Never run out of water. Endless hot showers. Once you run out of onboard water, turn your 3 way valve to OUT and draw water from an outside water reserve container with your onboard pump. This kit allows you to draw water from your onboard water tank or an outside reserve water tank. This kit includes: waterproof switch, electrical wires and connectors, high pressure hose, 3 way valve with cover plate and screws, new food grade lines from your onboard water tank to 3 way valve, 10’ flexible hose with spray nozzle, and a new 12 volt high pressure pump, outside quick connect and mounting bracket, quick connect hose with filter, inside tank hose with filter. This kit does not include: GoWesty City water box. This kit runs completely separate from your sink faucet system. The stock city water system will be eliminated and used for your outside rinse. A new water draw line will be installed into your water tank for the rinse kit. This will allow you to draw water from your inside water tank.
