Category Pumps & Pressure

A rain barrel need not sit under a downspout if a sealed, sloped diverter reaches it. Preserve inflow, bypass, overflow, support, and maintenance access.

Irrigation needs a pump when source pressure and flow cannot serve zones. Measure demand, elevation, friction, and supply before sizing from a pump curve.

Rainwater tanks need pumps when gravity cannot provide required flow or pressure. Tank height, outlets, irrigation, household use, and elevation decide.

A minor accessible tank leak may accept a rated wet-surface repair, but pressure, material, location, and water use limit options. Lower the level whenever possible.

Choose a camlock by mating type, size, thread or hose end, material, gasket, pressure, temperature, and liquid compatibility. Confirm both halves first.

One inch of rain on one square foot equals about 0.623 U.S. gallons. Multiply by horizontal catchment area and collection efficiency to estimate usable yield.

Solar-pump life varies across pump, motor, controller, panels, and batteries. Correct sizing, water quality, cooling, dry-run protection, and upkeep help.

Diaphragm-pump life depends on duty cycle, pressure, fluid, temperature, dry running, installation, and maintenance. Falling flow, leaks, or cycling can signal wear.

Prime an irrigation pump with power off by filling housing and suction line, sealing the port, opening needed valves, and checking for suction leaks.

Panel count for a 1 HP pump depends on motor input, startup surge, controller, sun hours, voltage, and batteries. Size from measured electrical demand.
