"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

Backing up? Got roots? Blast those roots out with a Hydro Jetter! We use a wart hog nozzle that combines controlled rotation with a unique 8 jet cutting configuration optimized for removing roots. It’s better with a jetter! Call us! We got this! ??

"Anthony has done a wonderful job replacing my bathtub pipes at an extremely great low price. I highly recommend Rotor ER & Plumbing Inc. I panicked because I saw water on my downstairs ceiling because my bathtub upstairs was leaking showing the rectangular water print on my downstairs ceiling. I quickly called ER & Plumbing Inc. and Anthony came out immediately (same day witihin 30 min) and quickly assessed the problem. The pipes under the tub had a huge leak on a fairly new home (6 yrs old). The pipes were to large for the area under the tub which caused the pipes to crack. I am disabled and needed to soak my fractured back. Anthony showed up the next day with new pipes and all of his equipment and fixed the pipes the same day. Wonderful job and at a reasonable price. Very friendly and polite to. If ever I need plumbing again I will definitely call them and highly recommend them. Thank you Anthony and Phillip you guys are great!!!! ;-)"

"Excellently well! Sandy helped me coordinate the inspection expediently. We were on a tight timeline and she pulled some strings so we could get the inspection done in time. Our inspector/structural engineer, Erinn, was personable, thorough, knowledgeable and timely. I highly recommend him and Alpha Structural!"

"My husband and I have been thinking for several months to get convert our backyard to a drought tolerant landscape. We want to lower our water bill as much as possible and revamp our yard and get it ready for summer. We decided to hire Motti because we felt he gave us the best presentation of ideas for the yard and his background knowledge of landscaping. We had our grass ripped off completely and remove very old sprinklers. The crew planted about 50 California Native and desert type plants with a new irrigation and removal of a Yucca type tree, with stump and roots. DG and rocks were also installed. Overall the project came out great. We are happy and will call Motti for our next project (Front yard)."

Drain Pipe Installation FAQs, answered by experts

Keep your egress window from flooding by ensuring that the drainage system in the window well is clear and in good working condition. Inspect the window well every few months to remove any blockages and test the drainage system. It’s better to discover potential problems before your window well fills with water during heavy rain.

Even if the shower drain doesn’t seem clogged or dirty, plan to clean it out about once per month—or more frequently if you or your family shed a lot of hair. It’s a good practice to remove any hair from the drain on a daily basis, as hair can accumulate fast and cause clogs in no time. You may also want to have a plumber thoroughly clean the drains in your home once every six months.

Baking soda and vinegar aren’t just great for making a volcano for your kid’s science project. You can also pour this dynamic duo down your shower drain to dissolve hair clogs. If that doesn’t do the trick, you can step it up with a commercial liquid drain cleaner. 

Several signs can tip you off to a clogged dishwasher drain. At first, you may notice that it’s taking longer than usual for the dishwasher to drain, or you may hear gurgling sounds during the draining part of the cycle. You might also notice water backing up into your sink or excess food at the bottom of the dishwasher after a load. The most obvious sign, though, is seeing standing water at the bottom of your dishwasher after the cycle has finished.

While you don’t have to run out and immediately buy a new toilet at the first sign of a clog, if the toilet keeps clogging because it’s a low-flow or poorly designed model, a new toilet may be the way to go. If your toilet keeps clogging, you can try using less toilet paper, adjusting the fill valve, checking the toilet vent pipe on the roof, and using a toilet auger to make sure nothing is stuck in the pipe or trap.
