Answers to Common Questions
View All FAQsWhy Is My Water Heater Not Heating Up Despite Resetting the Button?
If the reset button didn’t restore hot water, your water heater likely has a deeper issue that needs a professional diagnostic. Flatley’s Plumbing Express performs full on-site diagnostics, then completes same-day repairs when possible. If repair isn’t viable, we can replace the unit on the spot because our trucks are stocked with water heaters. We service both tankless and natural-gas models and can handle gas line work and any needed municipal permitting. Exact pricing depends on inspection; your technician will confirm costs on site.

If water is leaking from the bottom of your water heater, shut it down and schedule service. We offer same-day diagnostics and, if repair isn’t feasible, on‑site replacement (tankless or natural gas models).
Quick steps:
- Turn the cold-water shutoff valve clockwise.
- For gas, set the gas control to Off; for electric, switch off the breaker.
- Contain the water and avoid using hot water until inspected.
We serve Lake Forest and nearby suburbs.

For most homes, a DIY water heater install is not recommended. Installations can involve gas lines and venting, and permits may be required. Our technicians perform a full diagnostic, explain findings, and can repair or replace the unit the same day. We install tankless and natural gas water heaters, and our vans carry water heaters for on-site replacement. We also handle related gas line work and help with municipal permits when needed. Serving Lake Forest and nearby Chicago suburbs since 1960.
