Installing a water heater at home is a very important step and is an indispensable appliance that provides hot water at any time. So what should you do if you find that the water flow from the showerhead is low during use?

What to do if the water flow from the showerhead is low

It is possible that the spray holes are clogged with impurities. After long-term use, scale may form on the nozzle, especially for non-metal nozzles. More scale not only reduces the flow but also misdirects the small holes, making the shower uncomfortable. At this time, you can add some descaling agent to water to create a solution, place it in a deep container, detach the showerhead from the water pipe, and immerse the entire showerhead in the container so that the water covers it. After soaking for over an hour, remove it, reattach it to the water pipe, and rinse thoroughly with water before use.

Do not use needles or wires to poke through the small holes, as this will not be effective and may damage the nozzle. For metal spray nozzles, use this method with caution. If using this method, the soaking time should be short.

The reasons for low water flow from the showerhead are as follows:

1. The showerhead may have adjustable settings. You can adjust the flow rate and spray mode using a knob or lever. If it is set to low, the water flow will be minimal, so adjust the flow as needed.

2. The water pressure from the tap may be too low. The water heater uses the pressure from the tap as the output pressure. In other words, the water heater must draw in water from one side to release water simultaneously. If the inlet pressure is too low, the water flow will be minimal.

3. The hot water pipe of the water heater may be clogged with scale, or the spray holes of the showerhead may need cleaning. It's also common for scale to clog the showerhead nozzle. The water pipes and faucets may also be clogged with scale, so you can detach them for inspection and cleaning. The showerhead can be soaked in vinegar or a descaling agent.

4. Regularly drain the system to prevent pipe blockages; clean the water tank to ensure water quality. When discharging, simply open the drain valve under normal water intake, and keep it open until clear water flows from the drain valve.
