we plan on putting another soil...

Hi I want to fit an external air admittance valve to a new stack pipe, see picture. Does anyone have a particular recommendation. Many thanks Paul

Please see pic! I can't seem to fit this air admittance valve on the back of the toilet. Is there any other fitting I need for this to work.

Hi Everyone, We have a new house that may not have been piped correctly. There is a sewer smell in the laundry room and I am thinking of adding an air admittance valve to the standpipe in the laundry room since I do not know if the drain is connected to a vent pipe. Would that be okay to do to...

I'm renovating our upstairs bathroom. At the moment the soil stack is boxed in a corner within the room and exits straight through the roof. I was reading up on air admittance valves and I believe the regs say it has to be more than 200mm above the highest point of entry to the soil pipe. So I...

Morning all. Quick bit of advice, yesterady and this morning there was a musty smell in my downstairs loo. Ive had this problem before where it turned out the air admittance valve had failed. This was replaced and cured the problem, however, ever since the new one was fitted, the valve makes a...

Hi I'm adding a shower in my loft and the waste is going to be long one, routing downstairs into the 40mm waste after the bath, and the advice seems that I'll need an AAV at the top of the run. It'll look a bit like the attached ASCII art. Yes I realise the vertical drops aren't ideal but...

Hi I have a client who has three WC's served by one long waste pipe feeding into a soil pipe. When the WC on the far left is flushed it causes either one or both of the other WC 's to overflow. I think it must be because an Air Admittance Valve has not been fitted? Would you agree? If so what...

Air admittance (Durgo) valve: A1 designated. Any recommendations please (ease of fitting, longevity, functionality etc) for an ‘A1’ designated Air admittance (Durgo) valve needed for a forthcoming conservatory roof replacement/upgrade?... i.e. a valve that will be fitted below the flood...

Hello Everyone Thanks for previous advice on an Air Admittance Valve height. I have fitted the AAV, see picture, but each time I flush the WC the WC pan fills up to over 80% capacity before it slowly empties. I dont think the AAV is working well enough??, because if I lift the valve slightly...

Hi Everyone I am fitting an air admittance valve to a stack pipe in a bathroom, see pictures. A separate washbasin waste pipe and bath waste pipe are also connecting to the soil pipe. I have fitted an anti syphon trap to the washbasin and a HepVo to the bath My question is Is there a...

Hi, Back again after the excellent advice last time! So when the BCO popped round last week, he mentioned about an AAV in the toilet. I said it shouldn't be needed, as I have a vent stack, but it has got me thinking. So a bit of advice please! The toilet set up is exactly the same as...

Hi Looking for some advice please. I’m a home owner of a new build home less that 1 year old. We have had an ongoing issue with what I believe is sewage gas building up in the loft space since we moved in but I could never quite pin point where it was coming from and it would be intermittent...

Hi all Our externally vented ‘traditional’ stack vent (through the roof) kept leaking through the roof with rain water so to solve the issue for good we cut off the stack pipe in the loft and fitted an air admittance valve and got a roofer to patch the roof in late April. All was fine until...
