We just bought our home in March and have noticed that when the outside spigots are open and water is flowing it makes a strange moaning sound. If left open (water flowing) the sound can be heard inside the house whenever water flow stops;i.e when flushing the toilet after it has stopped filling, we hear the moan. We only hear it in the house if the outside spigots are left open and water was running then stopped flowing. The backyard spiot is worse. If left open we hear the moan and water will spew out from between the hose bib and hose after a toilet is flushed or I have shut the kitchen sink off after washing something.
I have no idea why this happens as this is our first home. We also have very hard water if that matters.
Anyone have any clue as to why this is happening and what is to be done?
In the Phoenix are the builders didn't always put the extra hardware on the waterlines to avoid the noise. This goes as far back as in the early 1980s when I had my home built and asked the builder to install water-hammers on the lines. They didn't know what I was talking about and insisted that everything would be fine without them. Later after the home was completed and we moved in, I noticed the knocking and noise in the waterline. The worst one was in the master bath & shower. I talked with the builder and they sent the plumber back out. They told me that nothing could be done at this point in time because the tile in the shower was already installed and they couldn't get to the pipes. However they did however install a regulator on the main waterline to the house to reduce the pressure. That helped but it wasn't perfect, but any improvement was better than none. The builder was a contractor that was highly recommended by the relator we were working with. Phoenix water pressure is higher than some cities and that might be a cause of your problem. Add a water-hammer or a pressure regulator.
No knocking sound. And I still don't understand why water would spew out of the back one when we stop water flow in the house. Doesn't make any sense to me.
I don’t understand, are you saying the faucet on the house for the backyard is leaking water even though it is turned off? I’m assuming “spew” and “leak to be one of the same here. If the faucet is turned OFF there should be no water coming out of it regardless of whatever is being or not being used inside the house.
There is (or should be) an ant-syphon attached to the faucet on the outside of the house. If you have a garden hose with a sprayer attached to the faucet and the sprayer is turned off, there will be a “splash back” or “spew” of water that comes out of the ant-syphon device. Is “that” what you’re talking about? Water coming from the ant-syphon device?
Look for an extra metallic fitting that might have been screwed onto the end of the hose bib - perhaps brass in color. These are the backflow preventors that are common in many areas. In our previous home we had to install these fittings on our hose bibs before selling our older home. The hose would then be screwed onto this fitting.
If this fitting is present, see if it can be unscrewed from the hose bib and then test the bib with the hose re-installed to see if anything has changed (i.e. no more moaning or spewing). However, some of these backflow preventors cannot be easily removed from the hose bib because there is a lock screw that the user is typically instructed to tighten until the head breaks off. The authorities like these because the home owner can't easily remove them after they are installed. However, they can usually still be removed with a bit of finagling. A new one can be purchased at Home Despot for around $5.
How is your water pressure and flow overall? High, low ?
