Frequently Asked Questions

Start by identifying the heater’s make and model number, then refer to the parts list for that model. Match key attributes like fittings size (e.g., 1½″ or 2″ unions), electrical terminal type, sensor mounting style, and pressure switch specs. If you’re replacing a union or gasket, measure the pipe size and check the original hardware for reference. Correct fitment ensures the replacement hardware keeps your heater safe and efficient.

Yes - replacing worn or corroded hardware parts (such as unions, gaskets or hi-limit sensors) can restore proper flow, sealing, and safety control in your heater. Maintaining clean, tight fittings reduces leaks, prevents flow disruption, and avoids overheating. While hardware replacement isn’t a complete system upgrade, it often restores reliable performance at a lower cost than full heater replacement.

You may choose to replace individual hardware parts when your heater is still structurally sound and lacks extensive corrosion or major mechanical failure. If you notice signs such as leaking unions, failed sensors, recurring pressure switch trips, or brittle gaskets — but the heat exchanger and burner are still functioning — then replacing hardware is a cost-effective maintenance route. If the heater is old and has many failing components, then full replacement may make more sense.

Some hardware parts are cross-compatible (e.g., unions with standard dimensions), but many are brand-specific (sensor housings, pressure switches, mounting brackets). Always check the part number and specifications. Using mismatched hardware can lead to improper sealing, incorrect sensor readings, or voiding of warranties.

 Regularly inspect heater hardware for:

  • Leaks at unions and gaskets — tighten or replace if visible.
  • Corrosion or scale buildup on metal fittings and sensors.
  • Loose screws, oxidized terminals, or wiring discoloration on hardware.
  • Flow or pressure switch resets that might indicate failing components.

Timely replacement of worn hardware ensures the heater continues operating safely and efficiently.
