Is a ping pong ball the best ball to see flow inside a strainer with see-through lid

[Leighb]

I never came across a strainer where you can't distinguish if the water is flowing or not, with just a bit of practice.
I mean, also when there's nothing inside it to emphasize the water movement.

You have obviously not encountered the VP design which has a black top? Impossible to see through! In addition I have underwater exhausts so a quick look to see if water is coming out doesn’t work either.

A ping pong ball and deodorant ball are both very light so will sit right against the top of the strainer. I think I will try and print a sphere with a density so that it stays suspended in the water.

A plastic wine cork?

Harken do a strainer ping pong ball. It’s identical to a normal ping pong ball but has Harken written on it. £299.95 from all good chandlers. You’d be mad to use anything else.

I have tied a short length of red ribbon to the handle of the strainer, it really shows the water flow.

Both the engine and the genset have a water separator.

All well and good, that's a very common solution.
But technically, it still is a wet, not a dry exhaust.
Which is how you called it - hence my surprise.

By the way, what are to day ping pong balls made of?
I remember a few centuries ago they were of celluloide (English translation?) and, when dented, one refurbished them by dipping them in boiling water.

We used to warm them up to expand the inside air to push out dent

Since 2015 they have been made of a plastic polymer, prior to that from celluloid (like old movie-film stock, and equally inflammable).

Thanks Alan,
I expected celluloid was no more used. Together with Bakelite, it was one of the first man made stuffs used in a time when anything was made either of wood or iron. I can remember its smell.
