T500 water needle valve

[Peteren1]

The water needle valve that comes with the T500 is very narrow in its adjustment.
A very small adjustment of the valve causes a large movement in the water temperature.
Is there a fix for this?
Cheers

You could swap it out for a normal needle valve but you will need to “adapt” it , there is no over the counter fix
Maybe that’s something I should be looking at :laughing-rolling:

Adapting it is easily done, adapting it to work is another thing.
What is needed here, is it less flow so small adjustments make smaller changes?
I'm poking holes in the dark here, what makes the water valve less sensitive in its operation?

You need to reduce the flow rate ie make the pipe smaller, the smaller flow will be affected in a lesser way by the small changes and you get a wider range of movement for less output change. Be aware the smaller pipe MUST meet your maximum demand for water. In other words, needle valve wide open the flow is sufficient to cool the condenser..

This will allow a garden hose to be connected to your kitchen sink tap:

Then 5 Star have the 1/2” needle valve:

And the 1/2” male to hose tail:

I just can’t get from 13mm garden hose to the 8mm inlet of the T500

This is what I did with my T500 water management.

The ball valve is to reduce the mains pressure coming into the needle valve. This reduces the effects of
mains fluctuations when someone turns on a tap or flushes the toilet.

There are adapters either side of the ball valve, one to take a standard hose fitting, the other to join the
ball valve to the needle valve.

The ring with the bolt (home made) in the needle valve spindle greatly increases the sensitivity of adjustments,
a move on the end of the bolt translates to a much smaller movement at the spindle, making for finer adjustments :handgestures-thumbupleft:

All parts, except for the needle valve, from Bunnings.

Cheers guy's, I will put together the ball valve idea and see how it works out

I have heard alot of people just put a peg on the needle valve handle. anything that gives you a more precise control would work.
I have always recirculated my water so my pressure were alot less and never really had an issue with it.
