The Benefits of Soft Water
Installing a whole-home water softener system does more than just improve the feel of your water. It protects your investment.
- Longer Appliance Life: Prevents scale from destroying water heaters and dishwashers.
- Cleaner Dishes: Eliminates cloudy spots on glassware.
- Better Lather: Soaps and shampoos work more effectively, meaning you use less.
- Protected Pipes: Reduces mineral accumulation inside your plumbing lines.
We offer water testing to determine the hardness level of your water and recommend a softener system that fits your household’s specific needs.
Sump Pump and Well Pump Services
In Indiana, managing ground water is critical to protecting your home. A reliable sump pump is your basement’s first line of defense against flooding during heavy rains.
Sump Pump Maintenance
You often don't know your sump pump has failed until you are standing in water. We recommend regular testing and battery backup installation to ensure your pump activates when the power goes out during a storm. Our team installs high-quality primary and backup sump pumps to keep your lower levels dry.
Well Pump Expertise
For homes that rely on private wells, the well pump is the heart of the water system. If you are experiencing low water pressure, sputtering faucets, or no water at all, our technicians can diagnose the issue. We repair and replace well pumps, pressure tanks, and switches to restore reliable water delivery to your home.
Frequently Asked Questions
It is generally a good idea to schedule professional drain cleaning every 18 to 24 months as a preventative measure. However, if you have a large household or older pipes, you might benefit from annual inspections to prevent major backups.
A sudden increase in your water bill usually indicates a leak. This could be a running toilet (which can waste thousands of gallons a month), a dripping faucet, or a hidden leak in your water line. If you cannot find the source, our technicians can perform a thorough inspection to locate and repair the leak.
Popping or rumbling noises in a water heater are typically caused by sediment buildup at the bottom of the tank. As the burner heats the water trapped under the sediment, it bubbles up and disturbs the layer of debris. Flushing the tank usually resolves this issue.
