I did a little experiment at then end of last year
To see how high it could let my water go to
Without compromising quality.
I had loads of in and out jobs booked in so I thought
It would be the perfect time to do it with the sun
Being low in December and November
Got to 037 with perfect results

I was very surprised!
I would like to add I'm using 000 again now as the price
Of getting the water to 000 is not worth using anything but..
