Our Johnston Plumbing Services
Johnston homes depend on plumbing systems that function reliably every day, delivering clean water, removing wastewater, and protecting your property from leaks or flooding.
Johnston’s established neighborhoods mean mature trees and aging infrastructure that create unique plumbing demands. GEM services all major components of your plumbing system, including water heaters, drains, sump pumps, well pumps, and water treatment equipment.
Whether you’re facing an urgent leak or planning upgrades for improved performance, our technicians have the experience and tools to handle it right, backed by over 75 years serving Johnston and surrounding Rhode Island communities.
Emergency Plumbing Services
GEM provides around-the-clock emergency plumbing response throughout Johnston.
Burst pipes, overflowing fixtures, and sudden leaks don’t respect schedules. When water floods your basement or drains back up, a small leak can quickly escalate into major damage. Our licensed plumbers arrive equipped to contain the problem, fix it right, and protect your home from further harm. From water heater failures to sump pump problems and sewer backups, GEM responds when emergencies strike.
Plumbing Installation
Quality installation prevents leaks, pressure issues, and early system wear.
Proper installation means fewer callbacks and longer equipment life. We handle faucets, fixtures, water heaters, disposals, and complete repiping. Code compliance verified, pressure tested, ready to use.
Plumbing Repair
GEM fixes plumbing problems so Johnston homeowners can get back to their routines.
Leaky faucets, clogged drains, toilets that cycle constantly. Small annoyances become expensive problems when ignored. We diagnose the actual cause and fix it rather than treating symptoms.
Plumbing Maintenance
Regular maintenance keeps plumbing working properly and helps avoid surprise breakdowns.
Preventive care extends the life of water heaters, pipes, and fixtures. GEM plumbers check for hidden leaks, corrosion, pressure problems, and early wear. We clear drains, test water pressure, and confirm everything operates as designed.
Drain Cleaning
GEM clears blockages using camera inspection and hydro jetting technology.
Slow drains in Johnston often signal buildup deeper in your pipes. Grease, soap, hair, and debris accumulate until water struggles to pass. Mature trees in older neighborhoods can also send roots into sewer lines. We locate the obstruction, clear it completely, and restore proper flow.
- Hydrojetting: When drain snakes and plungers won’t cut it, high-pressure water cleaning blasts away grease, roots, mineral buildup, and stubborn clogs completely.
Water Treatment
Your Johnston family deserves clean, safe water at every faucet.
Water quality varies across the area, and many homeowners deal with hard water, odd tastes, or mineral deposits that damage plumbing over time. GEM helps families improve water quality with reliable treatment solutions. Whole-house filtration, water softening, we make better water simple.
- Water Purifier System Installation: When tap water tastes off, smells wrong, or looks cloudy, a purification system helps. GEM installs water filtration systems in Johnston that remove contaminants, chlorine, and sediment. We test your water and recommend the right solution for safe drinking water.
- Water Softener Installation: Hard water causes mineral buildup that damages pipes, stains fixtures, and shortens appliance life. GEM installs water softeners in Johnston that protect your plumbing while improving how water feels. We select the right model, install it correctly, and verify operation.
- Water Softener Maintenance: Softeners need periodic attention to keep producing results. We check salt levels, clean resin beds, inspect valves, and verify regeneration cycles work as designed.
- Water Softener Repair: Water spots returning to dishes, soap not lathering, scale building up again. These signs indicate softener problems. We troubleshoot the unit and restore proper operation.
- Water Softener Replacement: Old softeners eventually wear out. When repair costs approach replacement value, upgrading to a modern unit makes financial sense. Current models use less salt and water while performing better.

Additional Plumbing Services
Sump Pumps
High water tables along the Woonasquatucket corridor mean Johnston homeowners need sump pumps that work.
A functioning pump protects your home from flooding that causes thousands in damage. Whether you need new installation or service on your current pump, GEM provides expert sump pump care to keep basements dry.
- Sump Pump Installation: If your home lacks a sump pump or the current unit can’t handle heavy rain, GEM installs sump pumps in Johnston that deliver lasting protection. Our plumbers assess your basement, recommend appropriate capacity, and complete installation safely.
- Sump Pump Replacement: Pumps wear out after years of cycling on and off. Grinding noises, constant running, or failure to activate signal replacement time. We size the new unit properly and ensure backup power connection.
- Sump Pump Repair: When your pump stops working, basement flooding follows quickly. We respond fast to diagnose switch failures, motor problems, or discharge line blockages and get protection restored.
- Sump Pump Maintenance: Regular maintenance confirms your sump pump will work when flooding threatens. GEM’s service includes cleaning the pit, testing the float switch, checking backup power, and ensuring proper drainage. Routine care prevents failures and extends pump life.
Water Heaters
Few things disrupt your routine like losing hot water without warning.
