Grundfos UPA 15-160 In-Line Automatic Booster Pump for Home | Condominium | Apartment | Office | Old House (99331335)

The Problem:

Low Water Pressure for your Home/Condominium/Apartment/Office/Old House/Toilet



Situation:

In many residential buildings — especially multi-story homes, condominiums, and apartments — residents often experience weak water flow at showers, taps, or washing machines.



The issue usually happens when:

• The municipal (city) water supply pressure is too low.

• The water tank is positioned at a low level (e.g., ground floor tank supplying upper floors).

• Multiple residents use water at the same time, reducing available pressure.

• Long or narrow piping systems cause pressure loss over distance or height.



Effects:

• Shower water trickles weakly.

• Washing machines and dishwashers fill very slowly.

• Taps on upper floors barely flow, especially during peak hours.



The Solution: Grundfos UPA 15-160 Booster Pump



The Grundfos UPA 15-160 is a domestic booster pump specifically designed to increase water pressure in residential systems.

It:

• Boosts water pressure from your existing supply line (either direct from city supply or from a storage tank).

• Automatically turns on/off when it detects water flow (e.g., when you open a tap or shower).

• Operates quietly and efficiently for drinking water systems.



Example Scenarios:



1. Single-Family Home

• The homeowner notices that the second-floor shower has very low water pressure.

• The city supply line pressure is only around 1.0 bar — not enough for upstairs taps.

• Installing the Grundfos UPA 15-160 on the incoming cold-water line before it branches to the second floor boosts the pressure up to about 1.5–2.0 bar, giving a strong, comfortable shower flow.



Result:

Consistent, powerful water pressure at all taps and showers.



2. Condominium Unit

• A resident on the 8th floor complains that water trickles out during peak hours (morning/evening).

• The building’s main pressure is shared among many units, and higher floors get less pressure.

• The resident installs a Grundfos UPA 15-160 inside their unit’s main inlet pipe.

• When they open a tap or shower, the pump senses the flow and boosts the pressure instantly.



Result:

Normal, reliable water pressure even when neighbors are using water.



3. Apartment Building (Small Unit)

• An apartment unit located at the far end of the water line suffers from poor water flow.

• Because of pipe distance and multiple bends, the pressure drops significantly.

• A Grundfos UPA 15-160 is installed just before the tap/shower line.



Result:

The water pressure improves dramatically without needing major plumbing work.
