It really is pretty incredible that this sink can flush a shovel full of dirt! I think one reason for the 6.5 gallon flush on these sinks is just because they might be used to flush much greater amounts of wastes than what we flush in a toilet from a single use. It's possible that even buckets of wastes (not necessarily human) get flushed in some service sinks.
That thing is sweet! Toilets with concealed priming jets can struggle to flush heavy solids like rocks because they sink to the bottom of the trap and they are out of the path of the jet. In one of my Kohler Kenwyn videos, I flushed an old ball of plumbers putty that just sat at the bottom of the trap. All my exposed jet toilets will flush it, but none of my concealed jet toilets will.
Hospitals and morgues use them for flushing bodily wastes from bedpans and autopsies. Sometimes they are in campgrounds for disposing dish water and food scraps. The square bowl is much more convenient than a toilet bowl for dumping buckets and such. Service sinks are also designed to flush 6.5 gallons per flush.
When I worked in the ER, we had several of these service sinks. It's more convenient than a terlit since the bowl is wider, longer, and deeper. In addition to body wastes, body tissue, bedpan wastes, foods that don't need a garbage disposal, liquids from wound washings, old wet wound bandages, pliable paper, TP, which paper towels, IV bag contents, Rx, blood, small sponges, gauze, etc. You get the idea. Plastic tubing goes in the trash and needles go into sharps bin. Short pedestal sinks are usually mounted so the top of the sink is anywhere from 24" to 40" above the floor, but never on the floor. They are always on a raised base with sewer pipe access, like a baby Devoro on a pedestal to raise it up a little. They have terlit pedestal type sinks designed to be bolted to the floor. I never have seen a wall mounted service sink until this video. So they are rare. The morgue is a little different. They have both service sinks and terlits, one each per 2 stations. No seats on the terlits. In addition, they have a SS countertop with a big SS "farm sink" type built in with a commercial garbage disposal, one per station. I'm sure you've seen the famous "Dr G." autopsy series on TV. Gives you an idea. Her videos are also on the net.
This is such a cool thing!! I have never seen a sink that can take a washcloth before!! Obviously it’s not built for taking washcloths, etc, it still done great nevertheless.
Interesting! Thank you. At Habitat for Humanity ReStore I boughthisame clinic service sink to mount in our garage. Shall plumb it into thexisting 3" PVC waste line from the powderoom toilet. *What ring seal do I use?* Should not have failed to flush outhose cloths. The dirt clump should not have remained. Appears the rim holes in the center of the rim will need to be a little bigger. Can you file those holeslightly larger? (Manyears ago I noticed that my girlfriend's toilet was not flushing well. Since 1966 mineralslowly building up from water evaporating in the holes was restricting the water coming out. Using white vinegar I manually removed the minerals. Toilet flushed like new - using too much water as 1966 toilets did. Should be replaced with a water-saving toilet.
I have a request for you. At the rear discharge outlet, put a curved pipe going down so it will siphon. I have always wanted to see something like that. So if you still have this service sink, then please and thank you.
Would that curved pipe cause a little back pressuresistance? Also the plumbing code wants the 1-1/2 or 2-inch vento be close to the fixture outleto break anyacuum so that water remains athe proper level in the bowl.
Haha yea! I got it at my old salvage yard back when I lived in WA. I still haven’t gone to my new local restore yet. So Im hoping that when I go I’ll fine something neat!
That was impressive seeing that shovelful or dirt get flushed down, as was the distance that the water shot out of the discharge. Please keep your videos as they are, and talk all you want. I wish I could talk as well as you can while you're shooting videos. I'm finally getting around to editing the 3 videos that I made in 2020, and I have to cut out all my "bloopers".
