Build a Recirculating Draft Line Cleaning Pump + New Safecid Beer Line Cleaner Review (toward end of review)

Clean kegerator lines are a key part of serving delicious beer. Bacteria and mineral build in lines can cause off flavors, quick loss of head, under-carbonated beer due to rapid co2 loss and lack of legs forming on the inside of your beer glass.

Limited Time Deal:

Helps you clean multiple lines at the same time…

Valuebrew is offering a pack of two jumpers and 25 replacement o-rings for $32.97. Coupon code JUMP discounts the combo by a whopping 32%.

Double Jumper Special! < note that you must use this link along with coupon code JUMP to get the deal, the standard product will not get you the discount

Valuebrew’s jumper is unique because of the custom color, food grade o-rings and because … it works with both liquid and ball lock jumpers.

The directions on most line cleaners call for recirculating the cleaner for some period of time. Most affordable cleaning setups that are out there include a hand pump. Operating one of those for 15 to 30 minutes, for each faucet, doesn’t sound fun.

To really clean your draft lines, you need to keep solution flowing for a length of time, not just fill and wait. Initially I tried to clean my system by pushing line cleaner out of a keg. This was a waste of CO2. I also found it tough to keep solution running slowly enough to get the required amount of contact time. It’s easy to quickly push a cleaning or sanitizing solution through your system under CO2 pressure, but I found it to be a pain to try to do so slowly. This also requires quite a bit of cleaning solution versus a recirculating pump.

I decided to put together a recirculating draft line cleaning pump setup.

One of the questions that arises on these type of carb caps, is… does it work with both liquid and gas posts? Some models are universal fit and some work only with gas posts. For draft line cleaning projects to work well, at least in my opinion, the carb cap that’s used needs to be universal. I’m happy to report that the one I received did indeed work with both liquid and ball lock posts. Check product description for current specs.

Make a ball lock keg out out of PET plastic bottles. Great for taking beer to a party or making your own mini keg system with a 2 liter soda bottle.

This tee piece enables you to attach both a liquid and gas ball lock disconnect to the bottle at the same time so you can essencially use a common PET bottle as a keg. Very handy with a two liter soda bottle, as you can get a short length of ¼” interior diameter silicone tubing, attach it to the top Carbonation Cap (not included), fill with beer, and put in the refrigerator, either upright or sideways.

Or if you have Nukatap or Intertap faucets on your draft system, make a draft system cleaner – fill a soda bottle with beer line cleaner, attach an optional ball lock adapter to the end of your Intertap/Nukatap Faucet, and open the faucet to force cleanser into your draft beer system and down the lines.

Note: This is for the tee piece only. You need a soda bottle with standard PCO 1881 thread, 2 item C35 Carbonation Caps, and some ¼” interior diameter tubing to complete your soda bottle keg conversion.

This tee in conjunction with compatible carbonation caps can convert PET bottles into mini kegs or for use flushing or cleaning draft lines.

A great deal!

Building a Simple Ball Lock Draft Line Flushing Setup

I use a recirculating draft line pump for cleaning my draft lines. That’s worked well for me (and many others) for years. See: Recirculating Draft Line Cleaning Pump

The issue I ran into was the desire to periodically do a quick flush to rinse, clean or sanitize lines.

When a keg kicks, there’s residual beer in the line. The beer at the end of a keg is also more likely to contain gunk – hop and yeast trub. Rather than leave that sitting in the line, shank and faucet, I like to flush is out. Also, when putting on a new beer I wanted to be able to easily sanitize.

Of course, I could get out my complete keg line cleaning pump, but setting that up and cleaning afterwards is a bit of work. What I wanted was an easy solution for a quick rinse or flush.

v1 of this build dates back to 2013. A little about that, for comedic and nostalgia reasons, at the end of this post. This write-up walks through a much improved v2.

This build is super easy, works great and can be made from a few items you probably already have around or can easily obtain.

The components – a 2 Liter PET bottle, a carbonation cap and a short length of tubing. My build uses a Kegland DuoTight Compatible Cap and EVABarrier tubing. DuoTights and EVABarrier are outstanding [Hands on Review], but I want to stress that these exact components are not required. Any suitable carbonator cap and a length of compatible tubing should do the trick.

