Tap on Water Urn - Replacement

[woolley2002]

Hi,

Has anyone changed the tap on a standard water urn to one of the taps shown in the picture?

If you have how easy was it, and what did you use to form a good seal so there was no leaks.

Thinking this would make sparge process easier as you can fit tube to the tap.

They are handy enough and some may need a bit of filing though would go with silicone washers inside and out and a washer at the back to stop the nut disforming the seal and minimise contact of the brass nut as it will react with the stainless in the urn.

My urn is approximately 1/4 inch tap hole. Actually I think it’s metric measure. Anyway rather than drill it out to take 1/2 inch tap as double walled urn what I did was just de-burr / drill out the hole in existing tap to 10mm and jammed the grainfather wortometer with some silicone hose in there. Someone else on the forum used 10mm copper. I do need to conduct more leak tests. I did consider a 1/4 inch to 1/2 inch reducer.

Out of curiosity, what is the purpose of the pump. Do you use the urn as an all-in-one device?

Recirculation and after boil (edit chilling) transfer wort to fermenter. Sort of following inspiration from on the forum and YouTube member Tube dinoz. It’s got a couple of glitches I need to iron out.

Before I used a submersible USB pump rates to 100°(Myass) and used that for recirculating my mash to the boiler to maintain temps and worked a treat until the pump packed up then I got serious with the conversion and made a heat exchanger and it's still going.

Yeah I was thinking about a heat exchanger. Well using the copper chiller dual purpose. I like the idea of using it to control mash temps and cool. I haven’t totally thought it through though.

20l tea urn with 10mm microbore copper tube that recirculates the mash keeping a stable temperature.

It looks like a similar boiler. What pump do you use?

Brushless 12v and great to use but you must open the valve to prime as they don't like to get run dry and a 12v 5watt supply needed.I had plenty 1 and 2 watt supplies about but no good but a worthwhile investment.Pump and supply works out just under £23 when I got them.

 

[Gerryjo]

That's a 12v 5w pump around £23 all in.

Sorry so are you pumping the mash about through the pipe or pumping clear water through pipe as heat exchanger into another vessel? Hopefully that makes sense

Whilst mashing I pump the wort through the copper coil in the 20l urn filled with water and set to 68° which allows for temp drop maintaining at 66°.
