Pitless adapter

[Shaun]

Has anyone used a pitless adapter to install a submersible pump in a vertical extractor? I have a 30" simple vertical with an external pump that works good to 22" inches of vacuum, hoping to go higher and have a spare.

I have not tried a pitless. I added a second dump valve to my mechanical with a Uniseal. Seems to work fine with 27.5" this year. MES uses them for their releasers. I have purchased them on eBay.

In theory a pitless adaptor would work. but since most of them are brass it would be bad to use in your releaser. Like Wiam said a uniseal would work better.
