Pool pump and filter replacement, repair and servicing for villas, rentals and community pools across the Costa del Sol. Variable-speed pumps, sand and glass-media filters, registered electrician for the boletin.
Variable-speed pumpsSand and glass filtersHard-water suitedThree-year warranty
A pool pump that has not been serviced in three summers usually fails in early July, the worst possible week to find a free engineer on the coast. The pool turns green inside forty-eight hours without circulation. Filter sand caked with calcium scale stops sieving particles long before the gauge shows a problem. Most of the pump and filter calls we attend in summer trace back to neglect or to the wrong-size kit fitted by the original builder. We replace, repair and service pool pumps and filtration systems for villas, rentals and small community pools across the Costa del Sol from Nerja to Gibraltar.
Variable-speed vs single-speed pumps
Single-speed pumps run at one fixed speed: full power or off. Variable-speed (inverter) pumps run at the speed the pool actually needs, which is usually around forty to fifty percent for routine circulation and one hundred percent for backwashing the filter. Running cost on a variable-speed pump is typically a third of a single-speed unit on the same pool, because most of the day the pump only draws a fraction of the wattage. Spanish electricity tariffs make the saving worth the higher upfront cost within two seasons. New installs and replacements default to variable-speed unless the owner specifically asks for single-speed.
Variable-speed: one third the running cost of single-speed
Single-speed: cheaper to buy, replaced as direct swap on existing installs
Both run from the existing 230V supply with appropriate RCD
Variable-speed needs a programmable timer or pool controller
Sand, glass and cartridge filters
Three filter media cover almost every Costa del Sol pool. Sand is the default: cheap to fit, easy to backwash and serviceable for ten years before the sand needs replacing. Recycled glass media replaces sand on a like-for-like fitting, lasts longer, traps finer particles and resists biofilm better. Cartridge filters use a paper-element filter cleaned by hose, which suits smaller pools and saves the water lost during backwashing. We pick the filter type by pool volume, the local water hardness and how often the pool will be used. Hard mains water on the coast scales filter media faster than the same kit in northern Europe, which is why we recommend a media check every three years.
Sizing the system to the pool
A correctly sized system turns over the pool volume in four to six hours during the swimming season and eight to ten hours through winter. A small private pool of 30 to 40 cubic metres needs a 0.75 to 1 hp pump and a 600 mm sand filter. A standard villa pool of 50 to 70 cubic metres needs 1 to 1.5 hp and a 750 mm filter. A larger pool of 80 to 100 cubic metres or a small community pool needs 1.5 to 2 hp and an 800 to 900 mm filter, sometimes split across two pump-and-filter sets. Undersized kit struggles to clear the pool. Oversized kit wastes electricity and can damage the filter media.
Electrical and bonding rules
Pool pumps need a dedicated circuit with an RCD on the consumer unit and an equipotential bond between the metal parts of the pool, the pump and the earth bar. Spanish wiring norms require IP-rated outdoor sockets and switchgear, with the pump enclosure positioned a minimum distance from the pool edge. A registered electrician issues the boletin, which is the certificate the property owner needs for insurance and resale. We replace the bonding strap and check the earth path on every pump replacement, since older installs from the early 2000s often have a corroded or missing bond.
How the work runs
From first call to commissioned system
Step 1
Site survey
An engineer visits the property to measure the pool volume, check the existing pump and filter, test the bonding and the RCD, and identify whether a pump or full system replacement is the right answer. Survey appointments are free.
Step 2
Quote and equipment pick
We send a written quote with the recommended pump and filter, the rationale for variable or single-speed, all materials, the boletin fee where the circuit needs upgrading and the labour figure. No deposit until you accept it.
Step 3
Installation
Most pump replacements run as a half-day job. A full system swap with new filter media, valves and pipework takes one to two days. We empty the filter, fit the new pump on a level base, run the pipework with isolation valves either side and recommission the pool.
Step 4
Commissioning
We programme the variable-speed pump for the season, set the filter cycle, prime the system and check pressure across the filter. The owner gets a one-page operating sheet with backwash and timer settings.
Step 5
Warranty and aftercare
Three-year EnviroCare parts and labour warranty starts the day the system is signed off. Service history goes on file for any future callout. Send a WhatsApp to +34 670 409 759 to book a survey.
Why EnviroCare
Local experience that matters on the job
Trading since 1996
Close to thirty years installing and servicing pool equipment for British and European homeowners across the coast from Nerja to Gibraltar.
Hard-water experience
Costa del Sol mains water is hard. We pick filter media, pump seals and pipework that hold up in real local conditions, not just on the manufacturer brochure.
Registered electrician for the boletin
Pool circuit work needs a boletin from a registered electrician. Our team handles the certification as part of the install.
Three-year parts and labour
Every new install carries a three-year EnviroCare warranty on parts and labour, on top of the manufacturer warranty on the pump and filter.
How long should a pool pump last on the Costa del Sol?
A correctly sized pump from a quality manufacturer runs eight to twelve years on a residential pool with annual servicing. Bearings, mechanical seals and impellers are the parts that fail first under hard-water conditions. The motor itself usually outlasts the wet end. Replacement seal kits keep most pumps going for the full lifespan without a full unit swap.
Is a variable-speed pump worth the extra cost?
Yes for almost every pool that runs more than three months of the year. Running cost typically drops to a third of a single-speed pump because the pump only runs at full speed during backwashing. Payback is usually within two seasons. The control gives finer cycling for solar covers, cleaning robots and pool heat pumps.
How often should the filter be backwashed?
When the pressure gauge reads roughly 0.3 bar above the clean baseline. In summer that is usually once a week. In winter, once every two to three weeks. Backwashing more often than the gauge calls for wastes water and chlorine and shortens the filter media life. We set the baseline at commissioning and mark the gauge at the right pressure for clarity.
Can a failing pool pump damage the filter or the heater?
Yes. A pump losing prime or running on a worn impeller drops the flow rate through the system. Filter media starts to channel rather than sieve. A pool heat pump in line will trip on flow-switch error and refuse to fire. The whole system runs on the pump, which is why we recommend an annual pre-season service rather than waiting for failure.
What about saltwater chlorination cells?
Chlorination cells run from the same pump-and-filter circuit and need the right flow rate to work properly. A failing pump kills the salt cell as well. We service the cell alongside the pump and recalibrate the salt level at the annual visit. Cell life on the Costa del Sol is typically four to six years on a residential pool.
Do you service pumps from any brand?
Yes. We service equipment regardless of who installed it: AstralPool, Hayward, Pentair, Bestway, Espa, Saci and the supermarket-brand pumps fitted by the original developer. Parts for the major brands are stocked locally on the coast. Send a WhatsApp to +34 670 409 759 to book a survey if a pump has stopped or the pool is starting to lose clarity.
