Pool servicing in Heritage Springs.

The first generation of Pakenham estate pools.

Heritage Springs was the early-2000s wave of Pakenham master-planned estate builds — quarter-acre blocks, 8×4 family pools, single-speed Onga or Davey pumps, sand filters, basic salt chlorinators. Twenty years on, the shells are doing fine but the equipment package is well past its design life. Most of our one-off work in Heritage Springs is replacement, not servicing.

Equipment replacement pays for itself.

The single biggest energy win on an old Heritage Springs pool is swapping a single-speed pump for a variable-speed unit. A 1.5 kW single-speed running 8 h/day through summer is roughly $400 / year on a Pakenham power bill. A modern VS pump doing the same turnover is closer to $90. The pump itself costs $1,200–$1,800 fitted — payback in 3 summers, then it’s pure savings. Salt cells and sand filters are usually next.

Stabiliser is the silent killer.

Cyanuric acid (CYA, the “sunscreen” for chlorine) has almost certainly drifted off-spec on a 20-year-old pool that hasn’t been regularly serviced. Low CYA and the sun destroys your chlorine in hours. High CYA and chlorine gets locked up and stops sanitising. We test CYA on every first visit to Heritage Springs — about half the time it’s wildly outside the 30–80 ppm safe band.
