A water-system proposal lands on the kitchen table with a softener, a filter, a drinking-water system and a new water heater on one page and one total at the bottom. It may all be needed, or it may not. The way to tell is to split the page into separate decisions, each tied to a problem someone has confirmed, before comparing prices.
Split the estimate into separate decisions
Water treatment, water heating and plumbing repair can share a basement while doing different jobs. A softener treats the water flowing through it to your fixtures. A water heater makes hot water. A boiler's heating circuit is separate from water delivered to your taps, but its fill-water requirements still matter. Check those requirements and the actual piping before linking a failure to household treatment. If a failed part isn't exposed to treated water, a treatment system can't be sold as its fix.
| Part of the estimate | What decides the cost | Ask for this in writing |
|---|---|---|
| Repair of a leak or failed equipment | The confirmed condition, access and parts | What failed, how it was confirmed and what the repair includes |
| Testing | The question being asked and the method that answers it | Sample point, method and whether a certified laboratory is involved |
| Water treatment | Test results, flow, plumbing, drain and power needs, and upkeep | The result it responds to, the exact model and its certified claims |
| Water heater | Fuel, capacity, venting or electrical work, condensate and access | Model, size, site work, removal and warranty terms |
| Optional upgrades | Your preferences | A separate price you can accept or decline |
Once the pieces are separate, you can approve one without assuming the rest are required.
Test before you buy treatment
What you see doesn't choose the equipment. White residue can prompt a hardness test, but appearance alone doesn't prove a softener is the answer, and staining, odor, taste and cloudiness each need a method suited to the concern. A TDS meter estimates total dissolved solids from conductivity; it doesn't identify them, measure PFAS or pick a treatment. PFAS and other health-related questions need a sample sent to a certified laboratory and collected the way that lab specifies. Our water testing process explains when a field check is enough and when it isn't.
Start with the source. The Town of Andover's 2025 Water Quality Report describes the public system; it is not a test of a particular home's faucet or a private well. MassDEP's private well guidelines address private supplies.
When results do point to treatment, each class changes the scope differently:
- Ion exchange (softening) is sized to measured hardness, household demand, drain capacity and salt use.
- Reverse osmosis at a kitchen sink adds a drain connection, often a storage tank, and scheduled filter and membrane changes.
- Oxidation/filtration is designed around laboratory results and needs backwash flow and a place for the waste water to go.
- UV needs power, a validated dose for the rated flow, clear water going in, and regular lamp and sleeve care.
- Activated carbon depends on the exact media, contact time and replacement schedule.
- No treatment stays on the table when results point to plumbing repair, maintenance, more testing or no change.
A model can be credited with reducing a specific contaminant only when that exact model is certified for it. NSF's overview of treatment standards explains the difference between aesthetic claims and health-effect claims, and NSF's certification directory is where to check a model's listing. Our test-first water treatment service starts from the results.
What water heaters cost
Water heaters are easier to price because Jeneral Plumbing publishes installed prices for each type:
| Water heater type | Installed price |
|---|---|
| Standard electric resistance tank | From $2,300 |
| Gas storage tank, all vent types | $2,900 – $6,500 |
| Hybrid heat pump | Up to $7,800, before the Mass Save incentive below |
| Condensing tankless | $8,500 – $11,000+ |
Those aren't interchangeable bids. Fuel changes, venting, gas supply, electrical capacity, condensate drainage, tank size, access, permits and removal decide where a project lands. A hybrid heat pump model also needs the right room; ENERGY STAR's design guidance covers airflow, room temperature, sound, cooler discharge air and service access. Our water heater repair and replacement guide compares the options.
As of September 2026, Mass Save lists a $750-per-unit incentive for qualifying tank-style ENERGY STAR-certified heat pump water heaters. Other configurations have different terms. The program administrator decides eligibility, and the terms can change, so recheck the exact model and current requirements before you order. A good proposal shows the price before the incentive and the incentive separately, so you know the cost if the application isn't approved.
What a complete quote includes
Jeneral Plumbing prices repair and installation work at a flat rate, with the total and any applicable fees disclosed for approval before work begins. Whoever you hire, a quote you can compare should name the equipment or repair, access assumptions, plumbing changes, drainage, venting or electrical responsibility, permits, startup and testing, removal and exclusions. For treatment, add the test result it responds to, the design flow, the exact model, consumables and who maintains it. For water heaters, add capacity, fuel, condensate handling, warranty boundaries and any dated incentive assumptions.
Two quotes aren't comparable when one includes site work and the other leaves it vague. Ask whether existing piping is reused, whether a drain or circuit is included and who restores finishes. Be wary of promised savings, equipment lifespans or health outcomes that no one can verify for your house. And keep the order straight: stop active leaks and restore failed essential equipment first, then test, then weigh optional treatment as its own decision.
Andover and the towns we serve
Jeneral Plumbing is owner-operated by a Licensed Master Plumber (MA #9628831-PL-M), based in Westford, MA, and serves homes within 20 miles across Middlesex & Worcester County and southern New Hampshire. We do not offer New Hampshire fuel-gas fitting. Our service-area directory provides local coverage guidance, including neighboring Tewksbury and Wilmington. The approach above works anywhere.
Call (978) 392-7789 with your address, water source, the equipment you have, any test reports and the proposal you're weighing. Before booking, we'll confirm the address is within our 20-mile service area, whether the requested work fits our scope and our availability. A regular-hours visit carries an $80 dispatch fee — the cost of the visit, waived when you hire us for the work. For softeners and filters specifically, our filtration and softener service covers inspection, repair and installation once the need is established.
