In general, a booster pump is not required for a standard residential washing machine. Washing machines are designed to work with the water pressure provided by the main water supply in most homes. However, there may be some cases where a booster pump could be beneficial.
If you experience low water pressure in your home, such as in situations where the water supply is on a higher floor or the pipes are old and clogged, a booster pump may help to increase water pressure and improve the washing machine's performance. Additionally, if you have a large household with multiple bathrooms and appliances drawing water simultaneously, a booster pump might be useful to ensure adequate water pressure for the washing machine.
It's worth noting that installing a booster pump requires careful consideration and may require the assistance of a professional plumber. You should consult with a qualified expert to evaluate your specific situation and determine if a booster pump is necessary or recommended for your washing machine.
