Low Water Pressure: Possible Causes

  • Transcript

    LESLIE: Now we’ve got Lu from North Carolina on the line who’s dealing with a water-pressure issue. How can we help you today?

    LU: I don’t have any water pressure in my house and I wonder how to make the water pressure a bit higher.

    TOM: Now, has this always been a problem or is it a recent problem?

    LU: I think it’s always been a problem.

    TOM: Yeah. How old is your house, Lu?

    LU: Forty-three years old.

    TOM: Is it a well-water system or is it a city-water system?

    LU: I don’t know.

    TOM: Do you pay a water bill?

    LU: Yeah.

    TOM: Alright. So it’s city water, then, if you’re paying a water bill.

    So, then, what I would do is this: I would start by having the water pressures checked at the street and find out what the water pressure is coming into your house. It needs to be between about 50 and 80 pounds or so to give you decent water pressure.

    If there’s good water pressure at the street, then we have to go inside and start to figure out where it’s being restricted. It could be by the pipe, it could be by the water valve or it could be by fixtures. But if it’s evenly poor across the entire house, it’s more likely to be somewhere near the main water valve. It could be partially closed, it could be obstructed with mineral deposits.

    But I would start by contacting the water company and tell them that the water pressure in your house is not acceptable and then have them test the water pressure at the main for – where it comes into your house and see what’s going on. It could be that there’s a problem at the main that they could fix right there without even having to come in your house. OK, Lu?

    LU: OK, OK. I’ll contact them.
