"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."

"Sila was great about scheduling repair visit same day. Repairman showed up early (good), diagnosed problem before he even got to the unit (bad capacitor, buzzing), had part onboard truck, and then fixed it in less than 20 minutes, total visit. Charged me $439. Cost was $149 for diagnostic/visit + $290 for replacing the part. Repair was so quick that it was less labor than would have been required for a more common diagnostic. Since doing research after the visit, I'm of the opinion that the cost was excessive -- perhaps twice what it should have been. Service was good, but I would think twice before using Sila again, say, to replace this 17 yo system down the road."

"There were issues like a portion of pipe under the sink that needed fixed as well as re-doing some of the valving that was leaking water. The guys also didn't have part with them and had to go out and purchase what they needed to do the job correctly. They also had some issue with reverse osmosis system due to the complicated set up. However they figured it out and the job was done in about 4 hours. They were very professional and cleaned up. Even helped put things back under the kitchen sink that had to be removed so that they could install the RO system and do the other plumbing work."

"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."

"Gary arrived on time and was very professional and went straight to work on my water heater problem. He explains things to help the customer understands and he is very reasonable and will not take advantage of customers like some of these other plumbing companies do. I was very pleased with his work and will use him again without a doubt and will recommend him to others. He is a blessing. He did a great job!"

"It went really well. Mr.Kelly and his team were very professional. I didn't know anything about repairing and cleaning a gas fireplace, but Mr.Kelley took the time to explain everything to me. I really appreciated that. I will definitely use them in the future. I would also recommend them to family and friends."

"

This was a big deal service. He did not charge me too much for it and my toilet has been working great ever since. I don't know what his name was, but I called them for my daughter recently. He was professional, did his thing, fixed my toilet and I have not had an issue since. He was a good guy and a nice person.

FAQs for water treatment & purification system repair or service projects in Washington, DC

If your water softener is over 10 years old or if repair costs approach the price of a new unit, it might be time to replace it. Most water softeners last between 10 and 15 years. Replacing an aging unit can improve your water quality and help you avoid frequent repair costs. For a newer system with minor issues, repairing may be the best option. Consider the age and condition of your system to decide what's most cost-effective.

Water treatment systems remain dependable for 10 to 20 years with proper maintenance and care. A well-maintained system secures full performance by following a scheduled upkeep plan and professional inspections. Consistent maintenance guarantees continuous water purification, ensuring that the system operates at its peak efficiency and delivers high‑quality water throughout its lifespan.

Faulty water softeners exhibit clear symptoms that signal the need for immediate attention. Noticeable mineral build-up around faucets, discolored water, dry or itchy skin following a shower, and altered laundry texture indicate that the system is underperforming. Recognizing these issues early and addressing them promptly prevents further damage and maintains optimal water quality. Early intervention ensures that your water system continues to operate reliably and efficiently.
