It's been a while since I bought my pump. Good decision going 12 volt. You musta read some.

the 7800 series is what I think I got. Thats just 2gpm. To me its fast enough.

The 5850 is what most guys get to or start with. Thats the Fatboy, I think.

 Hi Gutterdog,
I went from the 2 gpm Delavan to the 5 gpm and recently went back to the 2 gpm.
I felt there was too much runoff from the 5 gpm. I still have both with me all the time, but I use the 2 unless I really need 5 gpm.
Like you said, it's fast enough, plus I don't have to drag a 3/4" garden hose around. A 1/2" ID hose works fine for 2 GPM.
There's a time and place for both and probably even for a Fat Boy, but for most jobs i'm back to 2 gpm. I wouldn't mind if Delavan were to make a 3 gpm with 60-100 psi though. Be a nice half way point for me.

You are right, Chuck.  It has been my experience that many guys that stepped up tp the Fatboy, are now going back down to the 5850 or sometimes a 7812.

The fiberglass in the polypropylene manifolds of the non-kynar or non-pvdf air diaphragm pumps, J*** B***'s, U***'s, C***t and H****'s will be eaten up by the hypochlorous acid as the chlorine runs through them.  The fiberglass acts to increase the integrity of the manifold but is the weakest component when faced with the chlorine.

They last much longer with lots of rinsing and maybe even a neutralizer such as sodium thiosulfate.  (Sodium thiosulfate is a bit pricey!)

I have the 5880 and a Fatbot........most of the time I use the 5880..........I may be interested in the 7812 for some homes I will have to look into it.
