haven't delt with alot of vessel sinks, doing a reno at customers house a mobile he complains how sink drains slow,i check the line is not vented,tell him it should be vented properly,install a vent and new trap,had also replaced line earlier under trailer so i know its not blocked.watertest sink and it is still slower than sh**t , sink has a strainer with the little holes in it. is it possible it is air locking due to the fact the sink doesn't have an overflow? has anyone delt with this and what was the solution.

Not only is it common, it's guaranteed. It's well known that grid strainers for lavs or vessel sinks have this problem.

Switch to a pop-up assembly and problem solved.


It's always an air bubble trapped under the grid. If you rub your fingers over it fast the bubble will pop and the water will drain normally.

Kinda defeats the purpose of washing your hands though...:blink:


I'm setting 2 this wednesday, they are unique for sure.

Either that or sell them on the push button style, like this one:

Hate those vessel sinks! From an install POV as well as a HO POV.
Especially the really thick ones that no PO on the planet will let you thread on the nut to the bottom.

A friend of mine told me he once had to take a belt sander to the bottom of a vessel basin, just to get the tailpiece to grab...

I'm partial to the Flip/Roll Top drain assemblies for vessel sinks lacking an overflow.

Much more open surface area than a pop up or lift and turn drain assembly.

Drill out the grid style ones, use a slightly larger drill bit and just drill each hole out a little larger. Can't even notice it was drilled...

Wait, wait, a vessel sink in a mobile home?! Isn't that like putting lipstick on a pig?

Who makes it and where do you get it?
Sonoma Forge makes a version of it that is available in most finishes, I have never seen a difference between it and lift and turn drains as far as drain speed. We almost always installed vessel sinks with a counter mounted pop up assembly unless the counter top was made of glass or glass tile.

Sorry, but that's just asinine.

And here's why; Most vessel sinks don't have an overflow, whereas most, meh, **** it, all "pop up assemblies" are designed for lavatories with overflows.

As far as drain speed goes, it doesn't take a Rocket Scientist to understand that less surface area equals less time to empty the vessel.

The picture you posted is also for a sink with an overflow is it not? Most of the vessel sinks I have put in come with the drain assembly and the nut and washer at the bottom actually hold the sink to the counter top so you most likely can't just make any old thing work.

Good catch. The Roll/Flip top drain assembly is available with or without overflow cut-outs.
