plumbing problems?? water pressure?

we just moved a new house the looks like it hasn't had work done on it for a long time. i noticed that the water when i'm showering sometimes lowers preassure and i thought it was because someone was using the other water sources alson in the house but when we hooked up our chothes washer we realized that water preassure would lower for no apperant reazon it so weak sometimes we called a plumber and just analyzing will cost us 200 hardearned dollars. any one got any suggestions about what it could be thanks

1. depending on the age of the home and the kind of pipe the used to feed the water it could be buildup/rust if it's an older home w/galvenized.
2. your water heater may be full of lime and calcium, this is a common problem, also just after the main pipe from the street comes into your house there is a preasure regullator it may be set to low or worn out,
3. Check in your garage for a Pressure Regulator. I have one here in the house I'm renting. Had to turn it up
4. water meter or mean valve.
5. If you have a water pump this is normal as the pressure goes down to 30 psi before pump kicks on and off at around 50 to 60 psi.
