I've had 6 different DRV's and NEVER had a check valve leak in more than 20 yrs. Just makes sense to keep in place. Your set up still appears to have the exact # of connections, so what is saved? What would happen in the middle of flushing and you suddenly loose water pressure? It could back wash long before your timer went off.
Walt=don't remember both check valve and vacuum breaker being there, but like I said, never had a problem. Good luck with yours.
