What drives the price
The unit is half; the plumbing is the rest. Homes with a softener loop already stubbed in are quick; without one, the main line gets cut and rerouted, a drain and power must be within reach, and Florida homes plumbed through the slab can make that run genuinely awkward.
- Existing softener loop vs cutting into the main
- Grain capacity sized to household and hardness
- Salt-based softening vs salt-free conditioning - different products, different claims
- Drain routing - air gap requirements catch garages without one
- Dealer-brand units vs equivalent hardware at retail
Should you DIY this or call a professional?
Call a plumber unless a loop exists and you sweat pipe happily. The meaningful money decision is upstream of installation: dealer road-show units at $4,000-$7,000 are routinely the same resin-tank technology as $700 retail units - the difference is the sales commission. Test your actual hardness first ($10 strips) and size from that.
Signs you need this repair
- Scale crusting faucets and shower glass
- Water heater efficiency falling - sediment popping and rumbling
- Soap that will not lather, stiff laundry
- Appliance manuals voiding warranty above a hardness you exceed
How to not get overcharged
Get the hardness number and the grain size on the quote, then compare the installed price against a retail unit plus a plumber's install rate - the spread is often thousands for identical function. Ask what the valve brand is (the valve is what fails; Clack and Fleck are the serviceable standards) and whether the drain install meets code with an air gap - the shortcut version backs sewage into your softener.

Red flags to watch for
- In-home 'free water tests' that end in a four-figure contract that evening
- No hardness number anywhere on the quote
- Proprietary valves only the dealer can service
- Claims a softener removes bacteria or 'toxins' - it removes minerals
