Replaced Thetford recirculating with RV flush type

My wife hasn't been happy with the recirculating toilet in our 2619 so I replaced it with the RV flush type. I picked up water at the rear drains ran plastic rv water pipe from the cold water drain under the floor and up to the back of the toilet. I have tested it with water only draining onto my lawn.
We camp only where we can have full hookups, so I don't think there is going to be a problem, if anything we may have to flush a couple of times? Test run will be this weekend. I'll post the results so if anyone else has thought about this will know if it works or not. I figured I'd try it and if it doesn't work I'll just put the Thetford back. I bought the new RV flush type from PPL in Houston for 119 bucks. It bolted right on with no modifications at all, the whole project took about an hour!
