How to install a vacuum gauge?

[catnip]

Could you clarify the part about the "1/8 female pipe thread"? is this a pvc fitting that you screw into the hole you drilled?

I used a 1/8 inch brass nipple (female threads on each end) to screw into the tapped hope in the PVC. But, as Poconos says, you can try tapping a 1/4 hole and avoid the need for a nipple and 1/8 - 1/4 brass coupler.

Thanks Catnip...I think I'll screw it in straight into the pipe...but I'll practice first

Do I have to use a "liquid filled gauge" or a "dry" gauge will do the job? http://www.recreonics.com/standard_gauges.htm

Thanks again

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!
