Pipework Behind Kitchen Units

Recommended Posts

We have waste pipe that would be very difficult to re-locate along a wall where we have a run of new base units, there are also heating pipes which is making the whole thing protrude from the wall around 80mm, my fear is that we will struggle to fit in the integrated oven that is 550mm deep, has anyone got over a similar issue?

Can you move the base units a little further from the wall? There is no hard/fast rule about where you position them as long as this works in the room layout and you can get a worktop deep enough to accommodate.

Thats possibly my best option, we are having quartz worktops which will be cut to suit so would just mean that that worktop would be slightly deeper.

Can you make them lower - without seeing the situation it is hard to know for sure, but pipes can be run under cabinets for sure - just depends on other aspects how difficult it would be. 

 

If waste goes through the wall then that is an issue, but if through the floor or at floor level that would work, or core new waste hole at floor level etc.

 

Can you post some images of the location/pipes.

80mm is a lot - what size are the pipes?

 

Most kitchen units have a service void that will easily accept a 40mm waste pipe.

 

Post some pics and measure the pipes.

I think he has to pass heating pipes, so by the time you take the 15mm heating pipes, their brackets and the waste pipe to pass that, 80mm is feasible.

 

Moving the units forward is the practical solution for sure. I'd build the whole run, screw them all together, position them to miss the pipework, level the whole lot then contort something to attach them to the wall. Simples.

This is almost exactly the situation, there are 25mm heating pipes on brackets with the 45mm waste in front. I'm going to see if I can get the waste any lower so its beneath plinth level but I don't want to lose the fall on the pipe. Not sure if a small Saniflo would be of use if I did that.

 

I might do as you say then maybe screw a timber to the wall to fix the units to.

My wife had already decided she wanted 750 deep quarts worktops

Which helped me with the fitting I simply ran the wastes a pipes on the surface and fixed two 50 mil timbers to the wall 

Which gave me a 100 mil service void

I had to do a similar thing behind my washing machine, wasn't my favourite piece of work to be honest, but good luck.

That looks pretty good to be fair, you didn't get your units from DIY-Kitchens by any chance did you?

Can you run the waste along the floor and up into the cupboard from below instead of behind. 

You normaly have 150mm to play with under a unit. 

 

Got any pics.

My brother inlaw had a Plummer fit pipes in his kitchen, then got me to fit his units but they had only about 25mm as a void (can’t remember where he got them), luckily the wall was thermalite blocks so I chiselled the wall away and buried the pipes into the wall.

As previous posts, just do deeper worktops. Luckily, appliances these days chuck the heat out of the front. 20 years ago, an oven up against a plastic pipe, would have resulted in a melted pipe.
