blake jernigan 14 Report post Posted January 11, 2010 Just came across some good reading on the Delavan Pumps. But I do have one question, what is everyone running the Bypass or the Demand type? PowerFlo Fat Boy Diaphragm Pump Share this post Link to post Share on other sites

All Surface 24 Report post Posted January 12, 2010 I use 12volt and an air pump delivery system. Neither has a bypass. Both are demand. I did however use a Comet pump for sometime with a bypass and had a lot of problems with it. Share this post Link to post Share on other sites

All Surface 24 Report post Posted February 17, 2010 How long do the batteries last that run these? how often do you recharge them? I couldn't tell you! LOL...Actually I have mine set up to where it is always being re-charged whenever my truck is running. I have it wired through my trailer and then to a seperate plug which runs under my truck and to the truck battery. I've heard some guys say that they can do three or four Roof Cleaning jobs before theirs dies out and others less. I think it would all depend on the size of the Roof you are Cleaning and how long it takes you. Lots of different senarios. Share this post Link to post Share on other sites
Russ Spence 76 Report post Posted February 17, 2010 I have my Fatboy set up with dual 750cca deep cycle marine batteries, I can clean 5 roofs easily w/o recharging and still have some power left but not enough time in the day. The suck the current though so I recomend 2 batteries Share this post Link to post Share on other sites
CCPC 26 Report post Posted February 21, 2010 A good rule of thumb if you don't have it wired to automatically charge is to charge everyday after using it. Last thing you need is to cut it close and run out of charge in the middle of a job. That would blow. Share this post Link to post Share on other sites
Chris Tharpe 40 Report post Posted February 21, 2010 If the battery is on your PW trailer and you just to happen to have another battery on that machine, just run the two in a series and you won't have to worry about charging it every. If she gets low just fire up the machine and bypass the water long enough to charge up the batteries. this may not be the best avice however it works and its something we do with our's Share this post Link to post Share on other sites
Chesapeake 14 Report post Posted February 22, 2010 I run demand pumps. On my trailer setup I had a 5800 wired into the battery on the skid. That way it was usually recharged everyday that it was used. On my flatbed I run the Fatboy, and have it wired into the 2 truck batteries. Its charging on the way to the job and charging on the way home. Share this post Link to post Share on other sites
