What a water feature visit includes
Fountains need balanced water and working circulation just as pools do, even though nobody swims in them. Organic debris, bacteria and anything visitors toss in all affect the water. An imbalance leads to algae, staining and wear on pumps, filters and motors. A visit balances the chemistry, clears debris and stains and inspects the circulation and filtration system. The work runs from top to bottom so a clog in one tier does not undo the cleaning below it. Cleaning methods are matched to the materials, because natural stone, liners and features with LED lighting each need a different touch. Residential features, commercial fountains and waterfalls or spillways built into a pool are all covered.
Phosphate in local fill water
Shallow moving water in full sun is an easy place for algae to start. The fill water can give it a head start. The UNH/Durham system adds an orthophosphate corrosion inhibitor, according to its 2025 Water Quality Report. Dover's 2026 report lists zinc orthophosphate for corrosion control. Portsmouth's 2025 report shows orthophosphate averaging 1.13 ppm in its water. These treatments protect household plumbing, but phosphate is also a nutrient for algae. A feature that is topped up often with phosphate treated water keeps receiving that nutrient. Regular balancing and cleaning keep the growth in check before it coats stone or clogs the pump intake.
Topping up in dry years
Fountains lose water to evaporation and splash, especially outdoors on hot and windy days. Faster loss can come from a leak, a clogged line or a plumbing fault. An inspection of the circulation system is the way to tell which. Supply matters here too. New Hampshire law lets a town restrict outdoor lawn watering from private wells as well as public systems once the region is designated as under drought. Rochester's water code goes further at Level 3 and prohibits filling any swimming pool or container over 100 gallons. A feature that leaks during a stage like that may have to sit low, so finding the cause early keeps it running.
Shutting down before the first freeze
NOAA's 1991 to 2020 normals put the median first fall freeze on October 4 at the Durham station and on October 8 at the Greenland station near Portsmouth. The median freeze free period in Durham is 148 days. Water left in a fountain pump or its lines through a Seacoast winter can freeze and crack them. Outdoor features you do not plan to run through the cold should be drained and shut down before those dates. In spring they can be restarted once the risk has passed. The Durham station's median last spring freeze is May 8. A feature built into a pool is winterized as part of the pool closing.
Stains from metals in the water
Rust colored or dark stains on a fountain often trace back to the water rather than the surface. Portsmouth's 2025 Consumer Confidence Report recorded manganese up to 172 ppb and iron up to 470 ppb at some points, above secondary standards. Water like that can stain surfaces if it is not managed. NHDES notes that manganese also occurs naturally in private well water in New Hampshire. Stains are removed with methods suited to the material, since a heavy handed clean can damage natural stone. Balancing the water afterward helps keep the stains from returning. If your feature is filled from a well, a recent well test helps explain where the staining comes from and how to keep ahead of it.
Durham NH Water Feature Maintenance: Frequently Asked Questions
Where does Durham's public water come from and does it affect my pool?
The UNH/Durham Water System, run jointly by the University of New Hampshire and the Town's Public Works Water Division, draws on the Lamprey River and the Oyster River plus the Spruce Hole Well and the Lee Well, according to its 2025 Water Quality Report. Treatment includes an orthophosphate corrosion inhibitor. Phosphate protects household pipes but can feed algae once that water is in a warm pool, fountain or hot tub, so a steady sanitizer level matters.
When should I close my pool in Durham?
Close once the season is over and temperatures are clearly falling, but before the first hard freeze. NOAA's 1991 to 2020 normals at the Durham station put the median first fall freeze on October 4. The average high drops from 73.3 F in September to 60.6 F in October. Outdoor water features and any hot tub you will not use over winter should be shut down before then too.
Does Durham get hot enough in summer to affect my pool?
Yes. NOAA's 1991 to 2020 normals for the Durham station put the July average high at 82.5 F, with about 15.1 days a year at or above 90 F. Warm water uses up sanitizer faster and loses more to evaporation. Most pools in regular use do best with weekly service in summer. A level that keeps falling faster than the weather explains is worth a leak test.
Do you maintain commercial water features?
Yes. Commercial fountains in hotels, shopping malls and other public spaces are a core part of this service.
Can you look after a water feature that is part of my pool?
Yes. Waterfalls, spillways and other features built into a pool share its water and circulation, so they are maintained as part of looking after the pool.
