Category Tank Fittings & Plumbing

Bulkhead fittings form watertight tank penetrations when the hole, gasket, surface, tightening, and connected pipe are correct. Learn why joints still leak.

Size a rainwater tank from roof catchment, rainfall, demand, dry periods, space, overflow, and budget. Compare yield and use rather than capacity alone.

Rain-gauge accuracy depends on a level, clear opening and calibration more than overall size. Learn why standard openings and proper placement improve readings.

A 2 HP pump's lift depends on its curve, design, flow, pipe friction, elevation, and suction. Use total dynamic head rather than horsepower alone.

Make a DIY rain-barrel spigot with a hose bib or valve, correctly sized hole, bulkhead or sealed fitting, and support. Position it above sediment and test for leaks.

Drip line often works on the soil under mulch; subsurface depth depends on plants, soil, emitters, cultivation, and pests. Learn how placement affects watering.

Install a bulkhead fitting through a correctly sized, clean hole with its gasket against the proper surface. Tighten evenly, support the pipe, and test for leaks.

Raise a rain barrel enough to fit a container below the spigot and improve gravity flow, often 12–24 inches. Size the stable base for the barrel's full weight.

Water-tank layer count can affect light blocking and insulation, but material quality, UV resistance, construction, certification, and intended use matter more.

The rain needed to fill a 55-gallon barrel depends on connected roof area and collection losses. Use 0.623 gallons per square foot per inch to estimate fill depth.
