Where can I get a one way checkvalve for a smoke system?
Make one real easy.......use a GP fuel filter, ball point pen spring and a large BB or Ball bearing.
Cut spring in half, open fuel filter, place ball bearing and spring in filter, close filter.
Presto! one check valve. You can vari the pressure by the lenght of the spring.....experiment.
My wife lost several pens before I got it right.
