The drain run would be accessible from an inspection chamber, and yes, using the access point inside would 100% be a last resort, but I thought it would be an idea just in case my kinky idea caused any problems, either at the kink itself (maybe unlikely) or, should the the kink cause any degree...

Cheers for that . I hoped it would be OK, but given that the only reason for wanting to kink the pipe is to have more room on the ground floor I wasn't sure if that would be deemed too frivolous. 2 further quick questions if I'm not pushing my luck. I take your point on noise, and yes, I would...

Hi I'm planning the refurbishment of my house, and I'm looking to add an ensuite bathroom to an attic bedroom. The soil pipe would need to pass to the right of a couple of floor joists, but in an ideal world I'd like to then kink it to create a bit more space on the floor below. There's nothing...

If space is really tight, then there will be a compromise or two somewhere, so I think it depends on what the main objective of the improvement is as to where you'll accept the compromises. Are you looking for a good shower as you only have an over the bath one at the moment? Is the toilet just...

Many thanks

I'm not a qualified plumber, but I've had to do this before. I did something similar to what FiremanT is suggesting. I got an isolation valve (open) with a small piece of pipe then a flexible hose on it to make it easier to direct the water. I had this feeding into a bucket so there wasn't much...

Hiya I have had a look but can't seem to find an answer for what I need to know. I'm about to create an ensuite, but it's quite a long run to the SVP at the back of the property, so I want to add an AAV (pretty sure BC will want one anyway but just at the planning stage atm). The layout will...

Thanks both. I must admit I was considering using some, but it's not that easy to get hold of. I looked at the Marley dBlue, and the Wavin stuff as well. Does it make a significant difference? Was going to shove some dense (60kg/m²) acoustic slab wherever I can around ordinary pipe, but would...

I'm trying to find a solution for replacing a Saniflo in an ensuite bedroom. It's a biggish, late Victorian house, and I need to get the soil pipe from the front to the back of the house. I can run the first part of the pipe in the floor as the joists run the right way, but for the second...

So it would be acceptable to have a run longer than 6m if I fit an AAV, or, I guess on the basis that an AAV might be insisted on, I could extend up through the roof and vent it? Neither would be a particular issue as work needs doing on the roof anyway, and probably even easier to fit an AAV...

Many thanks for the speedy replies. I was at the house yesterday, and checked a couple of things. Firstly, the 3.7m is the distance to the back wall, not the angled length, so that is actually about another 500mm long (who knew trigonometry mattered), and I neglected to include the distance...

The title says it all really, how acceptable is a change of direction on a long horizontal run of 110mm pipe? I want to create an ensuite in a house I'm working on, but unfortunately it's going to involve getting the soil pipe to the stack at the back of the house. About the only way I can...

Are you psychic? Just measured the current flow rate and it's 20.5 litres per minute (filled a 12 litre bucket in 35 seconds). Also tested the pressure using a basic mains tester gauge, which gave a reading that settled at about 4.8 bar. It would drop down to 3 when I flushed a toilet that is on...

I'm going to upgrade the supply pipe to the house as it's currently lead and it won't cost a fortune, especially as the house fronts onto the pavement. I was going to go with 25mm supply, but maybe 32mm would be a better option. The house is to be gutted so I can run 28mm (is there a practical...

That's reassuring, I suppose I'm accustomed to combi's these days and my memories of hot water tanks are back when I was a kid and the roasting hot airing cupboard with the red insulation jacket around the cylinder which was far removed from what's available these days. Final question, rather...

Thanks for all the feedback so far. To be honest, I'm more looking at trying to boost a combi that would be marginal at supplying 2 showers to one that would better supply 2 showers. In my own home I'd go for a different system, but in a rental property, where I'll be footing the bill for hot...

I certainly wouldn't look to heat the cold water supply to anything other than the shower, if that were even possible, and definitely not to any bathroom or kitchen taps.

Has anyone any experience of shower heat recovery systems such as Showersave/Recoh-vert or Ecodrain? In particular, are they good enough to boost a combi's DHW supply sufficiently to cope with 2 decent showers at once? My thinking is kinda as follows. If an ordinary boiler has a stated output...

We have an arch on a hallway under a staircase, and, while it looks nice, we need to fit a fire door there somehow. The top of the arch is a touch less than a standard door, so we can't square off the arch with a door below it or only very short people would be able to get through. I'm sure a...
