The Challenge: Poor Water Pressure Throughout the Villa
The villa owner contacted Agua Therm after experiencing persistent poor water pressure throughout the property. The existing plant room was outdated and inadequate for the villa's demands, resulting in frustratingly weak showers, slow-filling baths, and inconsistent water flow to upper floors. Key issues included:
- Poor water pressure causing weak showers and inadequate flow
- Complete strip-out of outdated and failing equipment required
- Energy-efficient variable speed pump technology needed for pressure boosting
- Professional water treatment and softening system to protect new equipment
- Future-proof installation with easy maintenance access

"This Benahavís project was a complete transformation. The owner was suffering from really poor water pressure throughout the villa - weak showers, slow-filling baths, the lot. The original plant room had outdated fixed-speed equipment that simply couldn't deliver the pressure needed. By stripping everything out and rebuilding with ESPA Speedrive V2 variable speed technology, we've completely solved the pressure problems while also dramatically reducing energy consumption. The dual pump configuration with intelligent alternation means this system will serve the property for decades with minimal maintenance."
Rob Greeves
HVAC Director, Agua Therm
"From an electrical standpoint, this plant room rebuild showcases best practice. The ESPA Speedrive V2 units eliminate the massive current surges you get with traditional pump starts - that's gentler on the villa's electrical infrastructure and reduces the risk of trips. We've integrated everything with proper MCB protection and clearly labelled distribution, making future maintenance straightforward. The water softener protects not just the pumps but all the villa's plumbing and appliances from limescale damage. Combined with the expansion vessels for pressure stability, this is a complete water management system built to professional standards."
