We also ensure proper pressure regulation and backflow prevention devices are installed where needed to protect your potable water supply.

Sump Pump and Sewage Ejector Pump Installation in Charleston
Protecting your Charleston home from water damage is important, especially in areas prone to heavy rains or with basements. GJK Plumbing installs reliable sump pumps to remove excess water from crawl spaces and basements. For homes with plumbing fixtures below the main sewer line, we also install robust sewage ejector pumps to safely move wastewater. Proper sizing and placement are key, and we ensure your pump has a dedicated circuit and correct discharge piping for optimal performance.
Tankless Water Heater Installation in Charleston, WV
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. Damp basements and crawlspaces are common in Charleston and around the state, which can speed up corrosion on pipes and fittings. We also install isolation valves for future flushing.
Backflow Preventer Installation in Charleston
Backflow preventers are essential for protecting your home's drinking water from contamination, especially for irrigation systems, fire suppression lines, or homes with private wells. GJK Plumbing installs and tests backflow prevention devices in Charleston to make sure your water supply remains safe and compliant with health codes. We ensure the correct type of device is installed for your specific application and that it is properly maintained and tested annually.
Water Softener Installation in Charleston, WV
Testing well water every year or so is a smart habit in West Virginia, especially after flooding or nearby ground disturbance. Hard water can damage appliances and leave mineral buildup. GJK Plumbing installs efficient water softener systems in Charleston, WV 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. Proper bypass valve installation and connection to your main water line are key for easy maintenance and effective operation.

Expansion Tank and Sewage Ejector Installs in Charleston, WV
Water heater expansion tanks absorb thermal expansion in closed systems, which protects pipes and relief valves. Homes with a pressure reducing valve often need one. We also install sewage ejector pumps for basements, guest suites and fixtures below the sewer line. These systems include a sealed basin, check valve and proper venting. Both installations protect your home from costly water damage.
