Super high quality and easy to install. My setup runs water through a water meter then the lack tank flush kit, then my 50-55 psi reducer and through a previously installed whole house sized water filter. This way the flush process has full shore pressure to maximize the flushing power. Pressure during this process is irrelevant since it is open ended. The meter lets me know how much water I use during the flush and also how much water I preload the black tank before treatment. Worth the expense an effort! Love it!
