Thanks. That is surprising because I thought the water leaves the cylinder from the the part marked 'boiler flow' and returns at the part named 'boiler returns' which is lower down. The other two valves are for downstairs and upstairs heating. Both of their arrows point downwards. I guess the...

Thanks. Here are the pics. The arrow is visible in the first

Hi all, I have a plumbing system with an unexplained bang that occurs when the heating is switched off. I heard that this can occur if the valve is placed backwards. Can anyone explain to me if the example in the picture is backwards? The arrow on the brass ware appears to point towards the...

All rooms or just WC? Crazy legislation

Thanks. I will look into the pump. Below is an example of a 'cultural' difference I note. Most sinks I saw there use chrome piping, even ones that are not visible. I have no idea if chrome is better than plastic but it caught my attention.

In my own house I don't think the pump pushes the heating system around. It seems to be mainly for the shower. It is a house over three levels. So I am at a loss what to do. I am doing some renovations in the next few months and will look out for places with very convoluted inefficient piping...

I have encountered bad design there too but in this area of heating pipes it seems quite better. How does one reduce velocity? Wider copper pipes? less bends?

I have spent a certain about of my life living in the UK and a certain amount living in Germany. Recently I have been reflecting on the tranquillity of the plumbing systems I lived within Germany. I have done some research on wastewater system design and I am gradually beginning to understand...

Hi, did you ever go ahead and use the TorFloor? I am interested in this system but I am concerned about low thermal mass and creaking floors.

Has anyone tried the Acoustic Wavin AS pipe? https://www.wavin.com/en-ie/catalogue/soil-waste/low-noise-drainage/soil-acoustic-wavin-as

Yes that is the spot. It has been this way as long as i can recall. I will go with bleach. I just wondered is this a common problem but I guess there is no solution that I can do by myself but looks as if it depends on the local authority.

Sorry. That picture isn't very useful. That whole street has this issue and the pic I showed is a nearby property across the screen that is orientated south. I am attaching a picture of the actual property and its algae footpath. https://imgur.com/gallery/ux3fp5e Yup I am in Ireland.

Hi, I have an old terrace shop front. The street is really old and there is no drain for the guttering. It is not an end of terrace. The front of the shop front faces north so there is a fair amount of green staining from the gutter. It is not dangerous but it is a nuisance. I understand there...

Cheers lads. I will aim then to open up, wrap with acoustic pipe insulation, use the oppertunity to install unrelated cabling behind and then packe in dense rockwoolslab in the remaining space.

What about those old style cast iron pipes. Seem to be very much confined to old buildings in the UK but I heard of Americans using them in new builds for quietness

Hi all, I have a three-level, end of terrace house. It has an internal soil stack (black PVC), and it can be noisy. When people on higher levels flush, it is very audible in the sitting room. The stack doesn't pass through the sitting room. It passes through a small groundfloor WC surrounded by...
