Water Pressure solved

[vino-tinto]

I've Solved my water pressure problem by fitting a central heating header tank above my T500. The tank is fed by mains pressure regulated via a shut off valve then gravity feeds the still.



The cost was:
Tank £6.59
Lid £2.57
Shut Off Valve £3.65
Torbeck £5.98
Tank outlet £2.08
Pipe & fittings I already had, so after testing OK, feeling pleased with myself.

That's a simple but ingenious solution for any liquid management still well done

Simple, effective and clever.

Ran a wash last night using the gravity feed tank, temp varied between 50.5 and 56.5, took a long time to work out why, then I sussed it. I had not set the water level high enough in the tank, so the pressure was a bit low. After twiddling the float adjuster on the Torbeck it settled at 52.5 +/- 0.4.
For my next trick, I want to feed the water to and from the condenser separately to that of the reflux coil with a recirculating system.

Thanks for the feedback!
Question, by 50 CM above the still, do you mean the surface of the water in the tank is 50Cm above the top of the column or the cooling water inlet? I am a little cramped for space. I can put my still on the floor but then I have to pump the exit water up into the sink.

The outlet from the tank was 50cm above the level of the needle valve.
I forget where I found the formula to work out the pressure, but I would think even 25cm would have enough pressure because of the surface area of the water would far exceed the surface tension of 5/16" pipe, just like a syphon.

Hi there 1 metre equals .1 of a bar. You would require 10 metres of head to get 1 bar.
