Why Riyadh Pools Demand Constant Maintenance
Maintaining a swimming pool correctly is a technical necessity for any homeowner in Saudi Arabia. The constant airborne dust and seasonal sandstorms place a massive, continuous mechanical load on your villa’s filtration basin.
Failure to perform a weekly backwash protocol will destroy high-spec Italian motors commonly used in luxury properties. When the filter clogs, the internal pressure skyrockets, leading to fractured laterals, cloudy water, and ultimately, severe foundation seepage.
- Prevents high-pressure pipe bursts
- Eliminates green algae growth
- Saves thousands in pump replacements
- Keeps water safe for children
Step-by-Step
The Backwash Protocol
System Power Down
Always turn off your pool pump before moving the multiport valve handle. Moving it while running breaks the internal spider gasket.
Backwash Mode
Push the handle down, turn it to “Backwash”, and turn the pump on. Run for 2-3 minutes until the sight glass water runs clear.
The Rinse Phase
Turn the pump off, switch to “Rinse”, and run for 45 seconds. This resets the sand bed so dirty water doesn’t blow into the pool.
Return to Filter
Turn the pump off again, rotate back to “Filter”, and turn the system on. Check the pressure gauge—it should read 10-15 PSI.
Is Your Pressure Gauge Still High?
If you backwash your filter and the pressure gauge immediately jumps back to 20+ PSI, or your water remains cloudy, your sand is dead. In Riyadh, heavy dust and sunscreen oils cause filter sand to petrify into solid rock. You need a complete Filter Sand Replacement immediately to save your pump.

Filter Technologies
Sand Filters
The most common and robust filter for Riyadh villas. Uses silica sand or glass media to trap dust.
- Maintenance: Weekly Backwash.
- Lifespan: Sand must be changed every 3-5 years.
Cartridge Filters
Uses pleated fabric to catch finer dirt. Great for indoor pools but struggles with heavy desert sandstorms.
- Maintenance: Remove and hose down monthly.
- Cleaning: Requires soaking in acid solutions.
D.E. Filters
Diatomaceous Earth filters provide microscopic clarity, catching particles as small as 2 microns.
- Maintenance: Requires adding new D.E. powder after backwashing.
- Complexity: Highly technical to maintain.
Glass Media Upgrade
Replacing traditional sand with crushed, recycled glass media for superior water clarity.
- Efficiency: Catches much finer dust.
- Lifespan: Lasts up to 10 years without calcifying.
Real Results
Client Experiences
“My pool was constantly green despite adding chlorine. Mehwar’s engineers opened my filter and showed me the sand had turned into solid rock. After they replaced it with glass media, the water is flawless.”
“I broke my multiport valve because I didn’t know I had to turn the pump off before moving it. This guide is spot on. I now have Mehwar handle my weekly VIP maintenance.”
“After a massive sandstorm in Riyadh, my pool was brown. Their emergency team came the next day, backwashed the system, and shocked the pool back to crystal clear.”
