P-Valve backflow

[Randy43068]

It's getting to be an old thread, yet it's still relevant.

Having said that, what kind (brand) of P-valves are you folks talking about? Halcyon was mentioned, so is this the valve at issue?

Is the check valve something available from McMaster Carr?

Thanks!

The duckbill can have funny things done to it if you're not careful with what you use to flush it out.
