Water Line Installation in New Haven
Whether you're replacing old, corroded galvanized pipes or installing new water lines for an addition, GLV Plumbing has you covered. We work with various materials like PEX and copper, ensuring durable, leak-free connections. Hard water can lead to mineral buildup, making proper pipe selection and installation crucial for longevity. Public water in most of Connecticut runs soft to moderately hard, and soft water can be mildly corrosive to older copper plumbing. We handle everything from the main water service line into your home to individual fixture supply lines, following all local regulations for trenching, backfilling, and pressure testing.

Water Line Installation and Replacement in New Haven
From replacing old, corroded pipes to installing new water lines for additions or renovations, GLV Plumbing provides complete water line installation in New Haven. We work with various materials, including PEX and copper, making durable, leak-free connections. Most homes here have full basements, so sump pumps, floor drains, and foundation seepage are frequent plumbing concerns. We use bedding and burial techniques that reduce future issues with buried lines. We also ensure proper pressure regulation and backflow prevention devices are installed where needed to protect your potable water supply.
Tankless Water Heater Installation in New Haven, CT
Tankless water heaters from Navien, Rinnai and Rheem deliver endless hot water and save space in garages and closets. Gas units usually need a larger gas line and new venting, while electric units often need added amperage. We size the unit by flow rate and incoming water temperature. Seasonal swings from freezing winters to muggy summers expand and contract pipes, which can loosen aging joints over the years. We also install isolation valves for future descaling.
Water Heater Installation in New Haven
GLV Plumbing specializes in installing all types of water heaters, including conventional tank models and advanced tankless units, for homes in New Haven. We help you choose the right size and energy source, gas or electric, to meet your family's hot water demands and budget. Proper venting and connection to existing lines are critical for safety and efficiency, especially with gas units, and our certified plumbers ensure a clean setup. We also handle the safe disposal of your old unit.
Sewage Ejector Pump Installation in New Haven, CT
When plumbing fixtures are located below the main sewer line, such as in a basement bathroom or laundry room, a sewage ejector pump is necessary. GLV Plumbing provides professional sewage ejector pump installation in New Haven, CT. We confirm correct sizing of the pump and basin, proper venting, and secure discharge line connection to the main sewer. This complex installation requires specialized knowledge to prevent backups and ensure reliable waste removal. We use durable pumps from trusted brands like Liberty Pumps or Zoeller to guarantee long-term performance.
Sump Pump Installation in New Haven, CT
Protecting your basement from flooding is essential in New Haven, CT, especially during heavy rainfalls. GLV Plumbing provides professional sump pump installation, including primary and battery-backup systems. We evaluate your basement's water intrusion risks, soil conditions, and foundation type to recommend the right pump capacity and discharge setup. Proper pit excavation, check valve installation, and discharge line routing away from your foundation are key steps we manage carefully. Our team makes sure your new sump pump is ready to handle any excess water, preventing costly damage.
PEX Pipe Installation and Repiping in New Haven
PEX is flexible, resistant to scale and a popular choice for repiping older homes with failing copper or galvanized pipe. We install PEX with manifold or home-run layouts for balanced pressure. The material handles hard water well and can reduce noise in the walls. We patch access openings neatly or coordinate with your drywall contractor. A PEX repipe can stop recurring pinhole leaks.

Water Softener Installation in New Haven, CT
Public water in most of Connecticut runs soft to moderately hard, and soft water can be slightly corrosive to older copper plumbing. Hard water can damage appliances and leave mineral buildup. GLV Plumbing installs effective water softener systems in New Haven, CT to protect your plumbing and improve water quality. We assess your home's water hardness and usage to recommend the right system, whether it is a salt-based ion exchange or a salt-free conditioner.

Frequently Asked Questions About Plumbing Installation in New Haven
Costs depend on the project. A standard tank water heater install usually runs $1,600 to $3,500, a water softener $1,500 to $4,000, and a whole-home PEX repipe $5,000 to $15,000 or more depending on home size.
A sump pump is designed to remove clear groundwater that collects in a sump pit, usually in a basement or crawl space, to prevent flooding.

Yes, we install rough-in and finish plumbing for additions, remodels and light commercial projects. We coordinate with your builder or general contractor.
In New Haven, most backflow preventers are required to be tested annually by a certified technician to confirm they are functioning correctly. This is crucial for maintaining the safety of your public water supply. GLV Plumbing offers convenient annual testing and certification services.
GLV Plumbing installs a wide range of trusted brands, including Moen, Delta, Kohler for fixtures, Rheem, Bradford White, and Rinnai for water heaters, and Zoeller or Liberty Pumps for sump and ejector pumps. We can also install client-supplied products, ensuring they meet quality and code standards.
You should consider replacing your main water line if you experience consistently low water pressure, recurring leaks, discolored water, or an unusually high water bill that cannot be attributed to other issues. Older homes in New Haven often have aging galvanized or polybutylene pipes that are prone to failure, making replacement a wise investment.
We install Rheem, A.O. Smith, Bradford White, Navien, Rinnai, Fleck and other trusted brands. We recommend models based on your home and budget.
PEX (cross-linked polyethylene) is a flexible plastic tubing used for water supply lines. It's popular for installations in New Haven because it's corrosion-resistant, less prone to bursting from freezing than copper, and often quicker to install. Its flexibility allows for fewer fittings, reducing potential leak points and making it a dependable choice for Connecticut homes.
