How to best relocate this waste pipe?

[budest]

Hi guys,

I removed a kitchen unit that was designated for an additional appliance. I intend to install a full-size dishwasher and whilst the dimensions of the space are correct the waste pipe will push the appliance too far out into the kitchen. To the left of the waste are the pipes coming up from the floor to the combo-boiler. This is a ground floor location in a house.

Have any of you encountered such a situation before and if so, have you any advice?

Thanks

You could possibly just remove the blank and blank it off at the fitting at the bottom. You have a dead leg water pipe, which you also need to measure from, not the wall. Do you have a sufficient waste for the dishwasher?

I need both the waste and the water pipe, but I will be able to work around and adapt the Hep pipe as needed. With the waste being more a fixed object it was that that was my concern. Sorry that I wasn't clearer in my original post.

Yes, but you said you have waste pipes in the adjacent cupboard, so could you use that? I can see something sticking up from the floor in the corner. If not then it’s likely the dishwasher will have to stick out.

You mean this? "To the left of the waste are the pipes coming up from the floor to the combo-boiler." I do have a spare spigot at the waste under the sink which is adjacent, but I didn't mention that but you've given me an idea to just extend the waste hose from the appliance to under the sink and then to cut the waste pipe in the photo and replace the blanking cap. That would work. The appliance pumps out any remaining water at the beginning and end of any cycle so that would ensure no residual gunk was drawn into a new wash that was maybe lying in the extended waste hose.

Also, I note from the technical specs for the dishwasher that there is an ingress of 120mm in depth and 45mm in height at the bottom rear of the appliance that may allow me to modify the waste pipe and still use it.

Either way, knowingly or otherwise, you've helped me out - so thanks!

Correct.

Great, happy to help

Waste is far too low to be used as is .How do you plan to connect to it?

Waste in floor in photo would also need a trap so, unless chasing it into wall and using a hepvo inline, your best bet would be to use a sink spigot but keep the drain hose up high... Not along the floor.

How wide is the unit space? Is it tight to 600mm? If there was extra width space then the waste could be run to the left then upwards to create a stand pipe. Normally a full sized freestanding D/W is ~ 600mm deep, so even with it tight to the wall, without any pipes it will be extending 60mm beyond that kick plate.

I'm a little bemused by the size of that space as it doesn't seem to be what would be considered as a standard depth - usually cabinets/units would be ~ 500mm to the back panel and then another 70 odd mm behind as a service void with a standard worktop depth of ~ 600mm. The 70mm usually being plenty to get a standard appliance in and have the services behind and a 30mm extension out so can be inline with the worktop. That being said usually units would have the depth adjusted out to 600mm if they were to take a full size D/W - W/M - Fitted oven etc as they normally comes as 600mm deep

I know that doesn't help you here but I am surprised that the kitchen wasn't setup that way.

ingress of 120mm in depth and 45mm in height

Other way about BTW - 48mm in depth and 120mm in height. A standard waste pipe is 40mm PP push fit and 43mm ABS solvent weld so even then that'll be tight.
