How hard and expencive would it be to build your own water recycling system? anyone done it before?
I would base the design or purchase on how many machines you are going to run plus oversized for the possibility of adding another machine on some jobs and the gun not always on the full time that you are there on the job.
There will be some loss due to evaporation and absorbtion, not sure if there is a formula or average but I would guess the further south you live the larger the % of loss of water you will have.
Like if you have 2 of the 8gpm machines, I would want a system that could handle at least 24gpm so if you added another machine temporarily on some jobs it would probably handle it without having to stop the job or slow down too much
Design is rule #1 keep it basic, simple ,and efective. Less moving parts means less parts to break down on the job/road. I have a few blueprints on how i will build mine for what i am going to use it for. and as Chris said having the extra power just in case is always good. youll have room to grow or use it for those strange jobs that we get from time to time. the beauty of fabing your own system is you can custom fit it on your rig and put other goodies on it.
I will be putting together a few trailer units shortly
