Drainage issue

[Riley]

Hello all


I have been asked to quote to improve drainage at a property.

It would appear that at some point in the past the layout of the downstairs of the property has been switched around taking the kitchen to the back and bringing the lounge and dining room to the front. Whoever did the kitchen install has done an appalling job with the waste pipe and has run best part of 15m of waste pipe in 1.5" with not much fall. obviously I know that this length is ridiculous however the only soil pipe is at the front of the property. In addition about 8 m of this pipe is hidden behind kitchen units.

Now i'm not looking for a bodge here but I'm just wondering if I have any alternatives to pulling out all the kitchen units and re-piping and obviously upsizing the waste pipe accordingly. My gut feeling is there is no sensible way to do it other than having the entire kitchen out. I did mention it to RPM in the hope that there might be a pump suitable but it would appear not.

Any thoughts would be massively appreciated many thanks Matt

I was going to suggest a saniflo, not sure how far you can run the pipe to drain after though. Could you extend the 4 inch externally to nearer the kitchen?

I thought Sani but I think it's going to cause equal destruction doing that. Pipe runs back to front of property and it's a terrace so no external option

Is the issue that its blocking up at the moment?

If it all runs internally then any option will be destructive.

Saniflo used to claim 50m but in reality it`s all about gravity. The problem Riley has is the fall of the pipe so I advised accordingly as in I wouldn`t like to put name to it. However if it was done some years ago and the pipe doesn`t block up then on reflection a Saniflo is an answer but advise the customer of the pitfalls in going down this route.

Here for you Matt if you want to discuss this again.

Surely if its going through a macerator first then its better than just coming straight from a kitchen sink, which food etc is more likely to go down in bigger chunks and sit inside the pipe due to not having enough fall? That would be my theory anyway, I could be wrong.

Cheers mate appreciated. It doesn't block but drains slowly. I will give you a shout
