Recommended Customer Reviews

When I had issues with the well pump, I called the Cal-Tech team. They came out very quickly, assessed the problem, provided worst case scenario estimates and next steps on fixing the problem. They were able to come out a few days later, pulled out the pump and determined that it was worn out. Luckily, they had a new pump in store, so it was replaced the same day. They were very methodical and attentive to every part of the system. They reviewed all the components and assessed their state, assembling them with longevity and ever wear in mind.
I peppered Scott and Joe with questions, and they patiently answered all the questions every step of the way. They educated me about all parts of the well pump and the best way I can keep an eye on it in the future.
I appreciated not just the prompt response, but also the attention to detail in their work and willingness to educate their clients. I would definitely hire them again.

This guy helped me trouble shoot my well pump. Fixed over the phone in 2 minutes. Really appreciate his help and will be hiring him for a real project when the time comes. Much appreciated sir!

It would be hard to know less than I do about wells, pumps, and all the other %$&*@ that goes with it! Call CalTech Pumps. Scott Brown probably doesn't know everything, but compared to me he is a magician and a genius! I'm serious. He'll give it to you straight, humble as he is knowledgeable, as friendly as anyone I've ever hired to work for me, as prompt and reliable as one could hope for. He is the real deal and charges you fairly, for sure. Highest recommendation!!!

There is no greater authority when it comes to water, pumps and filtration. I know nothing about any subject I just mentioned but needed an authority that could assist me with all of the above, lead me in a direction that would bring me the greatest value so as not to break the bank and yet meet the quality I'm seeking for my family - Scott hit all of the boxes plus some I failed to plan for. After decades of buying bottled water for drinking and cooking Cal-Tech Pumps has greatly improved our quality of life. What a rockstar!!

I was very impressed with the immediate response from Cal-Tech Pumps. After discussing the problem on the phone I was told what the problem was and how to fix it myself. I asked if he could respond as I wanted a professional to handle it, both Scott and his son, Joe came out the next morning. They fixed the problem immediately. Thanks guys.

Cal-Tech Pump has helped us with numerous projects. After the Valley Fire demolished our properties and home, they got three of our wells up and running again. They've helped us test our water and well too. I can always rely on them to perform a quick, efficient, honest and thorough job. I recommend this company to everyone.

Scott and his wife are terrific. We are pretty clueless when it comes to wells and pumps. They are always available Monday to Sunday (yes Sunday). They're always friendly and super helpful and besides that scott is doing a great job.

We are on the lake. We needed a water system, I found Scott and couldn't be happier. He is nice and honest and always gets back to you if you have a concern or problem. I would highly recommend him!!

I work with hydronic myself my aunt up in Lake County needed a needed a repair on her water well..
She wanted me to look at their work and they did an excellent job they have reasonable prices and do Superior work.. I recommend them for all your well works.

I was referred to Scott Brown by pump company in the phone book. I was a first time well owner and I needed an evaluation of my equipment. Scott came right out the next morning and taught me all I needed to know to monitor my pump and know when it is time to worry. Despite it's age (20 years) he did not try to get me to buy new equipment and he gave me the good old...""if it ain't broke...."". He answered all my questions, and wrote down the information about my pumps energy use and made me feel like a valued customer even though it was just a ""look-see"". I always try to give a thumbs up for great experiences and this was one. When I do run into trouble with my pump I will not hesitate to call Cal-Tech Pump. Everything he had to say about pumps and interfacing showed he had experience and was dedicated to having pumps matching well to the location and application they are needed.
