i cut my pressure switch off to fit varistream
Is that right?
Yes, the Varistream was designed to bypass the pressure switch and you set the pressure electronically.
The only thing that this controller does is slow the pump down. It doesn't regulate the pressure from what I see. So in my opinion this controller will just let the pump keep on running if you didn't put it through a pressure switch. I would have to conclude then that this pump would build up pressure and eventually stall and burn itself out or blow one of the hose connectors off.
I don't want to slate this person's efforts, but I feel that he has come up with an idea to make an analogue controller because so many are having problems with the digital ones. I don't believe he actually understands the concept behind how a controller works. It would then appear to me that he has 'borrowed' some of Spring's wording for his advert. (Connected to a pressure switch will add further protection).
I'm all for guy's coming up with new and innovative solutions to make our job easier, but I don't believe that this is one of them.
I see that he sold a Gardiner Eco Flow controller on Ebay that ended in the 19th of Jan for £17.01 with £2.00 postage. Not sure what happened but the listing was ended as he received his right price???
He had also been using that controller for more than a year with the same pump and was very reliable. So he's been using 2 controllers for a year that have been very reliable.
This controller has to be used with the pump's pressure switch IMHO.
