"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."

"My well pump pressure tank needed service and I called Friday and Barbara was very professional and eager to help. She took the time to understand the issue and even reviewed the pictures. Barbara is very passionate about her job. She was able to schedule for Saturday. Dave came out. He called to let me know that he was on his way and let me know when he will arrive. He was very punctual, professional, friendly, and down to business. Totally impressed with the way he solved the problem and made sure that answered all of my questions. This company is very ethical and I would recommend them to anyone."

"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."

"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."

"I really like this guy.  Most companies would not take the time out to really take that extra step and see what’s really gone wrong.  Every time I call this guy with a problem, he rushes out to take care of us.  I can’t say enough about him.  We didn’t have to pay him anything because it was under warranty.  Even though he knew he wasn’t going to get paid for the service, he came right out and that’s what impressed me.  He’s just amazing in general.  We had a problem with drain flies last time and we couldn’t figure out what was wrong.  So we had one plumber come out and he just said that we needed to call him again.  We did that and they came back.  They told us that it was a drain fly that is usually associated with the toilets.  We called a plumber and then another guy came out, and he didn’t see anything wrong.  The guy from Pressley Plumbing noticed that there was a crack in our pipe and he found that out down in the basement where the hole was.  He had already worked on that and the pipe had cracked open on the inside of the house.  Then he came and figured out that there was a root that had actually grown into the pipe on the outside of our house.  He showed everything to us through a video.  It was pretty bad and he set it up, so that we didn’t have to worry about anything.  He really took care of things and made sure that everything was replaced on our walkway.  He replaced all of the dirt and he called the right people to take care of the line.  He took care of everything.  He also called the county to see if they could cover any part of the cost.  He also called the insurance to see if they could cover the cost.  We didn’t have a lot of money and he really worked with us on all avenues.  So that’s why we called him back again when our water heater broke.  He’s just a really good guy.  He has consistently delivered for us.  He comes in and respects the property.  He’s always on time and he makes sure he’s clean.  If he’s not on time he will call.  He’s really good at what he does and he’s very honest.  We will use his services again in the future."

"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!"

"We needed a filter removed from our system in order to replace or repair a broken washer/dryer unit. Kelly was able to come out within 24 hours of contact and performed the work at very close to the estimate that was given sight-unseen. They were early, worked efficiently and completely cleaned up before departing. Will definitely have them out to quote on some larger projects around the house."

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.
