As great as my electric water urn Hot Liquor Tank (HLT) has been, it has always had a slightly leaky tap. This was never a really massive issue but, seeing as the tap was quite slow to drain water, I did see it as an opportunity to drive some further performance gains from the tank.
I’ve now installed a 1/2″ ball valve in place of the old tap (see comparison photos below). It provides the following benefits:
- No longer have to hold the tap down the entire time – just set and forget
- Can set the flow rate easily
- Much higher max flow rate – I estimate triple what I had before, meaning less temperature loss waiting for the mashtun to fill
- No leaks
- The ability to attach things to the end of it – like a sparging device
I also took the time to calibrate the sight glass. Now it sports 3L increments all the way up to the 18L mark.
