Very nice people, from phone reception, to sales, to in the field, very personel LOCAL service, appointment was set, then a sooner opportunity was offered when a cancellation occured. and it wasn't a canned sales speach it was a quick review they explained the different Filtering options and systms, used simple pricing. The prices were better then the "HoDo" and the "Hey" company Guys, at the time they were less than 7 days out for install, the installer texted his arrival time, reviewed the layout options with me when he arrived, installed it quickly, sent me a picture, and really is proud of his work Sales rep called during install to make sure i was pleased with the work. So yes, I like the company.

Response from the owner:Thank you so much, Carl! We appreciate your business and your kind, 5-star review!
I had 2 issues with my system. Christian came out quickly and resolved both issues and did a great job. He was very communicative and even sent me photos of before and after as I was at work. He kept me informed and the women in the office were nice too. Thanks for all of your help!!
Response from the owner:Hi Keith, thank you so much for taking the time to leave us a positive review! We're so happy to hear you had a positive experience with our staff, and we were able to get your system fixed quickly and efficiently.
This Easter lost water into house, called H2O systems at 6:13PM, left a message, Ashley called at 7:59PM, helped bypass solenoid valve to fill large 120 gallon tank, so I could take a shower. Now how many businesses would be willing to return a call on Easter, not to mention at night, and have the ability to correct a problem? Then next day make needed repairs. This isn't first time using this company - find technicians very thorough, knowledgeable, helpful, and courteous. Call, ask for Ashley, so you can also experience professional, courteous, and quality service.
Response from the owner:Thank you, Rick, for taking the time to recount your experience working with us and for the generous compliments about our service! Employee satisfaction means everything to us, and we're glad you had a positive experience with our team.
They find water. And do it with expertise.
Response from the owner:Thank you for this 5-star review, James! We appreciate you taking the time to leave us a positive review.
This company was amazing. When I called, I wasn't sure who could help me but Amber knew exactly what I needed and got to work. She helped with the city and the permit as well as all the work that needed to be done. They were quick and efficient and affordable. I would definitely call them again for any irrigation needs. Thank you so much for all your help.
Response from the owner:Thank you so much for this wonderful review, Lexie! We appreciate your retelling of your positive experience working with our company and staff! We hope to work with you again if any irrigation needs arise.
I've worked with H20 last 4 years through the builder I'm with, services have always been great, id recommend to anyone any day..
Response from the owner:Thank you, Amanda! We're so grateful for your partnership and for taking the time to leave us a 5-star review.
THE BEST COMPANY IN TOWN
Response from the owner:Thank you very much for your 5-star review, Amniel!
The technician that serviced my reverse osmosis system is named Dallas for h2o water systems co. i worked a 40 year chemical job and retired, so i still know quite a bit about pressures, differentials, valves and flows. i commend the scheduling lady, AMBER for sending DALLAS to change a membrane for an outside system. DALLAS is one of the sharpest, knowledgible and polite technicians, taking the time to explain what my system was and wasn't doing. He really put my mind at ease that i wasn't getting took for a high dollar maintenance job. Unfortunately, i have had this happen so many oyher times with a custom built dog penn not backing their warranty and also an attempt by an electric company not backing my 22kw generac whole house generator with an extended warranty, that i am very leary of any company that performs a service. HOWEVER, THIS IS NOT THE CASE WITH H2O SYSTEMS COMPANY!!! THEY ARE HONEST AND A LEGITIMATE COMPANY AND THEY SHOW UP ON TIME. I WAS SO IMPRESSED WITH DALLAS'S PERFORMANCE, that i even called the company and requested Dallas to do all of the work at my house and the company said they would work with that for me. This review is not stating that the company doesn't have other techs as sharp as Dallas, it's just a personal choice i have made and i am glad the company honored my request as i was just about to switch to another company that gaurantees everything for a much higher monthly fee!! I give h2o system compay the highest ratings for the way i was treated!!
Response from the owner:Thank you so much for this great review, Mark! We appreciate your honesty and retelling of your positive experience working with our company and staff!
I have had H2O services for many years already. They have never failed in providing the best service and sharp with details. Whe I call for questions or concerns, matters are teken cared of inmediately. Hard to find a company as good as they are. Thank you for such a great service!

We have used H2O Systems in the past and they have always been professional and honest, this time was no different. The technician, John, arrived on time, replaced a pressure switch, checked connections and pressure tank without additional costs, explaining the process to me. I would definitely recommend H2O Systems.
Response from the owner:Hi Sandy, Thank you so much for taking the time to leave us such a great review! We truly appreciate you trusting us with replacing your pressure switch! Have a great day!

Frequently Asked Questions

I have water that smells like rotten eggs. How do I get rid of that permanently?

A rotten egg odor usually comes from hydrogen sulfide gas in the water. The source may be your well, plumbing, or water heater. Permanent solutions depend on the cause and may include shock chlorination, oxidizing filtration, or water heater maintenance. A professional water test will pinpoint the issue and determine the best long-term fix.

Cloudy or yellow water is often caused by sediment, iron, manganese, or air bubbles. Weather changes, well disturbances, or aging plumbing can also contribute. A water test helps identify the exact cause so the right filtration or sediment control system can be installed.

Low pressure can result from pump issues, pressure tank problems, clogged filters, or plumbing restrictions. We can inspect your system, test the pump and tank, and recommend repairs or upgrades to restore strong, consistent pressure.
A full tank with no water flow usually indicates a pump, pressure switch, or electrical issue. It may also be a plumbing blockage. A technician can diagnose the problem and get your system running again.
Most water softeners work best with highpurity solar salt or pelletized salt. Some systems may require potassium chloride as an alternative. If you’re unsure, we can check your equipment and recommend the right type.
No water can be caused by a failed pump, tripped breaker, pressure switch failure, dry well, or plumbing blockage. We can troubleshoot the system, test the pump, and restore water service quickly.
City water often contains high mineral levels and disinfectants that affect taste and feel. A water softener and carbon filtration system can remove hardness, improve taste, and make water gentler on skin and hair.

Watering schedules vary by county and sometimes by address. We recommend checking your local county utilities or water management district for the most uptodate irrigation rules.

A water softener removes hardness minerals like calcium and magnesium, preventing scale buildup and improving water feel. An aerator system treats iron, sulfur, and some odors by exposing water to air and oxidizing contaminants. Many homes use both systems together for complete treatment.
Pump size depends on well depth, water level, household demand, and pipe size. A technician can measure your system and recommend the correct pump to ensure proper flow and pressure.

In many areas, yes. Irrigation systems often require a local permit to ensure proper installation and backflow protection. Your county or city can confirm the exact requirements.

A water use permit is an authorization, typically issued by a water management district, that allows property owners to withdraw groundwater or surface water for specific uses. Most residential wells do not require one, but larger or commercial withdrawals may.
