I agree with SurfaceMedic, I went from 5.5 to 7 and didn’t gain anything but headaches with the 7 GPM. IDK why but it is just a PITA to use relative to the 5.5. I run 1/2" hose and 3/4" pickup line so it is not a restriction issue, unless you include the Banjo quick connects because they do neck the ID down a lot.

I have a 5 gpm as a backup to my backup but have only used it to transfer SH from drum to tank. I’ll have to give it a try next season. There are times where I wouldn’t mind a little less flow.
I’ve experienced that before. I run a 7gpm and I’m going to pick up a 5.5 for next season and a new 7. I want to go ahead and have both mounted and ready to go where all I have to do is swap the hoses over and go to work.

I run two 5.5 gpm northern tool pumps. Not at the same time obviously. I have no trouble out of either of them plus if the break take it back they will replace it. 1/2 kuri hose.
I think I plan on using some 3 way valves that I can turn depending on which pump I want to put to work.

Does Midwest have a newfangled mixing valve system? Ours go before the pumps

@garry.cooper No, I typed that wrong. Just meant it won’t really matter what pump you use with a mixing system. But you are right sir, it is before the pump.
Now that’s an idea. I guess my only concern with that is SH or whatever sitting against the valve or in the line of the one not in use. You’d have to be sure to flush each time or you may forget and have it sitting there until the next use.

Just gotta flush every thing at the end of the day anyways right ? just have a few more lines to tend to is all.
I’m gonna work on getting 4 different chem lines to each machine this winter, just gotta simplify it for the help.
Very true. Rinsing really does prolong the life of most things in this business. Gotta take care of what makes you money.

Hey thanks for providing that info for me. I was scrambling to find parts and someone who knew what they were talking about during lunch. Had I saw this prior I would have called your man!
I read that the accumulator can reduce flow if needed is that true?
No worries, just trying to help and get you in touch with someone that could get you taken care of with what you need.

Much appreciated!
No clue. Never used one. Haven’t had any issues with my uber basic setup
The only reason to use an accumulator is to cut down the cycling of the pump. This occurs mainly if you’re walking roofs and don’t need much flow and have small restricted flow nozzle. If you’re usually shooting from the gutter or washing something then it’s no big deal and probably not necessary.
Good to know thank you. Cody from powerwash.com explained to me that using the 7gpm at 100psi I should be able to just shoot from the gutter and reach most peaks on regular size homes. It was only $82 for the accumulator so I went ahead and ordered it, If for at least just saving the life of the pump. I am stoked on the 12v. Now we can apply chem and rinse with the PW behind. Want a proportioner next!
Hey Brad, I just messaged @Seandz, thanks for the referral, not sure why I didn’t get a notification…

We rarely use them. It’s hard on a pump to cycle on and off and an accumulator only reduces the cycling. It’s one more component to leak and break. Many times the bladder will rupture and the user doesn’t even know it. But some people like to use them and do just fine with them. If you’re wanting to run a smaller nozzle and reduce the flow, an accumulator will help. If you’re regularly reducing the flow, consider a lower gpm pump for your next pump and eliminate the accumulator.
