Hudson Perfection Pumpless Model 21432 Schematic And Help

Question From: J. Hardy - ALASKA
Q: Hello. I have a Hudson Perfection PumpLess Model 21432. Is it possible to get a schematic for it? There are three valves on the top. One is for escape, another for attaching the pump, and the other of which I am unsure. I need help. Thank you so much.

A: I recommend you contact the company that manufactures this product for this information. Also request a retail company that sells and services these products in your area that may also be of help. Best And Happy Yardening, Nancy.
