My tankless water heater was discharging water randomly. I had no idea what the issue was. But Sergio came by ASAP and helped diagnosed what could be the issue. It was determined that my water pressure regulator was broken and the water pressure was 140 psi. He replaced it with a new one the same day within an hour, and lowered the pressure to 50 psi, and no more water is discharging from my water heater anymore.Read review on Google
TANKLESS WATER HEATERS / GAS
Gas Tankless Water Heater Installation
PLAN THE FUEL, VENT, AND FLOW.
A gas tankless heater needs more than a water connection. Fuel capacity, venting, combustion air, clearances, and expected hot-water demand all affect the design. We review these conditions before an installation scope is proposed.

UNDERSTAND THE ISSUE
Planning Gas Tankless Water Heater Installation
A tank heater and a tankless heater may have different gas-input and venting requirements. The existing pipe size, meter capacity, vent route, termination location, condensate handling where applicable, and manufacturer clearances must be considered for the particular model. The goal is to plan a system that serves the home within its specified conditions, rather than assume the old connections will suit the new equipment.

WHAT WE'LL CHECK
Your Gas Tankless Water Heater Installation Options
We discuss fixture demand and inspect accessible water and gas connections, the proposed location, and the visible vent route. The chosen unit’s installation instructions and applicable requirements guide what must be confirmed, including whether fuel or vent modifications belong in the scope.
Install A Gas Tankless Heater
This can be considered when fuel supply, vent route, location, and the unit’s capacity can be matched to the household.
Compare Another Heater Design
A storage heater or another tankless configuration may be more practical when the gas line, vent path, or demand profile makes the first design unsuitable.

GOOD TO KNOW
Gas Tankless Water Heater Installation
Questions Answered.
Have a question about your plumbing? These answers cover what we’re often asked.
Can an existing gas tank heater vent be reused?
Not necessarily. Tankless equipment may have different venting requirements, so the route and materials must be checked for the selected model.
Will a gas tankless heater need a larger gas line?
It can. The existing pipe and available supply should be evaluated against the unit’s input requirements before installation.
What if I smell gas near the heater?
Leave the area and call the gas utility or emergency services from a safe location. Do not operate switches or manipulate the heater or gas controls.
Can I choose a tankless model before an assessment?
You can compare models, but capacity, fuel supply, venting, location, and local requirements should be confirmed before purchase.
