What Is the Difference Between a Boss Fitting and a Bulkhead Fitting?
Boss fittings are molded or attached to tank walls, while bulkheads clamp through cut holes. Compare installation, replacement, sealing, threads, and support.
Roof collection, tank plumbing, fittings, monitoring, and controls.
Boss fittings are molded or attached to tank walls, while bulkheads clamp through cut holes. Compare installation, replacement, sealing, threads, and support.
Bulkhead replacement cost depends on fitting size and material, tank access, connected plumbing, wall damage, and labor. Compare the full repair scope.
A bulkhead fitting is also called a tank fitting, tank connector, or through-wall fitting. Match the actual thread, size, material, gasket, and installation.
Type C camlocks have a female coupler and hose shank; Type D has a female coupler and female pipe thread. Compare mating parts, size, gasket, and thread standard.
Type 1 and Type 2 are not universal ball-valve categories; meaning depends on the maker or standard. Check body, ports, materials, connections, and documents.
House water pressure often works well around 45–60 psi, while plumbing limits and local rules govern. Measure static and flowing pressure before adjusting it.
Polypropylene with an EPDM gasket works for many rainwater tank connectors. Compare UV resistance, water compatibility, strength, threads, and pipe loads.
Tank overflows are often around 3–4 inches, but correct size depends on roof area, storm intensity, inlet flow, screens, fittings, and local requirements.
Ball-valve lifespan varies with material, water chemistry, pressure, cycling, debris, installation, and weather. Learn what causes wear and when to replace it.
Rain-barrel spigot hole size is set by the bulkhead, grommet, or adapter body, not faucet size. Use the fitting template and test on scrap if possible.
