Gas Water Heater and Tankless Line Upgrades in New Haven, CT
Tankless water heaters often need up to 199,000 BTU, far more than the 40,000 BTU a typical tank heater uses. Many existing 1/2 inch lines cannot supply that demand, which causes error codes and lukewarm water. We calculate the full house load and upsize the line to 3/4 inch or larger as needed. This upgrade is one of the most important steps in a successful tankless conversion.

Gas Line Installation for Generators in New Haven
When installing a whole-home generator, a dedicated gas line is necessary for continuous power. We provide professional gas line installation to connect your generator to your home's gas supply. Our team ensures the line is correctly sized for the generator's BTU requirements and installed to withstand local conditions, providing reliable backup power for your New Haven property during outages.
Gas Range and Cooktop Line Installation in New Haven
Switching from an electric range to gas is one of the most frequent reasons homeowners call us. We run a dedicated branch from the nearest adequate supply, install a shutoff valve behind the range and connect with a new approved flexible connector. Professional-style ranges can need 60,000 BTU or more, so we confirm the branch and main can handle the load. The appliance is then checked for proper burner flame and ignition.
Whole-Home Gas System Installation in New Haven, CT
For new construction or major renovations, GLV Plumbing provides full whole-home gas system installation. We design and install the entire network of gas lines to supply all your gas-powered appliances. This includes main line connections, branch lines and shutoff valves at each appliance, for safe, even distribution throughout your New Haven property.
Outdoor Kitchen and BBQ Gas Lines in New Haven
Built-in grills, side burners and pizza ovens are a popular part of backyard living. We trench from the house to the island and install yellow polyethylene gas pipe with tracer wire, transitioning to steel above grade with an approved riser. Each appliance gets an accessible shutoff valve. We bury the line to code depth and protect it where it crosses landscaping or irrigation.
Pool and Spa Heater Gas Lines in New Haven
Pool heaters are among the largest gas appliances in a home, often rated at 250,000 to 400,000 BTU. They usually sit at the equipment pad far from the meter, so line size and length are crucial. We may recommend a larger main line or a meter upgrade from your gas utility. A properly sized line lets the heater reach its rated output and heat the water efficiently.
CSST Flexible Gas Piping in New Haven, CT
Corrugated stainless steel tubing installs faster than black iron and routes easily through attics and finished walls with fewer joints. It is a good option for remodels and additions where opening walls is costly. Heavy downpours can overload older sewer systems and push water back into basements, so a backwater valve can be a sensible upgrade. CSST must be bonded to the home's grounding system to reduce lightning damage risk. We use brands with fittings our plumbers are certified to install and follow the manufacturer's installation guide.

Flexible Gas Line (CSST) Installation in New Haven, CT
Corrugated stainless steel tubing offers a flexible, efficient option for gas line installation. GLV Plumbing is experienced with installing CSST, which can simplify routing and reduce the number of fittings compared to traditional black iron pipe. We ensure CSST is properly bonded and grounded, as Connecticut code requires, to protect against lightning and electrical surges in your New Haven home.
