anyone know how to increase water pressure in my house?

Is it the whole house or just one tap? If it's one tap or shower, unscrew the aerator or shower head and soak it in vinegar. Scale builds up in there and it's a five minute fix. Whole house, check the main shutoff valve is fully open first, they sometimes get left half closed after work. Then look for a pressure reducing valve near where the main comes in, a bell shaped brass thing with a bolt on top. Tightening that bolt raises the pressure. Get a cheap gauge that screws onto an outside tap so you know what you're working with, somewhere around 40 to 60 psi is normal. Don't push it much past that, it's hard on pipes and appliances.
