I dont see why you would need anymore than a single delvan? There is so much waste with run off I dont see the need? Unless you were using 1 pump for roof cleaning and the other for something else.
1) One guy could clean the roof while the other cleans the house, using two pumps.
2) always have a bak up for when the first pump fails, and they always fail, takes about 5 seconds to switch pumps and your up and running again. Then you call Paul and say send me another pump and for about $125.00 another pump is on the way.
3) Let' say you have a job and you need to use a totaaly safe cleaning product like I am using for a certain client. I cant let my cleaning product mix w bleach or any other type of cleaning product. I just use the other pump. I have a total separate tank, hoses, gun for it. It works out great for me. One pump that I use that has chemicals run through it, the other is my safe pump, that has no chemicals that runs through it.
Many many different things you can do and adapt with the two pump system.
