we'll ship a replacement gauge out to you right away."
Well, i guess we know what happened to @Big_D 's unit!!!


I picked mine unit up today from my "damn porch pirates forced me to rent a friggin' ups store mailbox".
This baby is HEAVY! Wow. Speaks to... well, i dunno, really... but my life experience tends to lead me believe heavier is better.

+1 to the Spike customer service.

Hope you get your unit soon Big_D!

My impression too. That thing has some serious heft to it. I'm also impressed with the machining, especially the fine tuning of the vernier adjustment of the spring tensioner. Just be careful with that pressure dump plunger. Even at just a couple psi, it'll give you a Star San shower. Don't ask me how I know.

Brew day complete, I was a little anxious and woke up at 5am and started my brewday, cf15 filled with new prv resting atop in all its glory.

I'm interested in your setup. It looks like you have a blowoff tube and the PRV installed at the same time. I was under the impression that the blowoff tube stays on for a few days and then switch it out to the PRV

I bet he uses that butterfly valve- he closes it on the blow off line. Then no oxygen exposure by having to switch clamps.
Insert warning- always ensure you have a clear clean dedicated blow off PRV before adding a valve!!!

Got the PRV, can't wait to use it on my next batch! I had one question for @SpikeBrewing though. I noticed that if the airlock/cup is filled with water or sanitizer, and you depress the plunger, the liquid drains through the holes down into the fermentor. How are you supposed to relieve pressure in the vessel without letting liquid in?

You’ll want to pull off the red and black cap to drain the sanitizer cup.

So @SpikeBrewing … how‘s that “testing” going? 🙄

Per the email response quoted below, I was told last week that my order “should“ ship out this week. Haven’t heard anything and this week is just about over?


"I'm sorry but there has been a slight delay in our testing process with these. We should be shipping this out next week! Thank you for your patience here."

I’m with our marketing team so I don’t have real time insight on quality testing. Have you shot our Support team a message to see what’s up?

I just got one of these last week. The build quality and idea are great. However, my concern is that starsan in the sanitizer cup can leak down into the fermenter. I've had to top off the sanitizer cup twice now & I highly doubt it's due to evaporation.

I haven't had that problem (leaking) at all. I do suspect it may be due to evaporation, however. The surface area of the Spike unit is quite a bit larger than the surface area of my SS Brewtech spunding cups, as well as not as deep, so surface evaporation may likely be greater. They also need to be topped off maybe once or twice a week, and they aren't leaking into those fermenters. I do like the Spike spunding valve, but I do have two minor gripes. First, it's pretty tight quarters trying to get a drain cup in place while removing the red/black nipple cover. And second, I wish the liquid cup was taller/deeper to hold more volume to keep the release holes submerged longer between top-offs. In winter months when my brew area humidity level is low, if I'm gone or out of town for more than 3-4 days, I have to worry about the limber holes not being covered with StarSan or water. Otherwise, I'm completely happy with the operation and safety the Spike unit provides.

I agree with both of your gripes. I really hope starsan isn't leaking into the fermenter though. The only thing I can think of without having access to the innards of it is this: perhaps the pressure plate (or whatever it's called) that pushes up when CO2 accumulates distributes unevenly. I noticed that the holes on one or two sides might be bubbling while another side is not. Perhaps the side not bubbling is allowing some liquid to drain down since there is no gas pushing out that side of it.

The seating of the plunger gasket is pretty good, and the overall machining of the unit is very good. The asymmetry of the bubbling pattern could also be due to the unit not being perfectly square with the plane of the earth (gravity), especially noticeable if the bubbles are very small and releasing very slowly. Think of holding your breath underwater, tilting your head slightly and slowly releasing bubbles through your tightly pursed lips. The bubbles would only be visibly present on the higher side of your mouth. I've seen the same phenomena on my Spike and other spunding cups. When fermentation is vigorous and bubbles are being released faster, you don't notice the release asymmetry pattern of the bubbles due to the high volume of gas being released.

Obviously there could be some leaking into the fermenter, but I think you'd see some deformation of the spunding valve if that was the cause. Now if the unit has been dropped that might be a different story. Is your fermenter on a flat surface? Even a poured concrete basement or garage floor is going to have some barely perceptible slope. Even just a few degrees of out-of-bubble level could cause what you're describing.
