"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."

Tru plumbing mechanical
Tru plumbing mechanical
Tru Plumbing Mechanical is a new plumbing contracting business that I started in March 2022. When I started plumbing, never in a million years did I think that I would love it this much. I love the challenges it brings and the headaches it causes! When it comes to family homes there is no job too little or too big that we can't handle because we understand the value of piece of mind and that is something you cannot put a price tag on. We are a veteran-family owned and operated. A little about me the owner/technician; I proudly served in the US Navy from 2001 to 2009 as a Fuels repairman. I have been around the world, I have spoken to a lot of different cultures and backgrounds. I have learned and lived the Navy's core values which is Honor, Courage, and Commitment in which I carry with me till this day and that is what I will bring to my customers.
"He was able to fix the issue, got it done quickly, and he's a nice person."

Easy Rooter Plumbing and Drain Cleaning
Easy Rooter Plumbing and Drain Cleaning
Hello and thank you for taking the time to get to know what we here at Easy Rooter Plumbing And Drain Cleaning are all about. I will get straight to the point. I have been in the emergency plumbing and drain cleaning service industry for the past 13 yrs. I started in one of your everyday typical rooter service companies and quickly began to realize that I loved working with people. I also realized that I was not too fond of the way the big corporations treated and micromanaged employees as well as viewed clients as nothing more than potential dollar signs. This allowed me to absorb as much as I needed on the technical side in order to start up my very own business. It took 8 long years to acquire the skills and resources needed to fully service and provide the best solutions for my customers. I am so happy and blessed to say that we now, 5 years later, have 6 full service trucks ready to serve you and your neighbors 24 hours a day seven days a week!
"I must admit my experience with Easy Rooter Plumbing and Drain Cleaning was amazing. As soon as I completed my online request for professional services (noting the urgency of our plumbing situation - both toilets down, low water pressure in some faucets, and no pressure in others, and brown goop with black specs flowing from all faucets ), my phone rang. It was the representative from Easy Rooter assuring me that she could have someone here to help within the hour, and she did. Juan arrived and quickly assessed the problem, and calmly explained exactly what was happening. He was very up-front about what could be repaired, needed replacements and the required flushing of the entire plumbing system. Juan was knowledgeable and professional throughout the ordeal. He turned a financially impossible situation into manageable monthly payments, with a reasonable interest rate, and spread out over 10 years if needed. He provided two payment options, with two very different overall costs and potential outcomes. My husband and I decided on a course of action, agreed to the terms of the contract, then we were all set for repairs to begin the next a.m. Juan explained that as the previous owners vacated the house (approx 3 yrs ago), they made sure to shut-off the main valve to the water softening system, but neglected to shut off the bypass valve. This allowed the water and remnants from the holding tank to seep back into the water softening system, then back through the pipes in the house. Certain parts were severely clogged and others damaged. Juan and his partner arrived on time the following morning as scheduled, and proceeded to restore clean and clear water throughout the house, and remove whatever was restricting water flow. The contaminated water softening system was replaced, and all new valves installed. Once programmed, the new system flushed all pipes and will continue to do so weekly. The team worked diligently for approx. 9 hours. When done all was running clear, and the pressure restored. They even hauled away all debris. My family is very thankful for Easy Rooter for being prompt and for paying close attention to detail. I would not hesitate to refer them to family and/or friends or to call on them again if needed."
