Great service!
I called for a concern I had with my system. Their technician, Dallas, conducted a thorough diagnostics check, found exactly what the issues were, and explained the causes and effects of my options. I did opt for the full repair and service with full confidence that it will be done properly and professionally.

I greatly appreciate the services that this company provides with awesome employees like Dallas, among others.
Response from the owner:Hi Fisal, Thank you so much for taking the time to leave us such a great review! We appreciate your business!
This is the second time we’ve had to have a submerged well pump replaced in ten years. We’ve used them both times. They’ve raced right out, diagnosed the problem and repaired it immediately. Glenn worked extremely hard pulling 90 feet of PVC with the pump attached out of the well and putting the new pipe and pump back in. He was kind and knowledgeable, answered all our questions, and didn’t leave until he was sure we had water back on. Extremely happy with this company and would recommend them to anyone looking for a professional well service that not only answers the phone, but runs out to get your water back on. Thank you so much H2O!!
Response from the owner:Thank you so much for taking the time to leave us this recommendation! We're glad Glenn could assist you effectively and restore your water service promptly. Your satisfaction is our priority, and we appreciate your trust in us for your well and water needs!

My Well Water pump overheated! The Techs came within an hour. They were very knowledgeable, professional, easy to work with and the Tech explained everything to me.

I was referred to H2O by my plumbing company Waterworks, and I’m very satisfied with this company. The technician, Glen, called me to give me his arrival time, and arrived when he said he would. He thoroughly diagnosed my water system issues. He was knowledgeable, professional, patient and friendly. He answered all my questions and recommended a new well and reverse osmosis system, which is exactly what I assumed I needed because my well and system are pretty ancient.
I’m looking forward to working with H2O on the installation, and will update my review once the system is up and running. 👍😄
Response from the owner:Thank you for your 5-star review, Laura! We're thrilled to hear about your positive experience with our company and staff. We appreciate your trust in our services and look forward to installing your new system. We aim to provide top-notch service every step of the way!

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.

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.
