Solution For Every Drop

Multi-stage water filtration system installed under a sink

Water Conditioners

Water conditioners treat hard water without the salt and regeneration cycle of a traditional softener, which some homeowners prefer for maintenance or environmental reasons. We’ll walk you through how conditioning compares to softening for your specific water so you can choose the right fit. Installation is clean, and we make sure the system is sized correctly for your household.

Water Softeners

Hard water leaves scale on fixtures, shortens the life of appliances, and can leave skin and hair feeling dry. Our water softener systems remove the minerals causing the problem, protecting your plumbing and appliances for the long haul. We handle sizing, installation, and ongoing service so soft water is one less thing to think about.

Reverse Osmosis

For water that’s cleaner at the tap, our reverse osmosis systems filter out sediment, chemicals, and dissolved solids that standard filtration can miss. It’s a popular choice for drinking and cooking water throughout the home. We install and service RO systems sized to fit under your sink or serve your whole house.

Water Filtration

Every home’s water is different, and a good filtration system starts with knowing what’s actually in yours. We test your water, identify what needs to be filtered out, and install a system built for your specific needs. The result is better-tasting, better-smelling water straight from the tap.

Water Treatment

Beyond filtration and softening, we offer treatment solutions for iron, sulfur, bacteria, and other issues specific to well and municipal water. Our team diagnoses the root cause first, then recommends the right treatment rather than a one-size-fits-all system. It’s water quality work built around your home, not a generic package.

Water Softener Installation in Decatur, IN

Andrews Plumbing installs and services water softeners, water conditioners, reverse osmosis, and whole-house filtration for homes and businesses in Decatur, IN and across Northeast Indiana and Northwest Ohio. We test your water first, then size and install a system that fits what is actually in it, whether you are on city water or a private well.

Hard water is common across Northeast Indiana, and many rural homes in Adams and Wells Counties draw from private wells that can also carry iron, sulfur, or sediment. Left untreated, these minerals build scale inside water heaters, stain fixtures, and shorten the life of appliances. A properly sized softener or treatment system protects your plumbing and makes your water better to drink and bathe in.

Frequently Asked Questions

Is my water quality actually a problem if it looks and tastes fine?

Not all water issues are visible or noticeable by taste. Hard water, chlorine byproducts, and certain minerals can affect your plumbing and appliances long before you notice a change in taste or clarity. A water quality test can identify what's actually in your water, even when it looks clean.

What's the difference between a whole-house filter and an under-sink unit?

A whole-house system treats all the water entering your home, protecting pipes, water heaters, and every fixture from sediment, chlorine, or hard water buildup. An under-sink unit targets drinking and cooking water at a single tap. Many homes use both: whole-house protection plus a dedicated drinking water solution.

Will a filtration system work with well water?

Yes. Well water often carries different concerns than municipal water, including iron, sulfur, sediment, or bacteria. Systems can be customized based on a water test to address exactly what's present in your specific well source.

How long does installation take?

Most filtration and treatment system installations are completed in a single visit, with minimal disruption to your household. The exact timeline depends on the system type and your home's existing plumbing setup.

Do filtration systems require ongoing maintenance?

Yes, most systems need periodic filter changes, salt refills (for softeners), or tank servicing to keep performing effectively. Maintenance schedules vary by system type and household water usage.

How do I know which system is right for my home?

The right system depends on your water source, water test results, household size, and specific concerns (hardness, taste, odor, contaminants). A professional evaluation is the most reliable way to match a system to your actual water conditions rather than guessing.

Is bottled water a better option than a home filtration system?

Whole-home filtration is generally more cost-effective and environmentally friendly long-term, since it treats water at every tap rather than requiring ongoing bottled water purchases, and it also protects pipes and appliances that bottled water can't help with.

Can a water filtration system help with skin or hair irritation caused by hard water?

Yes. Hard water minerals can strip natural oils from skin and hair, leaving them dry or irritated. A water softener or filtration system reduces mineral content, which often improves how water feels for bathing and showering in addition to protecting pipes and appliances.

Do you install water softeners in Decatur, IN?

Yes. Andrews Plumbing is based at 2009 Patterson Street in Decatur, IN, and installs and services water softeners, conditioners, reverse osmosis, and filtration systems throughout Adams, Wells, and Allen Counties and Northwest Ohio. Call (260) 202-0286 to schedule a water quality evaluation.

Do I need a water softener if I have well water in Adams County?

Many private wells in Northeast Indiana produce hard water, and some also carry iron or sulfur. A water test is the only way to know for sure. We test your water first and only recommend a softener or treatment system if your results call for one.
