The “Power Shower” Guide

You turn on the shower expecting a refreshing blast of water, but instead, you get a weak, sad drizzle. Sound familiar?

If you live on the top floors of a high-rise apartment in Dhaka or Chittagong, low water pressure is a daily frustration. Most people blame the WASA supply, but the real issue is often your building’s plumbing physics—specifically, the “Gravity-Fed” system.

In Bangladesh, water tanks are usually on the roof. If you live on the 8th floor of a 10-story building, there isn’t enough vertical distance (“head”) for gravity to build up strong pressure.

You might not be able to change your building’s plumbing, but you can choose the right fixtures. Here is how to get a spa-like shower even with low pressure, using Harrington solutions.

1. Stop Buying “Restictive” Mixers

Many imported faucets are designed for Europe, where water pressure is pumped at high bars. These faucets have narrow internal channels that choke the water flow.

• The Problem: When you put a “High Pressure” mixer in a “Low Pressure” Dhaka apartment, the flow drops to zero.
• The Harrington Solution: Our Single-Lever Shower Mixers are designed with High-Flow Ceramic Cartridges. These have wider internal waterways that allow maximum water to pass through, even if the pressure from the tank is weak.

2. Rain Shower vs. Hand Shower: The Critical Choice

We all love the look of a giant 12-inch rain shower head. But be careful.

• The Physics: A giant head spreads the water over a large surface. If your pressure is low, the water will just dribble out.
• The Fix: If you don’t use a pressure pump, stick to a Harrington Hand Shower or a smaller (6-8 inch) overhead shower. Our hand showers are engineered with focused nozzles that artificially boost the spray force, making the water feel stronger than it actually is.

3. Check the “Diverter” Quality

Have you ever used a concealed mixer where you pull the knob to switch to the shower, but it keeps falling back down? That’s a sign of a weak diverter struggling with pressure.

• Harrington’s Edge: We use Locking Diverters in our concealed systems. Whether the pressure is high or low, once you switch the water flow to the shower, it stays there until you turn it off.

4. The “Hidden” Clog (Aerators & Filters)

Sometimes, the pressure is fine, but the sediment has blocked your flow.

• Sand & Iron: New buildings in Bangladesh often have sand in the pipes. Old buildings have iron rust.
• Maintenance Tip: As mentioned in our cleaning guide, Harrington shower heads come with silicone nozzles. If the flow gets weak, just rub the nozzles with your thumb while the water is running. This dislodges the sediment instantly and restores full pressure.

5. When to Buy a Pressure Pump?

If you want a massive “Monsoon” style rain shower (12 inches+), gravity alone won’t work.

• Recommendation: We honestly recommend installing a small 0.5 HP Pressure Pump for your bathroom line.
• The Result: Pair that pump with a Harrington Thermostatic Mixer, and you will have the best shower experience in the city—consistent heat and powerful force.

Summary: Don’t Suffer with a Dribble

Low pressure doesn’t mean you have to settle for a bad shower. It just means you need smarter hardware.

• For Low Pressure: Choose Harrington Single-Lever Mixers + Hand Showers.
• For High Pressure (Pump): Choose Harrington Rain Showers + Concealed Mixers.
