Can someone tell me the difference between the FB 2 with bypass w/continuous operation and the FB 2 demand switch which operates only when flow is required, and which is better.

Thanks

Gene you may be better off starting out with a 5850. You are just starting out and less flow may be better for you.

5850 is plenty of pump, super reliable.

It is cheaper Art but which one would last longer? the continuous flow or the on demand pump?

Diamond Roof Cleaning · Approved Exterior Cleaner

You need a on demand pump. They will both last the same amount of time 5850 or the fatboy.

We have used the 5850 pretty much exclusively and they do last as long as you follow Bob's recommended installation procedure. The fatboys(on demand) are good pumps as well. If you go this route make sure you get an accumulator tank.

PS...when I say the pumps last I'm talking about a season(+-) depending on the work load. They are cheap enough and it's the cost of doing business. Always have a back up too.

Like Hank said, whichever one you choose - 5850 or Fat Boy, buy two!!! Make sure it's on demand.

I like em both but when I have huge amounts of open field I need my fat boy. I prefer the 5850 for typical houses though. Definitely better for someone starting out.

I agree that the Delavan 5850 is perfect for all around general Soft Wash use and they last if you treat them right. Flush them out with fresh water at the end of the day. Here is a video of a pump we had for over a year and still kicked azzz! Look at the verticle distance. If your looking for anything more, you may want to look into a booster pump.

As a side note: I use two deep cycle batteries, connected in parallel. Doing this, maintains a longer charge and puts less stress on the pump. Towards the end of the day a single battery loses its charge and that puts a lot of stress on a pump.
