Before buying a faucet
Check the number and spacing of mounting holes, sink clearance, supply connections, and accessibility beneath the sink. A replacement should fit the fixture and the plumbing, not just the photo on the box. Ask about installation before ordering an unfamiliar model.
Before replacing a toilet
Confirm the rough-in dimension, available space, and condition of the flange and supply valve. Discuss height and bowl shape for the people using it. A new toilet does not fix a damaged downstream drain.
Before selecting a disposal
Check cabinet space, mounting compatibility, the drain arrangement, and electrical requirements. Have a leaking or malfunctioning unit assessed before deciding whether replacement is needed. See disposal service.
Before choosing a water heater
Tank size or a headline tankless capacity is only one factor. Fuel type, hot-water demand, installation space, venting, electrical capacity, and local requirements shape the choice. Discuss a complete installed scope with the water heater service team.
Evaluate documentation and support
- Read the manufacturer’s installation and care instructions.
- Confirm what the warranty covers and who handles a claim.
- Check replacement-part availability.
- Clarify responsibility for a customer-supplied item and missing parts.
