Kitchen Sink Waste Height Issue With new Sink


Postby dazzathedrummer » Mon Sep 04, 2017 12:45 pm

Hi

I'm just in the process of fitting a new kitchen sink. The fittings supplied are giving me a waste outlet that is lower than the existing outlet pipe. I need to buy a piece to bridge the gap - but I'm just wondering if the outlet is too high for the trap - as you can see from the picture, the outlet is only a couple of inches lower than the sink itself.

Will this be ok or do I need to move the outlet (or buy different fittings that allow a higher outlet)?
(also bear in mind that I didn't have any problems with the old sink and the trap was maybe three inches higher.)

Simply Build It

Hi,

You could stick with the current trap and attach it as it is. It wouldn't cause in issue with the actual flow of the water.. however, you would have waste water stuck in the trap (the bit that is lower than the waste).

Alternately, you could buy a shallow trap? If you bought two of those and joined them by the waste trap by buying the separate components and connecting them yourself.

I'd probably do the latter personally.

Thanks for the reply!

I've now got it all connected up and the waste does flow away with no problems (also no problem with the dishwasher connected).

As you pointed out though - the waste does sit quite high up....about halfway up the two downward pointing pipes.

I'll see how this goes for a bit but may well have a go at your second option of having two separate traps. I've re-positioned the trap to go behind the outlet pipe since the photo, but even so, it's taking up quite a lot of cupboard space (which will probably mean that it'll get knocked quite a lot).
