Why homeowners choose ESP for this
Why a private well and septic changes the plumbing
Drive past the edge of the villages in Nassau, Rensselaer and Columbia County and the municipal water main, the natural-gas line and the public sewer all run out. The homes out there make their own water from a private well and treat their own waste through an on-site septic system. That is a completely different plumbing job than a house in town — there is no water department to call when the pressure drops and no city sewer to absorb a bad day. The whole system is on your property, and it is on you.
That is the work ESP does every week. We service and replace well pumps and pressure tanks, diagnose and fix the well water itself — the acidic, iron-stained, sulfur-smelling, hard water that’s normal for this region’s aquifers — and we install and repair fixtures and drains the right way so they’re easy on the septic field that has to digest everything that leaves the house. One licensed crew that understands both halves: the water coming in, and the water going out.
We’re a family-run shop based in Nassau, working the rural roads other companies skip. When something on your well or septic side acts up, a licensed ESP tech comes out for a free in-home assessment and tells you straight what’s going on — no upsell, no guesswork.
Why rural homeowners call ESP for well and septic work
This is more than a quick fix. Here is what a local crew that does this every week brings to your home.
We test before we sell
Well water is different on every road. We test your actual water — pH, iron, hardness, sulfur, bacteria — and size treatment to your results, not to a generic package or a number off a web page.
Both halves, one crew
Water coming in and water going out are one system on a rural home. We handle the well-pump and pressure-tank side and the septic-safe fixture and drain side, so you're not juggling two contractors.
We drive the rural roads
Wells and septic mean you're usually off the beaten path. Covering the back roads of Nassau, Rensselaer and Columbia County is our normal route, not a special trip.
Septic-smart, not just fast
We fix drains and install fixtures with your septic field in mind, because the field is the expensive part you can't easily replace. The right repair protects the whole system.
What we handle on a well-and-septic home
Private wells around here pull from shallow aquifers, and the water comes up with character: it’s often slightly acidic (low pH), which slowly eats copper and galvanized pipe and leaves blue-green staining; it carries iron and manganese that rust-stain sinks, tubs and laundry; and it can come up with a rotten-egg sulfur smell from hydrogen sulfide. Hardness from dissolved minerals scales up water heaters, fixtures and tankless coils. The exact mix is different on every road and every depth of well, so we test your water before we recommend a thing.
On the waste side, these same homes run on septic — there’s no municipal sewer or treatment plant out here, so every drain in the house empties to a tank and a drain field on your own land. That means the fixtures, the drains and what goes down them all have to be chosen and maintained with that septic system in mind, because the field is the part you can’t easily replace.
Well & water quality
Test the water before you treat it
Every well is different, so we never guess. We pull a water sample, test for hardness, iron, sulfur and sediment, then size the right treatment for your home and put the price in writing — no upsell.
- A real water test, not a sales pitch
- Right-sized softener or filtration for your well
- Pump, tank and treatment financed monthly
Septic and on-site systems welcome — we work on rural homes every week across Rensselaer, Columbia and the eastern Capital Region.
Well pump & pressure tank
No water or short-cycling pressure usually means a failing pump or a waterlogged tank. We diagnose, repair and replace submersible and jet pumps and pressure tanks.
Water softening & filtration
Hard water, iron staining, sulfur smell or sediment — we test your well water and fit the right NSF-certified softener or filtration, point-of-use or whole-home.
Septic & sewer line care
On a septic home a slow or backing-up line is urgent. We camera the lateral, clear roots and grease, and repair or replace failing drain and sewer line.
Schedule your free in-home assessment
A licensed ESP tech reviews your home and your current setup, then quotes the right fix or upgrade in writing, with no obligation.
Treat the well water, or just live with it?
No pressure either way, just an honest look at your system. Here is the quick read on when a replacement pays off and when a repair still makes sense.
A flat price up front, after we test
Well and septic work is the kind of thing you want priced for your house, not guessed off a chart, because the right answer depends on what your water test shows and what your system actually needs. We won’t print a figure on a web page — the honest number is the one we measure on site.
The price for water treatment depends on what’s in your water (acid neutralizer, iron filter, softener, carbon, UV — or some combination) and on your home’s flow. Pump and pressure-tank work depends on your well depth and setup. Either way, you get a flat, written quote with no surprises before any work is scheduled.
The financing spreads a bigger job — a full treatment system or a pump replacement — over low monthly payments through Acorn Finance, with $0-down and low-rate options for qualified buyers. See current terms on our financing page.
How a well-and-septic visit works
From the first visit and water test to a clean inspection, here is what working with ESP looks like.
Free in-home assessment & water test
A licensed tech looks over your well, pump, pressure tank and septic-side fixtures, and tests your water so we're working from facts, not symptoms.
Options & price in writing
You get your real options — treatment, pump or fixture work — with a flat written price and Acorn Finance monthly payments laid out side by side. No pressure.
Permitted, code-compliant work
We pull any well, septic or county health-department permits the job needs, do the work to code, and clean up after ourselves.
Test, walkthrough & sign-off
We confirm the fix — re-test treated water or check pressure and drainage — see the job through inspection where required, and walk you through how it all works.

Well pump and pressure tank problems
On a well, the pump and pressure tank are your water supply. These are the signs that something there is failing.
Pressure swings or a pump that never stops
A waterlogged pressure tank, a failing pressure switch or a worn pump makes the pump cycle on and off quickly or run without building pressure.
