Yeastmeister when you right your right
here's the replay from the hop stopper people
Thanks for your inquiry. The performance of the Hop Stopper is not really dependant on the use of pump. However, the issue of cooled vs. hot wort does have bearing. When using an immersion chiller, the resulting cold break can, but not always, clog the screen. As I said, this is not always a problem, but it does happen occasionally. Whenever these occasional problems arise in the use of the Hop Stopper, it is invariably tied to the use of an immersion chiller and the resulting cold break. There are some steps that you can take to minimize the effect of the break, one of which is to slow down the flow rate as the kettle empties. In gravity systems, this slow down is automatic, but when using a pump, this needs to be done manually.
Over the course of selling hundreds of Hop Stoppers all over the world, there have only been an handful of returns where homebrewers simply could not get the Hop Stopper to work. In every case, I have refunded the full purchase price of the product (including the shipping cost) and arranged for the return shipping of the product at my expense. This is the best guarantee available for any product on the market.
I hope I have answered your question adequately. If you have additional questions or need further information, please contact me.
Sincerely,
