Looks a bit cheap to me.
Does anyone use something like this?

I do, on my pool.



I am having a hard time believing this is not a joke.

Nobody should have anything like this in a boat, especially not in a thru-hull. Lots of reasons given by other posters here. I once used these hardware store plastic valves for domestic water lines (between deck fill and plumbing to domestic water tanks). In every case the valve handles broke off within a year, in one case the housing exploded over the winter (even though lines were flushed with pink antifreeze in the fall).

Hoohaa, wish to take you up on slighting drinking hot tea on a hot day. It's what they do in India, or do you think drinking cold soda to be a better option? Condemning hot drinks on a hot day is dumb!

“Whoever did this has no business working on boats.”

Not true…
Somebody has to scrub the deck and sponge out the head! :-)

All attached hose nipples are threaded bronze and I would never use PVC cement , as I am not sure about the salt water effect on said cement..

PVC cement is actually a solvent [not an adhesive/glue] , that melts the surfaces of the PVC, chemically welding PVC to PVC [not to ABS nor Bronze]. In effect, PVC solvent cement makes two PVC parts inseparable.
Salt water has no effect on the cold welded PVC-PVC slip joint.
It's NOT used on threaded joints.

His knowledge about valves is probably as good as his knowledge about drinks
Most people who live in the desert (or other hot places) drink hot tea
Never seen them drink cold soda

Okay the OP has used the past tense. It is already installed.

So I think the best thing we can do at this point is encourage the person to exercise the valve daily. This type of valve will easily break and fail to close if there is any marine growth on it. Therefore, the thing to do is make sure none ever develops.

Then, when the boat owner tires of the daily task of exercising this valve, they may be willing to buy a suitable valve.

I can't add to the shock others mentioned about this installation. Regarding marelon vs bronze throughhulls, both are long lasting. We prefer marelon as it's non electro-conducting, meaning less risk of galvanic corrosion and punching holes through the hull if a lightning bolt finds it way down this path, attracted to metal.

The rule is "no PVC below the waterline". Not acceptable.
