Sizing and Water Assessment

Not sure what you need? We assess your water quality, mineral content, and household demand and recommend the right solution — a softener, or where taste and contaminants are the concern, a filtration option — based on what your water actually needs.

Our Water Softener Installation Process

Installing a water softener involves connecting components like the resin tank and brine tank into your main water line, and doing it to code.
Here’s how a proper installation process goes:

Step 01

Find the Best Location

The first step is choosing the best location — usually the utility room or garage near where the main water line enters the home, with an electrical outlet nearby and space for the tanks and for maintenance access.

Step 02

Shut Off and Drain

We turn off the main water supply valve and drain all faucets to relieve pressure and remove water from the plumbing system before cutting into the line.

Step 03

Cut In and Connect

We cut the main water line and install bypass valves, then connect the water softener unit to the inlet side using compression fittings, with flexible supply hoses recommended for the connections to the softener. The right tools and materials make this a clean, leak-free tie-in.

Step 04

Flush, Test, and Verify

We flush the system after installation to remove particles and debris, then a proper water softener installation includes checking for leaks after connecting the system and confirming water flow at your fixtures. We walk you through operation and maintenance before we leave.

Frequently Asked Questions

Largo’s water runs roughly 10 to 15 grains per gallon — around 12 to 13 on average — which is classified as hard. That’s enough to scale pipes and appliances, spot glassware, and leave film on fixtures. A water softener treats it at the point of entry, so the whole home gets softer water.

We start by testing your water and sizing the unit to your hardness reading and household demand — an undersized system won’t keep up and an oversized one wastes salt. From there, we shut off the main, tie the softener into the supply line after the meter (and ahead of the water heater), run a dedicated drain line for regeneration backwash with the required air gap, and add a bypass valve so the house still has water during service.

Then we program the regeneration cycle for your water, pressure-test the connections, and confirm you’re getting soft water at the tap before we leave. Every part of that is done to code, which is what separates a professional install from a hardware-store DIY that leaks or never regenerates right.

Possibly. Because a softener ties into your main water supply, local building codes may require a permit. We verify the current local requirement, pull any permit needed, and handle the inspection so the installation is code-compliant.

A straightforward installation is usually done in a few hours, depending on the plumbing at your entry point and whether an electrical outlet and drain are already nearby. We give you a written price after assessing your setup, so you know the cost before any work starts.

The most common cause is a salt bridge — a hardened crust in the brine tank that keeps the salt from dissolving. Clogged lines, a stuck valve, or worn-out resin are other culprits. Most repairs take one to two hours once we find the cause.

It depends on the unit’s age and what failed. A salt bridge or a valve issue is usually worth repairing. An old unit that keeps failing is often cheaper to replace than to keep fixing. We give you an honest read on both.

A softener runs your incoming water supply through a resin tank filled with resin beads that capture the calcium and magnesium responsible for hardness. A separate brine tank periodically regenerates those beads with a salt solution so the system keeps working. Installed on the main water line at the entry point to the home, it softens water for the entire home — every fixture and every appliance downstream benefits.

Because the softener sits on the main water supply, a bypass valve is built into the installation so the system can be serviced without shutting off the home’s water supply entirely. Getting that plumbing right — the water supply line connections, the bypass, and the drain — is what separates a clean professional installation from a leaky one.
