Float Switch and Check Valve Replacement in Medford
Many sump pump failures start with a stuck float switch or a leaking check valve. A failed check valve lets water flow back into the pit and causes the pump to short cycle. We install new check valves with every pump replacement and verify the switch moves freely. Vertical float switches work well in tight pits. Tethered floats suit larger pits.

Commercial Pit Pump Replacement in Medford
Commercial buildings often have elevator pits, parking garage drains and mechanical room sumps. These require pumps rated for higher flow and sometimes oil-sensing controls. We replace commercial pumps and alarms to meet code and insurance requirements. Duplex systems with alternating pumps provide a backup. We schedule work to avoid interrupting operations.
Battery Backup Sump Pump Installation in Medford
Power outages during severe storms can leave a primary sump pump useless, leading to basement flooding. A battery backup sump pump offers crucial protection during these times. We install and replace complete battery backup systems, including dedicated marine-grade batteries and smart charging units. Our team helps you select a system with enough run-time to protect your Medford home through extended power interruptions. You get peace of mind when the lights go out.
Battery Backup Sump Pump System Installation in Medford
Snowmelt combined with rain is a common recipe for wet basements, overworked sump pumps and municipal sewer backups. Power outages during severe storms can leave standard sump pumps useless. Our battery backup sump pump system installation in Medford provides an essential layer of protection. We add a secondary, battery-powered pump that automatically activates if the primary power fails, keeping flood protection running even without electricity. This is a valuable upgrade for many homes.
Sewage Ejector Pump Replacement in Medford
Basement bathrooms and laundry rooms below the sewer line need sewage ejector pumps instead of sump pumps. These pumps handle solids and must be installed in sealed, vented basins. We replace ejector pumps with models rated for two inch solids. We also check the basin seal, vent and discharge check valve. Proper installation stops sewer gas odors.
Yard Drainage Pit Pumps in Medford, MA
Some properties use pumps in yard drainage pits or below-grade window wells to handle storm runoff. These pumps may sit idle for months, then fail when they are needed most. We replace them with corrosion-resistant models and clear debris from the pit. We can route discharge away from foundations and onto approved areas. Regular testing before storm season is a good habit.
High-Capacity Sump Pump Upgrades in Medford
If your current sump pump struggles to keep up with heavy water flow, especially during intense thunderstorms, it may be undersized. We offer high-capacity sump pump replacements and upgrades designed to handle large water volumes. Our plumbers will assess your water intrusion patterns and recommend a pump with greater horsepower and a higher GPM (gallons per minute) rating. This prevents the pump from cycling too frequently or failing under stress, common issues in some Medford properties.

Sump Pump Basin and Pit Replacement in Medford, MA
Sometimes it is not just the pump that needs replacing, since the sump basin or pit itself might be cracked, damaged or too small. BWM Plumbing offers sump pump basin and pit replacement in Medford, MA so your entire system works properly. A properly sized and intact pit is important for the efficient operation and longevity of your new sump pump.

Frequently Asked Questions About Sump Pump Replacement in Medford
The cost of sump pump replacement in Medford, MA usually ranges from $500 to $1,500, depending on the type of pump, submersible or pedestal, its horsepower and any needed pit changes. Battery backup systems will add to this cost, usually between $300 and $800. We provide a detailed, upfront quote after assessing your needs.
Most sump pump replacements take one to two hours. Battery backups or new discharge lines take a bit longer.
A primary sump pump is your main defense against basement flooding, powered by your home's electricity. A backup sump pump, usually battery-powered or water-powered, is a secondary system that activates if the primary pump fails, loses power or cannot keep up with heavy water inflow. Many Medford homes benefit from a backup system due to storm risks.
Most standard sump pump replacements can be completed within 2 to 4 hours. More complex installations, such as those requiring new pit excavation or extensive discharge line work, might take longer, up to a full day.
Most sump pumps last 7 to 10 years. Pumps that sit idle for long periods can fail sooner due to stuck switches.
A battery backup sump pump system is a secondary pump powered by a battery, designed to activate automatically if your primary sump pump loses power during an outage or fails. This is important for maintaining flood protection during power outages caused by severe weather.
BWM Plumbing provides warranty coverage on both the sump pump unit itself, per the manufacturer's warranty, and our workmanship. We stand behind our installations for your peace of mind and a reliable, long-lasting solution.
