How to Fix Weak Water Pressure
LESLIE: Bob in Michigan is dealing with a water pressure issue. What’s going on?
BOB: Oh, I have a house that I’m having pretty weak water pressure.
LESLIE: OK. Is it happening in just one faucet or are you finding it in all the faucets?
BOB: I’m finding that when I take a shower I’d better not have the dishwasher on or the laundry going. It’s happening pretty much in all of them.
BOB: I have a 3/4-inch …
TOM: Are you on well water or city water, Bob?
BOB: It’s city water. I’m the last house, pretty much, in the line of travel from the – that’s what I’ve been told; I’m pretty much the furthest out.
BOB: And they’ve metered it at 50 pounds pressure at the manhole.
BOB: And what happened is there’s a main there that there was a 3/4-inch line coming to the manhole from an old house that I demoed. And I hooked up a new house 100 feet away and connected a one-inch line to that 3/4-inch line to my house and now – you know, being by myself, I didn’t have a problem, but trying to sell this house later, I’m thinking, “OK, if there’s a family here, there’s going to be a problem.”
TOM: Right. Well, how about adding a pressure-boosting pump to that house?
BOB: I’ve been looking at that.
TOM: Yeah. I think that’s probably the best solution because that can bring the pressure back up where it needs to be.
TOM: You’re at such a far – you’re so far down the line there, I’m afraid that there’s nothing that you can do inside the house short of adding a piece of equipment that builds pressure back up that’s going to solve this. But if you add a pressure-booster pump, I think your water pressure is going to be where it is; everything is going to function normally. Because you know, even some appliances don’t function well if you don’t have the right amount of water pressure behind them.
BOB: That’s correct. My question was I looked into those pressure pumps or the booster pumps at the local hardware.
TOM: Yep. Yes.
BOB: And there seems to be some difficulty. You’ve got to have it right in the first part of the line.
BOB: Have you heard of maybe putting a pressure tank from like a well system where it contains water and then it pressures water from that point?
TOM: You’ve still got to have the pump.
BOB: Oh, OK.
TOM: Otherwise, there’s no way for you to build up the pressure. That would essentially be a holding tank.
BOB: OK. That sounds good. Yeah, well thanks a lot.
TOM: You’re welcome. Hope that solves it. Thanks so much for calling us at 1-888-MONEY-PIT.
