Low water pressure in tank? Install this special pipe for strong flow
- •Install a 1 to 1.5-inch CPVC or UPVC pipe at the tank outlet and gradually reduce the size using fitting reducers.
- •Avoid iron pipes as they accumulate rust and dirt over time, which obstructs water speed and reduces pressure.
- •Keep pipe bends to a minimum and use 45-degree elbows or longer bends instead of excessive 90-degree elbows to maintain good flow.
- •Install an air vent pipe about 1.5 feet above the tank level to prevent air locks that can stop the water flow.
- •Keep the tank outlet about 2 to 2.5 inches above the bottom to prevent accumulated sediment and waste from entering the pipeline.

To increase water pressure, install a 1 to 1.5-inch CPVC or UPVC pipe at the tank outlet instead of using iron pipes which accumulate rust and dirt over time. Gradually reduce the pipe size using fittings as it leads to individual rooms, such as using a 3/4-inch pipe for the bathroom or kitchen.
It is best to use good quality CPVC or UPVC pipes rather than cast iron. Start with a 1 to 1.5-inch main supply pipe at the tank outlet, and gradually narrow the width down to 1.25 inches, 1 inch, or 3/4 inch using reducers as the pipeline extends toward lower floors.
Excessive bends and 90-degree elbows can obstruct water flow and reduce pressure, so it is helpful to use 45-degree elbows or longer bends instead. Additionally, installing an air vent pipe about 1.5 feet above the tank level prevents air locks from stopping the water flow.
