Buying Guide

Match accessory to system type

Choose items rated for your application—marine/RV components for bilge or onboard tanks, sump-specific float switches for basements, and pressure-tank tees for well systems

Check cord length and installation orientation

Float switches with longer cords (10–20 ft) or adjustable cables offer flexible placement; note whether the float is vertical or adjustable to suit your basin

Verify pressure and tank specifications

Accumulator tanks and pressure tees should list PSI or compatible switch ranges (e.g., 43–60 PSI) so they match your pump’s cut-in/cut-out settings

Prioritize durability and ingress protection

Look for waterproof or IP-rated components and corrosion-resistant materials for marine, outdoor, or damp environments to reduce failure risk

Consider safety and backup features

For sump systems, options with alarm compatibility or separate backup float cords add redundancy against overflow or pump failure
