"We needed a new RO system as well as maintenance done on our current water softener system. Aqua Systems had sent over two technicians.. one headed into the house to install and the other to the garage to tend to the water softener. We were surprised by how quickly they finished. We will definitely contact them again for any future maintenance."

"Iâ ve been always wanting to get a water system but never got my hands on one until I met a one of their water specialist. He tested my water and showed me how contaminated was. After educating me on the cons of having "bad" water vs. "good" water, I was convinced I need a water system for my home. Iâ ve had my system for almost a year, and Iâ m very pleased with it so far. The team has been responsive and very professional too. I highly recommend it!"

"Klaro Water Systems did an amazing job installing a new Puronics whole home water filtration and softener for my home. They were thorough and professional. The thing I appreciated the most was the time they took to really listen to my concerns about our water quality and provide the right solution for our home. A+++"

"I was in the market for a water softener to which a sales person arrived to give me a quote. Infinity installs kinetico water treatment systems which is a proprietary system that you cannot work on. If you attempt to work on it yourself, you void the warranty of the system. They provided me with a quote of $3,600 for the softener, dechlorinator, and RO system which was a fair deal in my opinion. The only reason why I did no go with the company is that their service charge is $187 for each visit. That combined with the price of kinetico parts that are way more expensive than other brands. I m sure it s a great water softener, but the service charge fee is more then 3 times more than other competitors in the area."

"I cannot praise this company enough. The cost was a little higher than I anticipated, but I think it was well worth it. We woke up on a Saturday to a bathroom sink full of water and overflowing onto our floor. Turning off the water did nothing. Matthew from JD Precision came out that afternoon and immediately knew that it was due to our A/C condensation not properly draining. He drained the water, cleaned the drain pipes, and gave us tips on how to prevent it happening in the future. He then looked at a couple of other issues for us that we had been planning to get a contractor out for. He could have easily "taken us for a ride" on a couple of them, but he was totally straightforward and honest about what he saw and told us we could wait on repairs (and, save our money!). THEN, as he was leaving (and we had already gone inside), he went and checked our septic system for us. We had told him that our septic sprinklers had been going off a ridiculous number of times a day but that our maintenance company had told us everything looked fine. It took him less than one minute to find a hose that was not properly attached to the aerator pump. He obviously had no obligation to go out of his way to go look at our septic system - the fact that he did was just so kind. He then sent someone else out to take a look at what appeared to be water damage on our ceiling to be sure we didn't have a leak somewhere. That gentleman (who was also extremely polite and knowledgeable) took one look and said we are totally fine. Again, completely honest. We have some toilets to replace and a few other plumbing issues to address, and I will absolutely be hiring JD Precision again. I absolutely recommend them!!"

"Experience was good. We needed a new Water Heater to be installed. Show Plumbing was extremely accommodating, especially since we were out of the country the time that the work was done. Their office and technical members were professional, reliable and experienced. We also felt that their pricing was fair. We will use them again if we need and we would also recommend them."
