Here is what I got, for anyone interested
The cement is going to be poured on Monday, so you can see the unit clearly as it would sit under the floor.
It is hitched up to a water system so that I can flush the gutter out at anytime by turning on the water valve. The gutter drains into a sump which has a wax screen to catch all the wax before it enters the septic system which is plumbed in with the appropriate check valves. Its a SS unit so corrosion is not an issue. The price of this system is basically no more than if I had priced the guys to form in a cement gutter system
