Durham NH Pool Maintenance
Puddle Pool Services provides pool maintenance in Durham, New Hampshire and the Seacoast towns around Portsmouth, Dover and Exeter, caring for the pump, filter, heater, valves and plumbing as well as the water. Each visit checks filter pressure, the pump and its baskets, visible plumbing, the liner or surface, covers and fittings, then balances the chemistry for your water source. An E-Report with readings and photos follows every visit.

The equipment behind clear water
Clean water and a healthy pool are not the same thing. Cleaning handles the water and the surfaces, while maintenance also covers the pump, filter, heater, valves and plumbing that keep them that way. A pool can look perfect while a pump bearing wears or a filter loads up, and maintenance exists to catch that before it turns into a replacement. Each visit checks the filter and its pressure, the pump and its baskets and the visible plumbing and valves. It also covers the condition of the liner or surface, the covers and the fittings. If you own a hot tub as well, it can sit on the same plan, since its small hot volume needs the same care for chemistry, filters and equipment and usually needs it more often than a pool.
Salem water changes with the season
Fill water is the starting point for every balance, and in Salem it changes during the year. The Town's Utilities page says Canobie Lake is the primary source from May through October and Arlington Pond takes over in the colder months. Since June 2020 Salem has also received treated Lake Massabesic water from Manchester Water Works through the Southern NH Regional Water Project. Salem's 2025 report rates the water slightly hard at 57.6 mg/L, and it shows sodium of 61.9 mg/L in the Canobie Lake water against 34.8 mg/L from Arlington Pond. The Town also runs a carbon dioxide system to raise alkalinity for corrosion control. A pool topped up across the switchover can see its numbers move even when nothing else has changed.
Soft water and disinfectant switches
Some supplies in the territory sit at the soft end. Derry's public water comes from Manchester Water Works, whose 2025 report lists calcium of about 4.2 ppm at its Lake Massabesic plant and 6.65 ppm at its Merrimack River plant, which makes the water very soft. Fill water that soft will need its calcium raised to reach a typical pool calcium hardness. Manchester Water Works normally disinfects with chloramine but periodically switches to free chlorine, and the Town of Derry posts a notice when it does, which changes how fresh fill water responds to pool chlorine. Exeter's 2026 water report lists a pH of 8.3, on the high side for fill water. Your technician factors each of these in when balancing a pool that has just been topped up.
When equipment starts to drift
Most equipment problems announce themselves slowly. Water that takes longer to clear than it used to, a pump that sounds different, pressure readings that wander from their normal range or chemistry that will not hold are all worth mentioning, since early attention costs less. Water balance plays into this as well. Water low in alkalinity or pH turns corrosive to metal parts, heaters and fittings, and water running high tends to scale. Pump run time is a frequent question with no single answer. The pump should run long enough to turn over the pool's full volume, which depends on the size of the pool and the capacity of the pump. Too little running is the usual reason water will not stay clear, and your technician can tell you what fits your setup.
A short season with long shoulders
The swimming season here is compact. NOAA's 1991 to 2020 normals give the Durham station a median freeze free period of 148 days and the W Hampstead station used for the Derry area 162 days. The Lawrence, Massachusetts station used for Salem, an urban river valley site, reaches 198 days, though the W Hampstead figures point to a shorter season away from the Merrimack valley. Maintenance is usually heavier through the swimming months and lighter outside them, and some equipment work is easier when the pool is not in use. A pool sitting idle through the shoulder months still needs either regular care or a proper closing, because untreated standing water and equipment left without attention are where trouble starts quietly.
Durham NH Pool Maintenance: Frequently Asked Questions
Why does Salem tap water change through the year?
Salem's Utilities page says Canobie Lake is the primary source from May through October and Arlington Pond in the colder months, with treated Lake Massabesic water from Manchester Water Works also arriving through the Southern NH Regional Water Project. The Town's 2025 water report lists sodium of 61.9 mg/L in Canobie Lake water and 34.8 mg/L in Arlington Pond water. A pool or spa topped up across the switch can see its balance shift, which regular testing picks up.
Can a water hauler fill a pool with Rochester city water?
Only through the City's process. Rochester's water code says DPW does not use its equipment to fill private pools, private companies need written DPW authority to use system water and pool water haulers must use the City's designated bulk water stations. Drawing water from a hydrant counts as tampering. Contact DPW before arranging a large fill for a home or commercial pool.
Which Durham NH neighborhoods do you cover?
We look after pools across Durham NH, including Downtown Durham, University of New Hampshire, Madbury Road & Faculty Neighborhoods, Lee, Madbury and Newmarket. The full list of areas is on our Durham NH page. If you do not see yours, get in touch and we will confirm.
What is the difference between maintenance and cleaning?
Cleaning is about the water and the surfaces. Maintenance also covers the system that keeps them that way: the pump, filter, heater, valves and plumbing. A pool can look clean while the equipment behind it is failing, which is the situation regular maintenance is meant to catch.
How do I know whether my equipment needs attention?
The signs are usually gradual: the pool takes longer to clear than it used to, the pump sounds different, pressure readings drift from their normal range or the water is harder to keep balanced. Any of those is worth mentioning, because equipment problems are cheaper to address early.
