I have a soil stack in the corner of my bathroom which has an AAV on the top (above basin waste height).

the toilet connector feeds into the stack and below that a 40mm waste goes in. The 40mm waste takes away water from the bath and basin. Quite a long run from the bath and the 32mm basin feeds into the 40mm pipe with a reducer and a tee.

When I have a shower, there seems to be an air lock / vacuum and draining is very slow. If I flush the toilet it just fills and drains very...

When planning the new layout, the durgo valve is the stumbling block. It was in the unit attached to the sink unit, but the layout never worked well. It seems to be that the toilet waste runs along the wall (used to...

Any experience with external oil boilers? Sat, 02 Jan 2021 22:41:21 +0000 /threads/any-experience-with-external-oil-boilers.233544/ /threads/any-experience-with-external-oil-boilers.233544/ (lohr500) lohr500
In doing some research I see that various manufacturers do external versions of their oil boilers. The costs aren't much more than the internal versions of the same units.

The existing floor mounted boiler is built into the kitchen units so it takes up space and can be heard.

There is plenty of space on the other side of the external wall directly behind the existing boiler. It is an unobtrusive...

Boiler pressure fluctuating Sat, 02 Jan 2021 22:39:04 +0000 /threads/boiler-pressure-fluctuating.233560/ /threads/boiler-pressure-fluctuating.233560/ (Will83) Will83
Had Worchester Greenstar 2000 combi boiler installed 5 months ago. Heating works as it should, also there is no issues with hot water either. What i've noticed that pressure gauge sometimes at 0.5, and sometimes at 1bar. Not sure what is causing this fluctuating? No visible leaks, i did have a look at all rads.
Can someone advise please.

Thank you]]>

At the moment I have Hive working with a boiler and HW tank. That all works perfectly with the Hive time controls and normal Drayton TRVs (although they seem to be the work of Satan in terms of control!)

The Hive TRVs appear to have the functionality that I'm looking for BUT the user experience is dreadful - the things appear to be not fit for purpose and there's no sign of any improvement...

Air in central heating after THREE MONTHS! Sat, 02 Jan 2021 20:34:08 +0000 /threads/air-in-central-heating-after-three-months.233230/ /threads/air-in-central-heating-after-three-months.233230/ (BiancoTheGiraffe) BiancoTheGiraffe
I've still got air in my system, three months after the new boiler was installed!

I'm sure it's down to the crappy plastic pipes that have been rammed into walls and under floors with no attempt to keep them straight and level, but I'd really expected it to have settled by now!

Could it be drawing in air from the vent pipe?]]>

Have an issue with a radiator - had a failed motorised zone valve which I replaced yesterday and when checking the radiators were subsequently warming up I noticed one was only like warm at the lockshield and relatively cool along the bottom 1/4.

Don’t think the events are linked, but since finding this issue I’ve tried to fix and can’t make...

I have the following pipe layout in my house as shown below, but I have a couple of questions for you folk that clearly know more about this than me :)

With regards to the highlighted points in yellow on the diagram below...

(1) Am I losing 50% of my flow before the hot water even hits the Central heating or Hot Water Cylinder?
(2) Why is the flow from the pump going to both the return outlet and flow inlet on the Water Cylinder?
(3) Should this balancing tap be replaced with...

The radiators take ages to warm up so whilst I have the floor up I will insulated the pipes
My question is whilst the floor is up shall I swap the 10mm to 15mm or will insulating the pipes do the job

Complete novice here. Need to remove two towel rads to redecorate behind.

not too sure how to close down the valves - the left hand side doesn’t seem to have a spindle that I can turn (based on a YouTube video I watched)

Steps to remove would be helpful if someone could assist.
