Kitchen waste too high, is the only option to lower?

Draper - certainly not the best but certainly not the worst. Not bad for its entry level price range IMO.

I do however groan when I order something from toolstation and then only discover it is Draper once they hand it to me.

In terms of drilling the core, should I fit the new sink and trap first, find out where the hole needs to be and then drill it. I don't need to take into consideration any fall angle for the waste outflow?
Doesn't matter if you go a bit lower down, a couple of bends will soon drop the waste pipe from the trap outlet to the right level for going through the wall. I personally prefer to come through the wall lower down, it helps hide some of the pipework in the back of the cupboard, and means less visible outside.
 
There are ways but it would make a better sound job just to lower it.
I'd then use two separate Ptraps with W/M spouts if needed
 
One of these would help:


The half sink pipe can be reduced to nearly nothing, so the whole lot would be a reasonable amount higher.
Mcalpine stuff is much better. This would be my choice


If you do not have a drill machine, getting this one would be a safe bet as it has rotary action ( that is the ONLY mode you would employ for use when diamond tipped core is used) plus rotary hammer for drill in hard materials and rotary stop for breaking using chisels


Here is a core that you could buy but would also need adapters to fit above machine, hence it is suggested hiring might be better option. You are looking at spending upwards of £170 for equipment only

Trap by McAlpine is my choice as overflow is delayed as a blocked waste means the sink fill up. A standpipe allows the water to spill onto the floor wghich is quite common

Thanks for your reply. I'm going to have a ring around the hire shops and check their prices, but looking online it's going to cost me over £100 for 24hr, which makes the think I'm best purchasing something, as I'll inevitably need it again.

If I went with the two products you posted, would this be the adapter I'd need: https://www.toolstation.com/diamond-core-drill-adaptor-sds-plus/p62181

There's another adapter that includes a pilot taper, but it's SDS, not SDS+, so I don't think it's suitable: https://www.toolstation.com/diamond-core-drill-sds-adaptor-pack/p79014

I think I'd like a pilot drill, so I'll try find one of those individually.

While I'm doing this it seems the opportune time to drill an additional hole for a tap outside, so hopefully I can get those 2 holes done at the same time.

We went with a cheap single bowl replacement sink (https://www.tapsuk.com/caple-crane-965-1-0-bowl-satin-stainless-steel-kitchen-sink-cr101ss-p28342), it needed to be 965mm x 510mm. It comes with it's own trap kit:

But if this isn't suitable I'll use the McAlpine 1.5 trap kit (that's already arrived) and blank off the .5 feed
 
I guess you could stitch drill the hole and then knock out the rest? Tidy up the edges and fill?
 
You get everything you need with these 2 items - the core set has all the adapters and guide drill etc and the gun is all you need for an a now and again use
Yes - but for what you need it to do and if you're only lightly using it then this would do as equally as well - if you think you may have the need to use it in the future.

If you wouldn't use it again then hiring would be the cheapest, less wasteful, option
 
Is it really too high? Looks to me like someone's just made a "homemade" trap from some random fittings. Looks plenty of room below the wastes to fit a proper trap higher up rather than bashing holes through the wall.

In the image I took above, the waste pipe is as high as the first part of the trap. It was my understanding that if this is the case, the trap would be constantly full for the water to reach the waste outlet?

The waste is undoubtably too high to be effective. The sink will drain slowly, any additional wastes entering the system, will also cause the sink to backfill.
