Why don't kitchen sinks have trip lever/plunger drains?

[AndrewP]

I've seen many sinks plumbed where one waste pipe has a sharp 90 that drains into the waste of the other sink. I know it's best to have the least amount of pipe before the p trap, but this is fairly common.

Just wondered why I've never seen a bathtub style trip lever/plunger drain or standing waste applied to a kitchen sink. Would seem very useful when you want to drain a sink with filthy water as it saves having to put your hands into the water.Something like this:

Is there a reason why?

I suspect the linkage could get impacted with food waste. A bathtub drain deals with hair, but not food residue.

Commercial sinks sometimes have that ability...haven't seen it on a residential kitchen sink. https://www.plumbingsupply.com/fisherwastevalves.html

My sink DOES have remote operated drains. You just need holes in the sink for the push/pull knobs.

Those commercial ones linked to I think are butterfly valves. Interesting design, that would impede water-flow less than the pop-up ones you get on bathroom sinks. These seem to clog all the time.

Hj, what method does yours use?

On clogging, the standing waste design, would seem the least likely to clog in theory.

Which of these would work better? The first is pretty standard standing waste, with p-trap. The second attempts to reduce the exposed pipework. These are not to scale. Basically the difference is the bottom of the second waste/overflow (in brown) is underwater. Any thoughts?

We install hundreds of Franklin wastes Unfortunately many are now imported and are crap

Mine are cable operated with push/pull knobs on the sink deck. My sink has six holes so it has the faucet, steaning hot, cold drinking water, two drain operators, and a soap dispenser.

Notice the cap on the Franklin opposite the handle? That is for an overflow if the sink has one

The problem with an overflow on kitchen sink overflow is the possibility of bacteria growing near food preparation

This is why expert witness can work the legal system on both sides either way you're doomed if you have to defend an action in court

No overflow a good chance of spillage causing a fall , with a overflow great change of E - coli

ALL "expert witnesses" have to check who they are working for because they ALL can work for either side.
