How do I know if I have low water pressure?
There are no specific numbers or ratings for this, so let’s keep it simple: if you are unhappy with your current shower and wished it were stronger, more powerful & more invigorating then in fact you have low water pressure. If it takes you forever to rinse the shampoo & conditioner out of your hair then in fact you have low water pressure. Low water pressure is not a number, it is a desire to get a better shower.
