Waste Collector Pressure question

[mr_alberta]

Hi,

I was wondering if anyone knew roughly how much pressure needs to build up in the waste collector and skimmer before foam production shuts down? Would it be enough to pop out push fittings or anything like that? Dumb question I know but I don't want my waste collector blowing out a fitting and spraying skimmate everywhere.

The shutoff valves are just a ping pong ball that push up against where the drain line empties into the waste collector.. If I put my thumb over the drain line of my skimmer, I shut down the foam production and I don't feel a thing. It's not a lot of pressure.

Thanks Tony. That's what I thought as well, but just wanted to make sure and double check.
