Category Pumps & Pressure

A 3/4 HP pump has no fixed GPM; flow depends on design and total head. Read its curve at your elevation, pressure, pipe friction, and suction conditions.

Diaphragm pumps can be reliable for intermittent, self-priming service when sized well. Duty, pressure, fluid, heat, dry running, and parts matter.

An elevated rain barrel produces about 0.43 PSI per foot of water head, enough for some low-flow uses but not sprinklers. Height and friction set pressure.

Rainwater-tank pump cost varies by type, flow, head, controls, materials, installation, and accessories. Compare system cost, energy, service, and warranty.

Attach a pump through a screened barrel outlet or submersible intake using supported hoses and compatible fittings. Prevent dry running and route power safely.

Empty a tank without a pump through its low drain, gravity hose, or siphon when the outlet is lower. Control air, hose routing, stability, and discharge.

Decide which pump fits by defining water source, required flow, total head, solids, suction, power, duty, controls, portability, noise, and maintenance support.

Connect a pump to a rainwater tank with a screened intake, isolation valve, unions, supported pipe, and suitable check valve. Prevent dry running.

Choose a booster from inlet and target pressure, peak flow, total head, pipe size, controls, noise, power, protection, and the manufacturer's curve.

Build a solar pumping system by matching pump flow and head to panels, controller, wiring, storage, and batteries. Add safe mounting and dry-run control.
