Grey Water Transfer System
Hi. We have a 2015 V3605. We ran into the problem of the Main grey tank filling up too fast. The kitchen sink, the shower and bath sink are all plumbed to this tank. With little to no use on grey #2. So below is description and pictures of solution.
First there is NO cross-connect between this system and fresh water. The blue line is the suction side of main grey tank. This is input to its own pump. The pump outputs to 3 solenoid manifold. The solenoids then can be individually selected to transfer the grey water; Grey #2, Black 1, or Black 2. The red switch is for pump, the blues are for discharge solenoid.
These are 12vdc devices. Pex and ABS on plumbing side. The suction line is braided poly 3/8" with brass barb (to keep it on bottom of tank). This was "fished" down the ABS cap before final gluing.
Usage prior to this was main grey filled up, other tanks at 1/3 or less. 4 day weekend having to go dump one tank with all that empty space in other tanks was annoying to say the least.
