I DID THE UNTHINKABLE FOR A BM20 BOTTOM TAP

Unread postby rmklaw » Mon Mar 19, 2018 11:03 pm

Well. Finally built-up the guts and drilled a whole on the bottom of my BM20 to install a new tap. I used an SS Brewtech bulkhead fitting, a valve, two elbows and a male extension fitting.

You are braver than me!

I'm still building up the courage to drill a hole in the lid (which can be replaced for €20) for a CIP ball!

Nice looking mod.

Is that a nut on the inside of the kettle now? How tall is it?

The nut is about 5mm, hence the amount of liquid left is very minor and dealt with a slight tilt to the right. The drilling was very easy with a special bit since the bottom if fairly thin and not double clad. The fitting is sold specially for that purpose by SS Brewtech.

Now look what you have started. :D

I think the clue is in the tile "unthinkable" - tee off the pump is much better (and safer) ... LOL

**** Update ****
The kettle had to be replaced.

Yes. I did. I needed to replace the kettle because the bottom of my old one was not 100% flat after welding a fitting and the malt pipe would not seal completely. So I decided to replace it with the Plus. I love Braumeister quality and support.

As far as how effective the cooling is, I am going to run a test today and report back.


Read this. viewtopic.php?f=4&t=2849. Before proceeding.

I have updated this post for any future readers which may consider it is a good idea, with understanding the risk.

Probably, but I had problems finding BSP fittings to modify the pump fittings. Now, I am now considering installing another bulkead fitting with the whirlpool nipple from SS Brewtech. :mrgreen:

Another interesting mod!

I'm not sure how useful it will be though, whirlpool is good for -
- dropping trub to the centre of the vessel so it doesn't reach the fermentor
- improving cooling time if an immersion chiller is used

but if you are using a external trub filter and plate chiller neither of these are really needed.

doesn't stop it being a cool mod though

I am considering the whirlpool to protect as much as possible the Therminator plate chiller from trub, etc. More of an abundance of caution. As far as the tap mod, works great. tested it yesterday and it empties the vessel leaving about 5 milimiter at the bottom which drains completely with a small tilt to the side. :beer:

I also have a hole in my BM50. It is welded. That's handy: you can install a CIP ball for cleaning.

I did think about a CIP ball on one of gandalfs' pump risers. Are they any good?

That is a great idea. I have to see if a CIP threads into the bulkhead fitting.

You could adjust the height of the riser to the spray - I am just not sure the pump is man enough.
