"The technician arrived at the start of the 2 hour window. On time! Very professional. Explained options for dealing with my toilet leak. I chose to replace the toilet and gave him guidlines for the new toilet. He went to Home Depot, acquired the toilet returned promptly and installed it in a timely manner. After which he broke down and explained the itemized charges. After paying for the work thru my credit card, I received an e-mail summary right away...One major concern that I had in hiring Western Rooter & Plumbing was that their technicians had been vaccinated for Covid 19. I had been referred to Western earlier this year by my condo HOA for a common area leak repair in my unit. I was assured by the dispatcher that the technician coming to my condo was vaccinated against Covid. So when I had this toilet leak problem 6 months later that I had to pay for, out of a multitude of plumbing companies, I went back to Western Rooter & Plumbing after receiving the same assurance."

"I recently ordered a new washer and dryer for our garage and upon delivery, I was told the washer couldn’t be installed because one valve was stuck and the other was leaking. One quick call to Rubio’s Plumbing and Robert had his guys here to replace the valves and install the washer. He also remembered that I had been meaning to replace our kitchen faucet so he said he could take care of that in the same visit. Brandon and Fernando were incredibly professional, helpful, and efficient. They switched out the valves, installed the washer, replaced my faucet, and made sure to clean up after themselves. I never hesitate to recommend Rubio’s Plumbing to any friends or family, and will continue to recommend them."

"Really great experience. Called AD3 after finding that faucet would not turn the water off after watering my lawn. Adrian answered and explained that he was on a job but he would get another plumber to come more quickly. He called back within a few minutes and said someone would be coming soon. Within 20 mins. A Diaz Plumbing van arrived and 2 very experienced and nice plumbers quickly got to work replacing the faucet! All of this occurred in less than an hour and the cost was very reasonable. Adrian Diaz and AD3 are now on my contact list. My water bill thanks them!!"

Sump Pump Installation FAQs, answered by experts

A water pressure booster doesn't require special maintenance. Like any house system, inspections should be a regular part of your annual schedule. Check for leaks, faulty valves, pressure loss, and mineral build-up. Pressure loss could be a result of mineral build-up, and you can descale the system with a vinegar and water solution.

Inspect the pump annually, test the float switch, and clean the discharge line to ensure efficient operation.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

Several indicators suggest it's time for a sump pump replacement. A key factor is age; if the pump is over 10 years old, its lifespan is likely ending. Performance issues are also clear signs, such as the pump running constantly, cycling on and off frequently, making unusual noises or vibrations, or failing to function at all. A faulty or burnt-out motor is another definite sign a replacement is needed. Additionally, if you notice any signs of incorrect installation, the pump should be replaced. For a definitive diagnosis, a vetted plumber can assess the pump and confirm whether a replacement is necessary.

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor.