Carbonation Caps:

Stainless Carbonation Cap with 5/16″ Barb Ball Lock Type, Fit Most Soft Drink PET Bottles
UP100 Line Cleaning Cap Stainless Carbonation Cap Counter Pressure Bottle Filling,w/ 5/16″ Barb
New offerings regularly pop up. Search Amazon for “stainless steel carbonation cap” to see what’s out there. Again, check descriptions to make sure these work for both gas/grey and liquid/black QDs.

Step 1 – take off the label. Or… leave it on. 🙂 Whatever you want.Step 2 – attach tubing to carbonator cap. I like the idea of using EVABarrier because it’s stiff and I thought it would work well.Step 3 – Trim the tubing to fit. That’s it… you’re ready to change the world by quickly and easily flushing ball lock lines!

Flushing Lines

This photo shows pretty much all the players. The left side is the gas line that I use for charging the cleaner assembly. The right line is liquid line with ball lock QD. You can also see the other side of the liquid line terminating in the right-most shank. My setup is all DuoTight/EVABarrier and you’ll see DuoTight Compatible Locking Clips used throughout. If you are a DuoTight user, the locking clips are something I recommend as they provide a more secure connection.

This is powered by CO2 pressure. It’s important to underfill the bottle to leave some head space for CO2 pressure. I found that about half full, or 1 liter works well. I used about 30 PSI of pressure. Make sure to choose a pressure that’s compatible with all components in your setup.

In Action!

This works really well. 1 liter (half full) along with a 30 PSI initial charge would be enough to briefly flush all four of my tap lines. Alternatively, less than 1 liter could be used to minimize chemical use. A “quick clean” could also be accomplished by filling lines with PBW and letting them sit, followed by a round of water and finally Star San.

The pitcher I’m using for collection is a 2 Quart Rubbermaid Commercial Pitcher. This is a smaller version of the one gallon pitcher I’ve used and recommended for years. Although I got this half gallon size for the kitchen, it’s worked it’s way to my brewing area and is the perfect size for this task.

But Will it Flush Two Lines??

Here’s the key piece of hardware to clean two ball lock lines at the same time. It’s a ball lock jumper from Valuebrew. There are only a couple similar offerings out there, to my knowledge. This one is unique because it uses their custom color, food grade post o-rings AND… it works with both liquid and ball lock jumpers.Here it is installed. This is connecting two 10′ EVABarrier tubing runs.If you look on the right you’ll see my Intertap faucet is equipped with a ball lock nozzle. This would work the exact same way with a NukaTap faucet. If you have another brand, you’d just make a jumper that fits over the spout of your faucet.Complete Setup for Two Line Test

The plumbing for my test is as follows

Flushing Assembly – 2 L bottle/carbonation cap/dip tube (on left) >
Ball Lock Line Jumper – 2 ball lock QDs with a short length of EVABarrier tubing >
Intertap ball lock spout on right faucet >
10′ EVABarrier tubing with ball lock QD >
Ball Lock Jumper Fitting >
10′ EVABarrier tubing with ball lock QD >
Intertap faucet (second from right) >
2 Quart collection pitcher

In Action – 2 Lines!

I was actually quite surprised at how well this worked. It’s over 20′ of tubing, four QDs and a jumper. All being driven by the head pressure in half of a 2L bottle.

Super Size It

Kegland makes a 2.5 Liter PET Growler Bottle Growler that gives you some additional capacity.

Alternative for Pin Lock Systems

The setup outlined here is for ball lock systems. I know of no similar Pin Lock carbonator caps or fittings. You could build as outlined and make a small jumper to go from Lock to Pin Lock

For Fun, Here’s More about V1…

This setup also uses a PET bottle to store solution, but gets more complicated and… harder to use from there.The cap was modified by installing a Shrader valveInside of the converted capFrom there, I put together a bunch of relatively expensive parts to form the ball lock connector

To make it harder to use… there’s no dip tube. The bottle had to be oriented so the top faces down.
