What it involves

The filtration system is the heart of the pool: the pump moves the water, the filter traps the dirt and the multiport valve decides whether you filter, backwash, rinse or drain. If a part fails or is the wrong size, the water turns cloudy, the electricity bill goes up or the pump ends up burning out in the middle of summer. We take care of the whole system, from a pump that has stopped starting to a brand-new plant room.

We calculate the flow rate from the pool volume, the length of pipework and the filter, and from there we choose the pump, ideally a variable-speed one, the sand or glass media filter, the valve and the electrical control panel with its timer. We build underground pump housings and plant rooms with ventilation and drainage, swap old lights for LED lighting, set up robotic pool cleaners and, if you like, automate filtration and lights so you can control them from your phone.

We work for villas, detached houses, communities of owners and holiday accommodation, on new systems as well as installations with many years behind them that need sorting out. If you also want to heat the water or switch to a salt water system, we leave the circuit ready and handle it through those dedicated services.

Pumps, filters and filtration: jobs we do

These are the jobs we are asked for most around the province. If yours looks like one of them, call us and we will tell you how we would handle it.

Complete pool filtration system installation

When the old system is no longer worth repairing, or a pool has a makeshift installation, we fit a complete filtration system: pump with pre-filter, filter, multiport valve, manifolds, shut-off valves and an electrical panel with protection devices and a timer. First we measure the pool volume, count the skimmers, main drain and return jets and check the pipe diameter, because the real flow rate depends on it. We label every valve with the line it opens, bleed the circuit, programme the filtration and show you how to backwash and rinse the filter.

Pool pump won't start or is noisy

A pump that hums without turning usually has a worn-out capacitor or a shaft that has seized over the winter; if it squeals or vibrates, it's the bearings; if it drips under the motor, it's the mechanical seal. We diagnose the fault in the plant room itself and tell you clearly whether it's worth repairing or replacing. If it needs replacing, we choose a pump with the right flow rate for your filter and pipework, not just a more powerful one, and leave it firmly secured, aligned with the pipes and primed.

Variable-speed pool pump to cut electricity use

A variable-speed pump filters for most of the day at low revs and only speeds up for backwashing, the pool cleaner or a water feature. Because consumption falls sharply at lower speed, the saving over a single-speed pump shows on your bill, and it's much quieter too. We install it with time-band programming: more flow during swimming hours and the hottest part of the day, a low setting at night and short boosts so the skimmer picks up leaves and dust.

Sand filter change or switch to glass filter media

Over time the sand clogs with limescale and grease and forms channels where water passes through unfiltered, so the pool turns cloudy even when the chlorine is right. We empty the filter, check the laterals at the bottom, which often turn out to be broken, and refill it with fresh silica sand or glass media, which traps finer particles and usually needs shorter backwashes. If the filter is cracked, has a damaged lid or is too small for your pump, we replace it with one of the right size.

Replacing pool lights with LED lighting

Old halogen lights use a lot of power, blow often and heat up the niche. We replace them with white or colour LED lights, usually reusing the same niche and wiring, with a suitable safety transformer in the panel. We also add lights to pools that didn't have any, cutting the niche and the conduit to the junction box, and link them to the timer or your phone so the pool lights up by itself at dusk.

More jobs in this service

  • Multiport valve leaking water to waste

    If water comes out of the filter's waste outlet even with the handle set to filter, the spider gasket or the valve's internal rotor is worn. We replace them or fit a whole new valve, and check that the handle locks properly in each position.

  • Pool filter pressure gauge rises soon after backwashing

    If the filter pressure shoots up a few days after backwashing, the media is clogged with limescale, too much dirt is getting in or the filter is too small for the pump. We measure pressures, check the media and pre-filter and fix the underlying cause.

  • Flooded underground pool pump housing

    Underground pump housings next to the pool collect rainwater and backwash water, and a heavy storm can leave the pump submerged. We fit a sump pump with a float switch, improve drainage and ventilation, raise the equipment on a plinth and seal the lid.

  • Pool plant room refit and tidy-up

    Many plant rooms are a tangle of pipes added over the years, with no shut-off valves or room to work. We rebuild the manifolds in pressure-rated PVC, fit a valve on each line and leave space for future equipment, plus a diagram of what each valve opens.

  • Pool pump control panel keeps tripping

    If the RCD trips when the pump starts or with the damp at night, we check the motor insulation, contactor, protection devices and connections. We fit new sealed panels with RCD, circuit breaker, motor protection and timer, raised off the floor and away from splashes.

  • Pool pump timer and filtration hours

    We set the timer to filter more in summer and less in winter, splitting the hours into several slots and making use of the cheapest electricity tariff, or the sunny hours if you have solar panels. We replace broken mechanical timers with digital ones.

  • Robotic pool cleaner

    We help you choose a robotic cleaner to suit the shape of your pool, whether it has built-in steps or benches and whether you want it to climb the walls and clean the waterline. We set it up, show you how to clean its filter and repair brushes, tracks, float and cable.

  • Control your pool pump and lights from your phone

    With a wifi controller in the panel you can switch the pump, lights and other equipment on and off and change their schedules from your phone, and see if something has stopped working. It's very handy if you live abroad and the house is shut for long spells.

  • Air bubbles from the return jets: pool pump drawing air

    If you see bubbles coming out of the jets or the pre-filter is half empty, the pump is sucking in air: a pre-filter lid with a dried-out seal, a loose fitting on the suction side or the water level below the skimmer. We find where the air is getting in and seal it before the pump runs dry.

