"We could not be happier with the Puronics Hydronex iGen Whole home treatment system and Micromax 7000 drinking water system provided by Orbit Water Solutions. Justin, the marketing rep who sold us the system, was very professional and accommodating. Justin took about an hour to demonstrate a series of tests which reflected to quality of our water which had more chlorine and hardness than we expected. If you have concerns for lead, Orbit standard demonstration does test for it so you will need to have a separate test done. After some negotiation, we were able to settle on a deal which got us the system and financing for the next 10 years. Orbit provides annual maintenance services on the machine and there is a lifetime warranty on parts which really assured us we were making an investment to improve our water. The best part about it is that the system travels with you. For a small fee, Orbit will pack the system up and ship it to your next home if you move which was a big selling point for us. Orbit also threw in a subscription to PureSelects soap for the next 10 years which was a nice add-on. PureSelects provides every kind of soap or cleaning product you could ask for so it will be nice not to have to purchase additional soap products in the near future. Within a couple days, the installation team came out to install the system. They arrived on time but the installation took a little bit longer than expected. Turns out our the installed garbage disposal was too large to fit with the RO unit tank under the sink. Orbit was very accommodating though. Orbit purchased a new garbage disposal and installed it free of charge which I bet many companies would not have done. I highly recommend getting the larger of the under sink tanks for the RO unit. Even with the two gallon tank, my family has used up all the water in the tank. A 1 gallon tank would just not have been enough. The water in our house has been incredible since we installed the system a few months ago. We noticed an immediate impact to our skin and hair after using it and our drinking water certainly tastes better. Best of all, we feel confident in the quality of the water we use throughout the house to keep us safe and our appliances in good condition. We highly recommend the investment in the water treatment systems through Orbit."

"National water has done a great deal of work for us. When we bought our house in 2001 NWS installed our water purification system any water related needs. I highly recommend them & we will continue to use their services. My husband pays the bills so I'm not sure about the fees but they know what they're doing, professional, friendly & honest."

"Wes showed up on time the same morning of my original call to Crown. He diagnosed my sump pump problem within ten minutes and I'm embarrassed to say it was a tripped GFCI circuit that my garage and backyard outlet shares. I should have known the first step of troubleshooting...check power source. After I reset GFCI in garage Wes verified the pump was working by observing several cycles. Sump pump replacement has been on my to do list for 15 year life and that's this year, so I'll be replacing both interior and exterior pumps in a couple of months. I'm going with a battery backup unit for the exterior sump. The prices for replacements are a skosh over the top end of my budget, but I'm impressed with the company, so I'll pay for the peace of mind."

"Great job by Jiffy. They had to pull a new water line under my townhouse slab foundation to replace the leaking poly water line. Pete Kristiansen, who is very knowledgeable and experienced, knew exactly what needed to be done. Plus it was a fair price. Highly recommend them."

"This is really a great company. Super-responsive, fair prices, and, most importantly, quality work done by knowledgable and hard-working folks. I initially called about a leaky kitchen faucet and the owner contacted me right away and was at my house within the hour. He diagnosed my problem immediately, recommended a solution, gave me a reasonable estimate, and said it would be taken care of that day. I was so impressed that I decided to ask for a quote on replacing an aging sump pump and water heater. I wound up having those replaced as well. They also installed a frost-free spigot in front of the house when I mentioned the issues I was having with the ancient "vacuum breaker" that sprayed water everywhere and that I simply could not remove myself. Now flash-forward to 2 weeks later: I detected a water-stain on my living room ceiling which I deduced was probably coming from an upstairs toilet. I called after hours and left a message describing the problem. The owner called me early the next morning and sent sent somebody out immediately. The issue was determined to be a deteriorated "wax ring". Rather than doing a repair, I decided-- at no urging from them-- to have both of the 30-year old toilets in my house replaced with new units. The job was done quickly and professionally in just a couple of hours. Few things are as stressful to homeowners as plumbing and water-related issues. However, it is a relief to know that there are competent, responsive professionals out there like Kelly that you can turn to when the need arises."

"A new sink was needed to be installed on the second floor for a remodel. After demos was complete AJ gathered all materials he needed for the job quickly got started. He made sure that everything was done accord to code and even tested the lines for leaks after he was done. Overall I was 100% satisfied with the work that was done and I will definitely call him back again."
