TPP+Watersecure Hybrid System Using Gravity Tank
On properties that have usable elevation change, water can be stored in a tank at a high point of the property, naturally pressurized from gravity (A). A tank must be located 95 feet above the house for gravity to provide 45 psi worth of water pressure. The calculation can be done for any type of elevation using the equation 1 psi = 2.13 feet of head. If your property does not have a steep enough grade, a booster pump takes the incoming psi and BOOSTS the water up to acceptable household levels.
In this example, let’s say that the tank is 30 feet above the house, meaning gravity flow is producing 14 psi at the house. A Tankless Pressure Pump (C) identifies the incoming psi and boosts water pressure up to 45 psi, good enough for showers, flushing toilets etc. This Tankless Pressure Pump runs off the battery bank of a Watersecure (B), a solar generator that can power both the pump and other appliances inside the house. Tankless Pressure Pumps only run on 24V battery banks, which fits with our smallest Watersecure 3k system.
