Motor impeller forms air lock, have to wait for incoming water to
catch up, using shortest run with ID tubing to match pump.

Why does it need to be slowed down?

My Jabsco toilet pump needs to be slowed down, what is the simplest
way to reduce speed, by voltage? It also is very noisy, hopefully
reduced speed will quiet it down too.