  • Noisy pool pump disturbing the neighbours at night

    On urbanisations with plots close together, a pump vibrating in the early hours can be heard all down the street. We fit anti-vibration mounts and flexible joints, soundproof the housing without cutting its ventilation and, with variable speed, programme a very low setting for the night.

  • Pump for pool waterfalls, jets and water cannons

    Waterfalls, water curtains and cannons need their own flow and shouldn't steal it from the filtration. We fit an auxiliary pump with its own line, valve and schedule, or use a variable-speed pump that speeds up only when you turn the feature on.

  • Oversized pool pump overloading the filter

    It's a common mistake: fitting a bigger pump so it cleans better. If the flow exceeds what the filter can take, the sand gets churned up, water passes through unfiltered and the pipes get noisy. We measure and match pump, filter and pipe sizes so they work in balance.

  • Pool equipment corroded by salt air on the seafront

    Close to the sea, salty air attacks screws, terminals, motor casings and electrical panels. We replace rusted parts with stainless steel or plastic, fit sealed panels, protect the connections and improve ventilation so the salty damp doesn't linger inside the housing.

  • Balancing suction from skimmers, main drain and pool cleaner

    If only the skimmer nearest the housing is pulling water and the rest barely move any, the circuit is unbalanced. We adjust the valves on each line, check diameters and, if needed, rebuild the suction manifold so the whole surface of the pool is turned over.

What you get with us

  • Equipment calculated, not guessed

    Pump, filter and pipework are sized together from the volume and the actual circuit. That way you filter properly, use less power and the equipment lasts longer.

  • Fixed written quote

    Before we change anything we itemise each piece of equipment, the installation materials and the labour, so there are no surprises when the job is done.

  • We explain it in your language

    English, Spanish and German spoken: we walk you through the panel, backwashing and the filtration schedule so you can run your system without relying on anyone.

  • Clean, safe installations

    Sealed panels with protection devices, equipment on plinths, accessible valves and tidy wiring. We carry public liability insurance and leave the housing better than we found it.

How we do it, step by step

  1. Inspecting the equipment and circuit

    We look at the pump, filter, valve, panel and pipework, measure pressures and flow, and note the pool volume and the number of skimmers and return jets.

  2. Proposal with calculations

    We explain what's worth repairing and what to replace, with the flow rate required and the equipment proposed, and send you the detailed proposal before we start.

  3. Installation and connections

    We mount the equipment on plinths, rebuild manifolds and valves if needed, connect the electrical panel and check there are no drips or air leaks.

  4. Start-up and programming

    We prime the pump, bleed the filter, set speeds and schedules for the season and programme the lights, pool cleaner and phone control.

  5. Walkthrough and handover

    We show you how to backwash and rinse the filter, read the pressure gauge and empty the pre-filter basket, and leave you a diagram of the installation.

Pumps, filters and filtration in Alicante province

In the province of Alicante a filtration system works long hours: long swimming seasons, water that gets very warm in August and a sun that sets off algae as soon as filtration falls short. Add to that the hard mains water, which leaves limescale in the filter sand, the pre-filter and the seals, so filters clog sooner and need fresh media more often than in soft-water areas. And in a drought every backwash counts, so fine-tuning pressures and choosing the right media saves real water.

The setting shapes the installation too. On the seafront in Benidorm, Calpe or Torrevieja, salt air corrodes panels and motors; the 1970s and 1980s villas of l'Alacantí are full of underground pump housings that flood with every gota fría; on urbanisations with tightly packed plots, the pump's night-time noise ends in complaints; and in the homes of European residents who spend months away, being able to check and control the system from a phone saves nasty surprises on their return.

Where we do it

Swimming pools in Elche and Santa Pola

The Camp d'Elx, with its houses among pomegranate orchards and palm trees, and the coast from Arenales del Sol to Santa Pola call for very different pools. We build in the countryside, renovate villas and look after the water for people who only spend part of the year here.

Frequently asked questions

What people ask us most about pumps, filters and filtration.

Pumps, filters and filtration: your questions

How many hours a day should the pool pump run?

A handy rule of thumb is to filter for as many hours as half the water temperature: with the water at twenty-eight degrees, about fourteen hours. In winter very little time is enough. With a variable-speed pump you can filter almost all day at low speed and use less power. It's best to split the hours into several slots and have them partly coincide with the sunniest and busiest swimming hours.

Sand or glass filter media: which is better?

Silica sand is cheaper and works well if it's renewed in time. Glass media traps finer particles, clogs less with limescale and usually needs shorter backwashes, which is welcome during water restrictions. It goes into the same sand filter, so the switch is simple. For heavily used pools or very hard water we usually recommend glass.

Is it worth replacing a working pump with a variable-speed one?

If your pump is old and filters many hours a year, usually yes: consumption drops sharply when it runs at low revs, the noise almost disappears and the filter works better with a gentle flow. If the pool is little used or the pump is recent, it may not pay off yet. We do the maths with your filtration hours and current power rating so you can decide on the numbers.

How often should the sand in a pool filter be changed?

As a rough guide, every few seasons, but in the province of Alicante, with hard water, long filtration hours and pools used from spring to autumn, it clogs sooner. The signs are clear: cloudy water even with the chlorine right, pressure rising soon after backwashing, or sand coming out of the jets, which usually points to a broken lateral at the bottom of the filter.

Can the pool pump and filter be moved elsewhere on the plot?

Yes. Sometimes the housing is in a spot that floods, bothers the neighbours or gets in the way of a garden makeover. We move the equipment to a new housing or plant room, extending the suction and return pipes at the right diameter so no flow is lost and making sure the pump sits at a height where it can prime properly.
