A Filtration System Matched to Your Pool, Not Just Fitted
Filtration is a system, not a single unit. The pump has to move the pool’s water through the filter at a rate the filter can actually handle: push water through too fast and debris passes with it; too slow and parts of the pool never properly get cleaned. We size the filter and pump together around the pool’s volume and a sensible turnover — the time taken for the full volume to pass through the filter — then lay out pipe runs with as few restrictions as possible, so the pump is not straining against its own plumbing.
The right setup depends on how the pool is used. A family pool in Karachi fights a constant load of dust, leaves and sunscreen through a long, hot season, and the hard water in many areas adds scale that slowly narrows pipes. Sand filtration suits most home pools and is simple to live with; cartridge and other media options trade different cleaning effort against finer filtration. The plant-room layout, drainage for backwash water and access for servicing are all planned at this stage, not improvised afterwards.
What’s Included
- Volume & turnover calculation — filter and pump sized together against your pool’s actual water volume.
- Media filter installation — sand or chosen media correctly filled, multiport valve fitted and tested.
- Pump pairing & fitting — a pump matched to the filter’s flow range, mounted for quiet, serviceable running.
- Efficient pipe runs — suction and return lines laid out to reduce strain, air locks and pressure loss.
- Backwash & waste plumbing — a proper waste line so backwashing is quick and does not flood the plant area.
- Pressure testing & handover — system run under pressure, leaks checked, and the backwash routine explained to you.
An undersized or mismatched system does not fail loudly — it fails as water that is never quite clear, a pump that burns out early, and chemicals that seem to disappear. Getting the sizing and plumbing right once costs less than years of fighting a system that was never matched to the pool.
Choosing the Right Filter for Your Pool
Every filter does the same job — trapping dirt as water circulates — but they work differently. Sand filters push water through a bed of special sand and are simple and forgiving, which is why they suit most home pools. Cartridge filters use pleated elements that catch finer particles and need no backwashing, just periodic rinsing and replacement. DE (diatomaceous earth) filters give the finest filtration but need the most attention. Whichever type, the filter must be sized to your pool’s volume and pump so the water turns over at a healthy rate.
You can see the filter types we supply on our pool filters page.
How often should I backwash a sand filter?
Backwash when the pressure gauge rises noticeably above its clean reading, or roughly every few weeks in the swimming season — it depends on use and dust. Backwashing too often actually reduces filtration, because a slightly loaded sand bed filters finer than a freshly cleaned one.
What size filter does my pool need?
Sizing follows your pool’s volume and the pump’s flow rate — the filter must handle at least the flow the pump delivers, and the pair should turn over the full pool volume in a reasonable time each day. We calculate this from your pool’s dimensions before recommending a model.
How do I know if my filter is failing?
Warning signs include water that stays cloudy despite correct chemicals, dirt returning to the pool through the inlets, sand appearing on the pool floor, or pressure that will not settle after backwashing. Any of these is worth an inspection before the pump is damaged.
