Recirculating Draft Line Cleaning Build

Recirculating Kegerator Draft Line Cleaning Pump

The directions on most line cleaners call for recirculating the cleaner for some period of time.  Most cleaning kits that are out there include a hand pump operating one of these 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 enough 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.

First I needed a pump.  I have a utility pump that I use for various tasks around brewery.  I decided that that pump was too powerful.  I didn’t want to deal with foaming issues that I thought may be caused by the high flow this pump would produce.  I wanted something with less power that could slowly circulate liquid through draft lines.

After looking around, I settled on the EcoPlus-132 Submersible Pump.

EcoPlus Submersible Pump - 132 gph - 4.3 ft. max - 9W - 3/8 in. ID

It’s variable speed, submersible and it has a number of included barb sizes including a 3/8″.

EcoPlus Submersible Pump – 132 gph – 4.3 ft. max – 9W – 3/8 in. ID

Note that the current picture shows a slightly different pump from the one I have.  My guess is that that this is a stock image issue and that the current pump looks just like my pump.  Either way it doesn’t really matter as long as it functions the same way and has the same specs.

I picked up the rest of the fittings from Midwest Supplies.

Liquid Post
Standard liquid post to attach the pump to your draft line quick disconnects.  You may already have an extra one of these around.

Cornelius Plug Adapter – 1/4″ MPT
The liquid post screws into this.

3/8″ Barbed to 1/4″ FPT Elbow
Put some teflon tape on the MPT side of the Cornelius plug adapter and attach this FPT elbow to it.  Note: The design has changed on this just slightly since I put mine together.  Just a slightly different look.

This basically gives you a Corny keg quick disconnect post to 3/8″ barb converter.

Now you’ll attach a length of 3/8″ ID tubing to this followed by the included 3/8″ pump adapter.  As far as sizing the length of 3/8″, use enough tubing to allow your draft lines to reach the bottom of a bucket you will use for reservoir liquid.

Assembled

The only thing that’s left is routing the faucet discharge back to the recirculation bucket. I’ve found 1/2″ ID Silicone tubing works great for this. The size is perfect and the silicone is stretchy enough to easily fit on the faucet. It is a bit pricey, but you really only need a few feet of it, just enough to get from the faucet down to the reservoir bucket. I’m guessing any 1/2″ ID tubing would also work for this, but I can’t attest to it from experience.

This design cleans your whole draft system:
This design cleans the faucet, the shank, the quick disconnect and the tubing.  Some designs that I’ve seen have you removing the beer nut and placing the hand pump apparatus directly on the shank.  That’s some work disassembling and reassembling and it also skips the line and quick disconnect.

BLC solution after cleaning all of my faucets.  Umm… they needed cleaned I guess.  I recirculated for 15 to 20 minutes per faucet.

Flow Rate:
As I stated I wanted a slow, steady flow of solution.  Here’s a video illustrating what kind of flow I’m getting with 7′ of draft line.  The 132 gallon per hour pump is working great for me.

If you want a higher flow rate, I suggest moving up to next largest pump in this line.

EcoPlus 185 Submersible Pump, 185 GPH

According to the specs on that pump, that pump also has an included 3/8″ barb.

Also consider picking up some Beer Line Cleaner (BLC)….

Some Da Vinci 1 Tips  –

  • I clean the printer bed with a cloth and warm water first (as suggested in the directions) but then go a step further by completing a final cleaning with rubbing alcohol.  I picked this up from Make Magazine.  It doesn’t take much.  Several drops along with a paper towel or clean cloth do the trick.  This cleans off any residual oil and helps the model stick to the platform.
  • The printer includes a glue stick for helping to affix prints to the bed.  These are just standard UHU Glue Sticks.  I’ve found a thin even coat of glue works the best.
  • A properly calibrated and leveled bed is a big part of getting a quality print.  If your first layer is getting spread out, your bed is too high.  If edges are lifting up, your bed is too low.  I’ve found the built in calibration routine on this printer to be difficult and time consuming.  I started using Gap Feeler Gauge to do a manual calibration.  Note that this is not the factory recommended method for calibration.  I picked up this set of feeler gauges to do this.  I use the .2 mm gauge.  It’s a quick and simple process.  I start one of the demo prints and wait for the printer to warm up and print the purge line on the right hand side of the bed.  As the print head moves toward the middle of the bed to start the demo item, I unplug the printer.  The printer head and bed are hot so be careful and cautious if you decide to do this.  I move the head above each of the adjustment screws and adjust until the .2 mm gap tool just starts to drag on the head.  Complete 3 times at each point and then go back around to double check and fine tune.  This process takes just a few minutes.  Again… this is not the factory recommended solution.  If you do it, do so at your own risk and be careful – the print head and bed are hot.  Also… I did not develop this technique.  I found it on a forum.  It seems to be pretty widely mentioned.  I think the factory solution could also produce good results.  I just didn’t put a lot of time into getting good at it.

3D Printed Pub Style Tap Handle

75per_img_7266

I recently got an XYZprinting Da Vinci 3D Printer.  I think 3D Printing has a bunch of possible applications for homebrewing.  From tap handles to stir plates and on and on.

Here’s a look at a 3D printed Pub Style Tap Handle designed by “InfiniTTTy” and available on thingiverse.  A link to the STL files and project description can be found below.

3D Printed Tap HandleI printed this on my XYZprinting Da Vinci 1.0 3D Printer.  Here’s a look toward the beginning of the process.

3D Printed Tap HandleMaybe halfway through

3D Printed Tap HandleTa Da… Printed Thing!  I printed this on the Da Vinci’s Best Setting.  It took about 3 hours.

3D Printed Tap HandleThis also gets a decorative cap on the top.  You can, of course, print either of these pieces in your choice of colors.  The color is based on what color filament you’re using.

3D Printed Tap HandleFinished product.   The bottoms on these end up with a little extra material that needs trimmed.  I’ve been doing that with a utility knife.  The one thing I would change for this build would be… get a sharper utility knife.  Mine was too dull.  I could have ended up with cleaner lines with a sharper knife.  It’s amazing to me that I printed this.

3D Printed Tap HandleI attached the top piece on with Gorilla‘s Gorilla Super Glue.  Gorilla makes some stellar products including Gorilla Duct Tape.  I don’t consider it patched when using that.. I consider it permanently fixed… :)

75per_img_7266For size comparison.  From left to right Dry Erase Board Tap Handle, 3d Printed Pub Style Handle, Standard Black Faucet Handle

3D Printed Tap Handle WeightUpdate:  Google+ Friend Ray asked about material cost.  Great question.  I pulled out my AWS-100 Digital Gram Scale – Review – and weighed it up.  It came out to 26.34 grams.  At the current cost for filament (as of 1-15-15) this figures out to about $1.23 in filament.

75per_img_7300Installed.  Just served a RiteBrew Oatmeal Stout

75per_img_7286

This is a nice little tap handle.  I did some pulling and bending on it and it held together just fine.  One of the commenters on the thingiverse page indicates that they have been using it for two years.  Other styles of tap handles are available on thingiverse.  Of course, if you don’t find what you like you can always… make it.
