I was thinking of upgrading my cold water 18 honda, 5.6 gen to a 24 honda, 8 gpm cat. I need the water volume to speed up my cleaning. Any suggestions on engine type or pump type. I understand the water requirements etc. Thanks, Jim
 
Do you have the water supply to support 8 GPM?

A 525 gallon tank will give you ~475 gallons of useful capacity or less than 60 minutes of cleaning time. If you have a 6 GPM fill into a 100 gallon surge tank then you may be able to get 45 minutes of cleaning time. But 6 GPM is on the high side for both rural and urban supply, on average. Even doing the 6 GPM fill into the 525 gallon tank then you can expect about 4 hours of work.

That said your cleaning time will be reduced so you may not need to worry about the time available. However, if you are in a jurisdiction that requires you to recover water then your problems compund.

On the surface, 8 GPM seems like a good idea. In looking at the total costs you need much more expensive guns and hoses, pumps and parts are more expensive and maintenance is in greater demand. For most applications and places, 6 GPM is a functional upper limit with 5-5.5 GPM being most usable in most areas.

Not wanting to discourage you, it is vitally important that you look at ALL of the costs associated with any change you make. Businesses grow and profit by knowing all of the costs and containing what they can to maximize return on the dollar. Ask as many questions of your plan that your plan seems to answer. I most likely forgot to ask some above but I hope you get the idea?

Hope this helps? Cheers.