Whether your water heater has failed or needs an upgrade, GEM provides expert installation, repair, and maintenance for traditional tank and tankless systems.
- Traditional Water Heater Installation: GEM installs tank water heaters in Johnston that deliver consistent hot water for your household. We evaluate your home’s size, usage, and efficiency goals to recommend the right model, then install it safely and to code.
- Traditional Water Heater Replacement: Water heaters over 10 years old, slow to recover, or showing corrosion usually warrant replacement. GEM simplifies upgrading by removing your old unit, installing an efficient new model, and ensuring proper connection for best performance.
- Traditional Water Heater Repair: Cold showers, rumbling tanks, water pooling on the floor. Water heater problems demand prompt attention. We identify the failure point and either repair or recommend replacement based on age and condition.
- Traditional Water Heater Maintenance: Sediment collects at the bottom of every tank. Anode rods corrode to protect the tank itself. Annual service addresses both issues and catches developing problems before they cause failures.
- Tankless Water Heater Installation: Tankless units deliver endless hot water on demand while using less space and energy. GEM installs tankless water heaters in Johnston sized to your home’s needs. We handle sizing, venting, setup, and testing so you enjoy unlimited hot water and lower bills.
- Tankless Water Heater Replacement: Tankless units eventually need replacing too. When yours starts underperforming or repair costs climb, newer models offer better efficiency and more precise temperature control.
- Tankless Water Heater Repair: Temperature swings, error codes flashing, unit shutting down mid-shower. Tankless systems have their own failure modes. We troubleshoot the electronics, gas supply, and heat exchanger to pinpoint issues.
- Tankless Water Heater Maintenance: Hard water scale builds up inside tankless heat exchangers. Annual descaling and filter cleaning maintains efficiency and prevents the mineral deposits that cause premature failure.
Well Pumps
Your well pump delivers the water your household needs daily.
When it fails, routines stop. GEM provides well pump installation and repair in Johnston and throughout Rhode Island to maintain reliable water supply for homes on private wells.
Septic Tanks
Homes with septic systems need regular care to avoid messy, expensive failures.
GEM provides complete septic tank installation, repair, maintenance, and replacement to keep your system working and protect your Johnston property.
Leak Detection
Hidden leaks in older Johnston homes can cause serious damage if not caught early.
Water escaping behind walls or under slabs causes damage you won’t notice until it’s extensive. Electronic detection equipment locates leaks precisely so repairs target the actual problem without tearing up your house.
Frozen Pipe Repair
Rhode Island winters can freeze pipes fast, especially in unprotected areas of your home.
Pipes running through uninsulated walls, basements, or crawl spaces are vulnerable during cold snaps. GEM provides frozen pipe repair in Johnston using professional thawing equipment to restore water flow safely and prevent burst pipes.
Sewer Lines
Mature trees and aging infrastructure in Johnston’s older neighborhoods can cause sewer line problems.
Tree roots, deteriorating materials, and outdated underground lines can force wastewater back into homes. GEM provides sewer line repair in Johnston using camera diagnostics to identify issues accurately and delivers repairs or replacements that restore proper flow.
Kitchen & Bath Remodel
Renovating a Johnston kitchen or bathroom requires skilled plumbing for new layouts and upgraded fixtures.
Renovations often require moving supply lines, rerouting drains, or adding fixtures. We coordinate with your contractor to handle the plumbing portion correctly the first time.
Garbage Disposals
Busy Johnston households rely on working garbage disposals for convenient kitchen cleanup.
Disposals handle food waste daily and eventually fail. Seized motors, persistent clogs, leaking seals. We repair units worth saving and replace those that aren’t.

Plumbing FAQs
When should I replace my water heater instead of repairing it?
If your water heater is over 10 years old, needs frequent repairs, or shows tank corrosion, replacement usually makes more sense. Rising energy bills and slow recovery times also suggest declining efficiency that a new unit would fix.
Why does my basement flood during spring thaw?
Johnston’s location along the Woonasquatucket corridor means high water tables that rise during wet seasons. If your sump pump can’t keep up or you lack one, water finds its way in. GEM can assess your basement and recommend drainage solutions.
How do I know if tree roots are in my sewer line?
Recurring drain backups, gurgling sounds, and slow drainage throughout the house often signal root intrusion. GEM uses camera inspections to confirm the problem and can clear roots with hydro jetting or recommend repairs for damaged sections.
Is tankless water heater installation worth the cost?
For many Johnston households, yes. Tankless units provide endless hot water, last longer than tank heaters, and use less energy. The upfront cost is higher, but lower operating costs and longer lifespan often make them worthwhile.
What maintenance does my plumbing actually need?
Annual inspections catch small problems before they grow expensive. Key maintenance includes water heater flushing, drain cleaning, checking supply lines, testing sump pumps, and inspecting visible pipes for corrosion or leaks.
