Sourcing a Replacement Pump for Mark’s Keg and Carboy Washer!

The purpose built Mark’s Keg and Carboy Washer is… awesome. It saves on cleaning and sanitizing solution, it’s versatile, doesn’t take up a lot of space and it saves me time. It’s one of my favorite homebrew tools and it has been for years.  Check out my in depth Hands on Review.

Finding a Replacement Pump

The pump on Mark’s Keg and Carboy Washer is, in general, very reliable.  Mine has lasted, for years, with no issues.  According the manufacturer, most pump issues that do arise are resolved by cleaning the pump.  Having said that, it’s possible that a pump needs replacement.  Finding a replacement is a bit difficult.  These are not sold by themselves.  It is possible to get a replacement from the manufacturer, but you usually need to provide proof of purchase and they aren’t cheap.

I put the call out asking HBF Readers [Let’s be friends!] if they had found any third party pumps that work as replacements for the Mark II Keg and Carboy Washer and Adrian got back to me in short order with this recommendation. Thank you Adrian!

Here it is….

Lyqily 740GPH Water Pump Ultra Quiet 55W Submersible Fountain Aquarium Fish Pond Hydroponic Pump with 8.5ft High Lift, 5.9ft Two-pin Plug Power Cord, 2 Nozzles

A couple initial observations

  1. This is rated at 740 GPH.  It’s my understanding that the current version of Mark’s Keg and Carboy Washer feature 530 GPH pumps.  If all of that is right, this third party replacement has quite a bit more power than the OEM pump.
  2. The Lyqily 740GPH Water Pump is not an exact OEM replacement. I am not reading anywhere in the product description where they are recommending it for this use. This post takes a look at the pump and only tests to see if it is properly sized and threaded.

Kind of beat up from use.Side by side.  OEM pump is on the left.  They are very similar is size although not identical. The Lyqily is more narrow.Front view of the two pumps.  Again, OEM is on the left.  Again, very similar in size, but not identical.  The Lyqily is slightly taller.But is the threading right??  This is a big one. I think the OEM pump has 1/2″ NPT threads. With these smaller utility-type pumps, who knows what the threads will be. It’s rarely mentioned in specifications. I’m happy to report that the threads seem very compatible. If the threads on the Lyqily are not 1/2″ NPT, they seem very close.Another view with the pipe installed.Another view with the pipe installed.But does it fit? While not exactly the same size as the OEM pump, sizing is close. The pump fits nicely and seems close enough to the original to function well from a size perspective.The Lyqily installed in the Mark II basinSide viewWith CIP Spray Ball Installed.

After every use of my Mark’s Keg and Carboy Washer, I thoroughly rinse out the pump using the hose from my utility sink and then let it thoroughly dry.  This helps to rinse out any chemicals that may cause damage over time.

Size, threading and power all seem very good on this pump. Find another pump that works? If you’ve found something that works, send me an email with the details, I’d love to share with fellow homebrewers,
