How to install a vacuum gauge?

[Poconos]

Can't answer the question on which is best but both are cheap. I wasn't even aware of the liquid filled ones until a few days ago when someone posted on this forum. I'd go with the dry and see how it holds up. Just my cheap opinion.

If your looking to do a quick check. You could screw it into the drain plug on the strainer pot side of the pump. When your done just screw back in the winterizing plug. ( you may have to use a brass adapter to match the size up but you can buy that at a big box hardware store)

Hope this helps

imfignewton,

This sounds like a great idea...I guess the vacuum inside should be the same same as just prior to the basket right?

I will try this method first to avoid having to make a new hole in the system. I could even leave the gauge in there permanent since I don't have to winterize the pump here in Sac-of-tomatoes, California.

Thanks!
