Hi all - I got a new Hop Stopper 2.0 and brewed 2 weeks ago with it and had no issues and am happy to report that it worked like a charm on Brew #1! I brewed yesterday for Big Brew and I noticed that the flow rate into my fermenter went from what I would expect (slow trickle) to barely dripping. It took over an hour to fill at this rate. I noticed my hoses looked crushed as well, so I thought they were not being fed properly. I took my mash paddle and tried scraping some hop matter (4oz in a 12 gallon batch) off of the Hop Stopper 2.0 and still did not get an improvement in flow. I decided to ride it out at this point - which may have been a mistake. Once the kettle was drained the hops were caked on so hard and dry they reminded me of a thick felt. This is when I noticed the Hop Stopper was absolutely crushed flat like a pancake. I'm guessing the pump was pulling so hard for wort it collapsed the mesh.

I was not watching the system when all this happened unfortunately so I don't know if something happened to cause this.


I read the instructions and the Brew day step-by-step to make sure I wasn't doing anything I wasn't supposed to.

Anyone come across this before? Is it possible to fix it to get it to pop back up? I imagine the heightened profile is important for flow. I can get pictures if need be.

Hi!

I've asked the Hop Stopper manufacturer to chime in here as well, but I had this happen once during my fast flow test of the Hop Stopper 2.0. It's an easy fix: Use the handle of a wooden or plastic kitchen spoon inserted through the grommet. Just use the handle to push out the indentations. Takes a minute or two to do. Cheers!

I wasn't able to pop them out - they seem like they are creased. I tried a chopstick, wooden spoon and a long screwdriver but the screens are almost creased to the point of no return. I think I'm going to have to toss this one.

Creases are fine - you can definitely pop them out as it's stainless mesh - it can always be bend back. You just need to push a bit harder, bend further to get it to bounce back into it's normal resting place. That's what I had to do when I collapsed mine during testing. There's no reason why it wouldn't work. You can also email the manufacturer at HopStopper@TheElectricBrewery.com for assistance - they're extremely responsive.

I have tried everything on this and no luck. I'm going to toss it and get another one. Thanks for the assistance!

Hey, Dennis Collins here, manufacturer of the Hop Stopper 2.0. Shoot me an e-mail at HopStopper@TheElectricBrewery.com and I'm sure we can work something out.

I did want to post an update on this - I spoke with the manufacturer and we went over my process and we think what probably happened is that I was pumping the wort out too fast which sucked the hop matter onto the screen. He did recommend whether you are whirlpooling or pumping it through the chiller, no more than 1 gallon per minute should pass through the screen.

Thanks for the update!

Keeping flow under 1 GPM at all times is best. It's what's recommended on the Hop Stopper order page and in the manual. Just to be safe.

Cheers!

Kal - When I read the manual, I took the part about keeping the flow rate at <1 GPM only when whirlpooling. My mistake on this.

Any flow through the Hop Stopper should be limited to 1 GPM (max). The Hop Stopper doesn't know if you're recirculating to whirlpool or dumping through a chiller into your fermenter, or spraying your kids with hot wort (Wink). It doesn't understand the difference - All it knows is that it's flow through the Hop Stopper screen.

1 GPM is pretty fast. For example, that would be like trying to chilling 12 gallons of boiling wort through a chiller to the fermenter in less than 12 minutes.

I was able to brew today and I changed things up as recommended and it worked like a champ. It was definitely my fault on this one.
