Cornelius KEG Washer

This tool can be used to clean your KEGs or fermenters with just a tiny effort. It can save quite a lot of time.

While commercial solutions exist, this design is fine replacement which will cost you a lot less. The total price - depending on the pump you use - will be well below $40.

I only suggest feeding this with cold liquids (no more than 30°C) to avoid damage to the pump. You can use sanitizer such as Chemipro OXI, a PBW, or just pure water to rinse stuff up.

This is based on this design which I almost fully reworked: use only the KegStand.stl part . The only things borrowed are the general idea and Keg stand. The rest of the parts was designed from ground up.

You will need following parts to make this work:

• A submersible pump. I used this but a different one can be used easily. The only thing you'll need is to design your own attachment part. The thread on the manifold is ISO Standard M16 with 1.5 pitch. I suggest using something rather powerful (2500L/h+, ~60W).
• M16 electrical installation pipe. You'll need around 2M length. These pipes should be easily obtainable at your local hobby shop. You'll have to split it to create 4 legs (~30 cm) and a shower pipe (~45 cm). The actual length will depend on specific parts used.
• A bucket that will fit the pump and the KEG stand. Again, this should be easily obtainable at your local hobby shop. I used a 20L bucket for construction sites.
• 2x ball lock connectors & sufficient length of beer line to connect your KEG.
• (Optional) For best results, ball lock fitting insulation can be attached on the 3D-printed part. But it works without it just fine.

You'll also need to print following parts:

• 1x three-way manifold
• 2x ball lock fittings
• 1x shower
• 1x pump attachment
• 1x KEG stand

I designed this in OnShape. The design is publicly available here in case you need to make some adjustments:
