Low Water Pressure in Your Apartment? How to Choose the Right Booster Pump

Weak showers, slow-filling buckets and geysers that won't switch on are classic symptoms of low water pressure. It's one of the most common complaints in Bangalore apartments, duplexes and villas — and it's easy to fix with the right pressure booster pump.

Why is water pressure low?

• Gravity supply: overhead tanks create only ~0.1 bar per metre of height. Top floors directly below the tank get very little pressure.
• Long pipe runs and many bends reduce flow.
• Multiple outlets open at the same time.
• Rain showers, solar heaters and pressurised geysers need more pressure than gravity provides.

Types of pressure pumps

How to choose

1. Count outlets likely to run together (showers, taps, washing machine).
2. Check the source — overhead tank, sump or direct line.
3. Measure height difference between tank and highest outlet.
4. Look for features: variable speed, dry-run protection, low noise, auto on/off.

Why we often recommend Grundfos SCALA2

It's a compact all-in-one unit with an integrated controller that keeps pressure constant whether one tap or five are open, runs under 47 dB, and protects itself against dry running — ideal for homes.

Installation tips

• Install close to the tank outlet with a non-return valve.
• Use a bypass so water still flows during maintenance.
• Ensure ventilation and protection from rain.
• Get a dedicated electrical point with earthing.
