Why get your pool diagnosed?

A diagnostic is a full state-of-play: water quality, condition of the pool shell, skimmers, plant room, pump and filter. The professional looks at what's working, what's starting to wear, and what can safely last another season.

Think of it like your car's MOT: most points come back green, but the ones that turn amber save you a big bill in the middle of August.

Two ideal moments:

• March / April, just before the spring start-up, to begin the season on solid footing.
• October, before winterising, to lock things in good condition.

In our region, limescale, prolonged heat and Mediterranean pollen speed up wear. An annual check is enough to avoid surprises.

• The water balance (pH, chlorine, alkalinity, hardness, stabiliser).
• The pump and filtration: pressure, flow, noises, seals.
• The skimmers, return jets, vacuum points and the waterline.
• The condition of the liner or finish, coping stones and fixings.
• The electrical panel and the controller, often overlooked.

The professional walks you through each point out loud, in plain language.

At the end, you receive a written report with photos and recommendations ranked by priority. No obligation: you decide what to fix, when, and with whom.

If you choose Pool-Hero for the follow-up work, the cost of the diagnostic is deducted from the quote for any intervention within 30 days.

A water quality check is quick and focused on the chemistry. A diagnostic looks at the whole ecosystem: water + equipment + pool shell. If you're unsure, start with the diagnostic — you'll get the full picture, and the water check is included.
