 Trustindex verifies that the original source of the review is Google. Jacob at Trusted Water Systems was a referral and one we’re grateful for! We needed a second opinion assessment of work recommended by a large plumbing company and a quote for the work. Jacob responded timely (and while on vacation!) and came out within a couple of days (non urgent.) His quote was significantly less and he explained why one of the other company’s recommended services was not actually needed. Hired him do what was needed which was completed at this appointment. Clearly very knowledgeable, provided helpful info about water heaters, and zero upselling! If you have any water heater needs, definitely consider Jacob!

 Trustindex verifies that the original source of the review is Google. Getting a new water heater can be daunting, especially if you have never had to do this before. I reached out to a few companies and none were as willing to take the time to describe the whole process. Jacob was professional, on time and finished quicker than planned. Highly recommend him for your water heater replacement needs.

 Trustindex verifies that the original source of the review is Google. We had a fantastic experience replacing the old water heater with Jacob at Trusted Water Systems.   He was prompt, and kept us updated on his arrival status. The water heater was neatly installed with updated piping leading to the water heater itself. We are so glad we gave Trusted Water Systems the job and would highly recommend them.  The price and the #Warranty were the best!

 Trustindex verifies that the original source of the review is Google. Just like the name of this company, Jacob (with Trusted Water Systems) was very honest and upfront with his assessment. His deep understanding, and the care to which he addressed the nature our particular waterless heating tank, assured us he would deliver on getting our unit fixed. Trusted Water Systems was a pleasure to deal with and we would not hesitate to do business again.

He answered all of my questions without any pressure or wasting my time, which I really appreciated. Joseph did an amazing job installing our new water heater. He worked quickly, efficiently, and left everything clean when he was finished. The whole process was smooth from start to finish. Their pricing was very reasonable, and I felt like I received excellent value for the quality of work. If you’re looking for a trustworthy company with great customer service, I highly recommend Trusted Water Systems!

 Trustindex verifies that the original source of the review is Google. Joseph was great . Called at 10 with no hot water . He was here by 2:30 and I have a new water heater by 6:30. He was thorough, replaced just about everything and was pleasant when I was bugging him. I highly recommend him and his company.

 Trustindex verifies that the original source of the review is Google. 10/10 experience with Jacob from Trusted Water Systems. Worked with me to find the right water heater for our needs and worked around our schedule for the install. Great install and a solid guy. We've already scheduled a water softener and water filter install with him. Can't recommend enough!

 Trustindex verifies that the original source of the review is Google. Fair pricing, prompt service, and high-quality workmanship. that's exactly what I experienced with Trusted Water Systems. I contacted them over the weekend after noticing my 10yrs old water heater was leaking, and Jacob responded quickly with a fair quote and got everything scheduled right away. Joseph arrived on time and did an outstanding job. I've hired many plumbers over the past couple of decades, he provided one of the highest-quality plumbing services I've ever experienced. He was professional, detail-oriented, and dedicated to delivering top-quality work.. The installation was clean, and everything was done the right way. If you're looking for an honest and reliable plumbing company, I highly recommend Trusted Water Systems.

 Trustindex verifies that the original source of the review is Google. He had previously installed a water heater at our home and we were quite pleased. We had him back to replace the one at our rental. His price was very good and it included cold water shutoff valve and expansion tank which others had  not included.

 Trustindex verifies that the original source of the review is Google. Jacob was outstanding. He worked quickly and did a wonderful job at a very fair price. He showed me how to fill the tank, and is readily available if I have questions or need help. I’m recommending him to friends and neighbors, something I reserve for only the very best.

 Trustindex verifies that the original source of the review is Google. We had a water heater failure resulting in no hot water and contacted Trusted Water Systems after doing a bunch of research.  They committed to installing a new, replacement water heater the next day.  Joseph handled the installation and he was simply great.   Due to parts availability, the installation started later in the day, but Joseph stuck with it until completed, double and triple checking the key gas lines.  He didn't leave until after 9:00 PM but we, once again, had hot water.  Thanks Joseph, really appreciate the effort.
