"Western Rooter to the rescue again! I had a small underground leak which appeared to be due to a bad sprinkler valve. A sprinkler repair company determined that it was not a bad sprinkler valve and thought it was due to a leak in the main water line. Daniel and Alex dug down to find that the leak was coming from a very old (at least 36 years) broken pvc line. After much testing and head scratching to try to figure out where the water was coming from, they decided to "chase the pipe." After much digging, they found that the very old broken pvc pipe was hooked up to a sprinkler valve that was buried 18 inches underground that had not been capped--only turned off. Roots from a nearby tree had opened the valve which caused the leak--crazy! The current sprinkler system has been the same one since we moved into the house in 1988. It took 36 years for the underground leak to occur!"

"I had an excellent experience with Pro Bright Construction. They responded to my initial inquiry very quickly and were able to schedule the installation of a whole-home water flow restrictor on the main water intake that same day. The two professionals who completed the work were friendly, knowledgeable, and courteous. Although this was a significant installation, they finished the job in just a couple of hours and left the work area spotless. I was quoted a price by a large plumbing company that was nearly twice the amount I paid, so I also appreciate Pro Bright's very fair pricing. I'm left truly happy for their prompt response, professionalism, quality workmanship, and value. I will definitely contact Pro Bright Construction for any future plumbing needs and highly recommend them."

"I was in dire need of a plumber because the valve that adds water to my pool was broken and it would not shut off. We had to shut off the water to my house to prevent flooding of the pool. Enter Rooter ER & Plumbing to the rescue. He was extremely knowledgeable about what was required just by looking at the picture I sent over the phone. He gave me options and quite reasonable prices. Doing the work, he was extremely efficient and thorough. He would not stop until it was up to a standard that he expected of himself for his own home. When I went out to look at/inspect his work, he was extremely patient and he explained to me everything that he had done and the benefits of getting this done. Being a complete novice in the realm of plumbing, I was extremely grateful for him taking the time to explain this to me. I was extremely happy with his work, and I would recommend him to anyone that needs a friendly neighborhood plumber."

Water Softeners FAQs, answered by experts

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.

No, a water descaler won't descale pipes. The charged water running through the pipes may very slowly dissolve mineral deposits and hold them inside the water, but it's a very gradual process. If your pipes do need descaling, it's much better to get a local plumber to descale your pipes.

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.

Most of the U.S. has hard water, especially across portions of the West and Midwest. The areas with the hardest water include parts of Texas, Oklahoma, Kansas, Colorado, New Mexico, Utah, Wyoming, Illinois, North and South Dakota, Ohio, and New York. You’ll find soft water in parts of New England, the Southeast, the Pacific Northwest, and Hawaii.