Sputtering faucets or air in the lines
Air at the tap can mean a leak on the suction side, a falling water level or a pump struggling to prime.
No water at all
Check the breaker first. If it is on and there is still no water, the pump, the pressure switch or the wiring may be at fault.
A higher electric bill
A pump that runs far more than it should uses more power, and the bill can be the first sign.
Signs a septic problem is backing up into the house
The septic work on this page is the plumbing side: drains, fixtures, the lateral line and sewer line repair. Septic tank pumping and drain-field work are not part of the services listed here. Call and we will tell you whether we can help.
These signs often mean it is time to have someone look.
Wastewater surfacing over the tank or field is a septic contractor’s job. The camera check of the line to the tank is ours.
Slow drains in more than one place
One slow sink is usually a local clog. Slow tubs, sinks and toilets together can point to the main line or the tank.
Gurgling and backups
Gurgling pipes, toilets that bubble when the washer drains or sewage backing up into the lowest drain are common warning signs.
Odors indoors or outdoors
A sewage smell near the drains or over the tank and field means something is not draining as it should.
Wet or unusually green ground
Soggy patches or lush grass over the field can mean wastewater is surfacing. Keep children and pets away and call.
Well water and septic services: where the plumbing side fits
In our own records, 13.6% of the 921 main-line and sewer-related drain calls from October 2021 to October 2026 mention a septic system. Tank pumping and drain-field work are done by septic contractors, not by us. What we do is the plumbing between the house and the tank: drains, fixtures and the sewer line.
Septic-safe fixtures and drains
Fixtures and drains set up so the water they send out is gentle on the tank and the field, with no harsh chemical drain openers.
Lateral and sewer line
A blocked or broken line between the house and the tank is plumbing, and a camera look shows where. See sewer camera inspection.
Questions we hear
Well water & septic FAQ
Straight answers for Capital Region homeowners on a private well and septic.

Yes — it’s a big part of what we do across the rural Capital Region. Out past the villages in Nassau, Rensselaer and Columbia County, most homes run on a private well and an on-site septic system, and we service both: well pumps and pressure tanks, whole-home water treatment, and septic-safe fixtures and drains. Call (518) 482-4205 Monday through Friday, 7:30am–6pm, and we’ll get a licensed tech out.
No. Septic tank pumping, inspection of the tank and drain-field repair are done by septic contractors. We handle the plumbing side: drains, fixtures, the lateral and sewer line, and a camera look at the line before any digging. If you are not sure which one you need, call and we will tell you straight whether we can help. See sewer camera inspection.
Usually, yes. That rotten-egg smell is hydrogen sulfide, and it’s common in well water around here. We test your water to confirm the cause, then size the right treatment — often a carbon, oxidizing or aeration system — to take the odor out. We don’t guess: the fix follows the test results, and you get a flat written price before any work is scheduled.
A common guideline is every three to five years, but it depends on the size of the tank and how many people use it. A household that runs a garbage disposal heavily or has a small tank may need it sooner. Tank pumping is done by a septic contractor, not by us; the county health department or your contractor can tell you your interval.
Two different things, both normal for this region’s wells. Rust-colored stains are iron and manganese coming up with the water. The blue-green staining means your water is slightly acidic (low pH) and is slowly leaching copper out of your pipes — which is worth treating before it wears the plumbing thin. We test for both and recommend an iron filter, an acid neutralizer, or whatever your specific water actually needs.
Watch for pressure that swings or drops, a pump that runs without stopping or cycles on and off quickly, sputtering faucets, cloudy or sandy water and a rising electric bill. A waterlogged pressure tank or a bad pressure switch causes many of the same signs as a failing pump, which is why we test the whole system before replacing anything.
A softener tackles hardness — the dissolved minerals that scale up your water heater, tankless coil and fixtures. Filtration and treatment handle the other stuff: iron and manganese staining, sulfur odor, sediment, low pH and bacteria. Many rural homes here need a combination, which is exactly why we test the water first and build the system around your results instead of selling a one-size box.
A yearly test is a sensible baseline, with a lab test for bacteria and nitrates, and a retest whenever the taste, smell or color changes or after any work on the well. Treatment equipment is chosen from the results, not from a brochure. Our well water treatment guide explains what each result means.
Yes. A septic system relies on the bacteria in the tank breaking things down, so harsh chemicals, grease, “flushable” wipes, paper towels and excess food waste all work against it and can shorten the life of your drain field. We can set up your fixtures and drains to be easy on the septic side and point out the habits that protect the field — the part of the system you really don’t want to replace.
Ask for these in writing: a New York license and proof of insurance, a clear scope that says whether tank pumping is part of the job, a camera look at the line before any digging, and a flat price before work starts. See our licenses and insurance.
On a well system that usually points to the pump, the pressure tank or the pressure switch — a waterlogged tank, a failing switch or a tired pump will all cause weak pressure or a pump that won’t stop cycling. We diagnose the whole well setup, not just the obvious part, and fix or replace what’s actually failing. Call (518) 482-4205 and we’ll get a tech out, with same-day visits available Monday through Friday.
Yes. Our shop is in the town of Nassau, in Rensselaer County, and Schodack is in the same county. For local detail, see plumbing in Schodack and drain and sewer service in Schodack, or well water treatment.
Yes. A full water-treatment system, a pump or pressure-tank replacement or a repipe can be financed through Acorn Finance, with zero-down and low-rate options for qualified buyers, which turns the cost into low monthly payments. Current terms are on our financing page.
