Tankless water heaters fail at install when the gas line is undersized, the venting is wrong, or the condensate is not routed to a drain. We size by the home’s peak GPM demand, run a properly sized gas line where the existing one is too small, and install the stainless or PVC vent the manufacturer specifies. We work with Rinnai, Navien, Noritz, and Rheem.
Gas-line sizing to deliver full BTU at the unit
Sediment trap and isolation valve service kit on the supply side
Stainless or polypropylene venting per the unit listing
Condensate neutralizer install on condensing units
Outdoor or indoor mount with code-compliant clearances
Recirculation pump install where the home has a return line
Every install ends with a recorded flow rate at three fixtures and a printout of the unit’s commissioning log.
Why Professional Tankless Water Heater Installation Matters
A tankless unit is a precision burner with a tight gas-flow and vent envelope. Skip the gas-line resize and the unit cycles into error codes. Skip the condensate routing on a condensing unit and the acidic drip eats the floor. Correct install is the entire reason a tankless unit lasts 20 years instead of 10.
Sizes the gas line to deliver full BTU at peak demand
Confirms the venting meets the unit’s specific listing
Routes condensate through a neutralizer to protect the drain line
Keeps the manufacturer warranty intact
Adds isolation valves for the annual descaling service
A tankless unit installed correctly will serve the home for two decades. The same unit installed wrong rarely makes it past five years.

FAQs
What size tankless do I need?
Most three to four-bath homes need a 199,000 BTU unit, which delivers 9 to 11 GPM. Smaller homes can run on a 160,000 BTU unit.
Do I need a new gas line?
Often yes. Tankless units pull two to three times the BTU of a tank during peak demand. The existing line is often undersized.
Can I install one outdoors?
Yes, on outdoor-rated models. Outdoor install removes the venting cost but requires a freeze-protection circuit.

We had a serious issue with gas leaks and Sara’s Best Plumbing responded incredibly quickly. Their team, led by project manager Jessica, was at our house within two hours, which immediately helped ease a very stressful situation.
Susana Monteiro
Sara’s Best Plumbing installed a new water heater for us more than a year ago. The pipe on the top of it started leaking, so I called at 9am yesterday. They came out the same day and fixed the issue under warranty. No charge.
Vicki Bagley
Absolutely amazing. Extremely reliable and performs excellent work. We have had several complicated and difficult issues arise with our older home, and Sarah and her team have always been able to work with us and fix it.
Stephanie Marchione
Pedro was on time, efficient, and very professional. He explained the different components of my water heater, which helps for any future issues or changes I may want to make. Will definitely use Sara’s Best Plumbing in the future.
