You are just doing things quicker than I did. There were only 2 of us in the area using wfp when we started, and our knowledge was limited. We didn't have forums back then and basically knew nothing. Everything we learnt was by trail and error.Looks great that thanks for the photo. I was thinking of building a shed at the back of the garden but by the time I get a hose from there to the front where the van is it's probably over 100meters (may of stole some council land when we got a new fence lol). So my next option is to make a little one on the back of the house which luckily on the kitchen wall is some plug sockets. So can make an outside plug beforehand and get it all done and try not make it look ugly ?.
Will save me a lot of money with the big school i just got, the spotless water really eats away at the profit quite a lot.
Who'd of thought there's so many things to learn with window cleaning!
I initially had a 225 gpd r/o which I used to fill my tanks on a trailer (3 x 150 litre tanks linked together.)
I processed this water overnight. The r/o was outside at the back tap and run all night in temperatures below freezing. The r/o never froze, as 'warm' water circulated through it all night. When the trailer tanks were full in the morning, I uncoupled the r/o and put it inside in the bath to keep it at inside room temperature. If any water leaked out of the r/o, it went own the drain.
It was about three years later that I processed water into an IBC tank in the garage using that same r/o upgraded to 450gpd by changing the membranes to 150gpd ones.
I winter, I had the r/o mounted on the wall in the garage with a towel over it as a tent with my mechanics lead light underneath with a 100w bulb in it. I used that lead light for the next 3 or 4 winters before I built that cabinet and assembled a 4040 inside it. That photo was taken about 11 years ago. Since then, I have added a water meter, so I know when to change my prefilters.
So all in all, we started as traditional window cleaners 20 years ago, converted to wfp after 3 years, and it then took another 6 years of slow progression before reaching the point of when those photos were taken.
ps. I purchased that lead light with 4 axle stands when I was 17 years old in Zimbabwe. They are still used today, some 54 years later. My lead light has been through a lot of bulbs though.
