We were patched through Oasis via Costco. [[HIGHLIGHT]]Izzie came by the next day for his presentation. We made it clear we were just getting quotes and comparing and he was respectful of our time with his presentation.[[ENDHIGHLIGHT]] After comparing prices with other companies, we decided to go with them. They were willing to negotiate and offered us a military discount which sealed the deal for us. However, the only reason why I didn't give them 5 stars is because from the date of sale, we waited about 6 weeks before they could actually schedule the install. We were told they could install the softener internally to avoid HOA politics but on the day of service, we were told this was not possible, although they did make an attempt. We ended up having to buy a shed which pretty much came at the cost of their discount and going through our HOA anyway. They came back the next day to finish the job. Overall, we were very happy with the service they provided despite that hiccup. Would recommend them for their service and professionalism. read more

[[HIGHLIGHT]]I've called several times and left messages via their website but have had no return correspondence.[[ENDHIGHLIGHT]] I have a water softner system of theirs flashing messages of needing service and no way to get anyone to come out and provide service. [[HIGHLIGHT]]Not even a "We can get to you in a few weeks" message.[[ENDHIGHLIGHT]] read more

[[HIGHLIGHT]]I think they are out of business, they do not return any calls and no one answers the phone.[[ENDHIGHLIGHT]] [[HIGHLIGHT]]I can no longer get service on my Ecowater system as there are no other dealers in San Antonio and even the corporate Ecowater site does not answer.[[ENDHIGHLIGHT]] I replaced the resin myself with high quality 10% cross-linked I found on the internet (buy new gravel, it was a pain recovering it from the old resin and is required for an Ecowater). That resin should last 10-20 more years if the valve seals last and I probably saved a ton of money. If not reparable due to parts, I will self install a Fleck 5600SXT since those are simple and all parts are available online. Hope this info helps someone else and if you need tips, send me a message. read more

Had a service tech come out a year ago only to try and upsell me on filters even though mine worked just fine. I only use it for drinking water and coffee and only for myself. The output water was tested and had maybe 3ppm and he suggested new filters bc they were "old". Who cares? $160 just to walk in the door. Today it'll cost you $220 to walk in the door. I can buy a whole new system for that. Jokers and finally acknowledged I could buy a new system for another $200 instead of using their 'services'. Ppl gotta get paid. I get it but the integrity is an issue. read more

[[HIGHLIGHT]]I normally receive service in November of each year.[[ENDHIGHLIGHT]] I received the normal email from Oasis to contact them to schedule service. [[HIGHLIGHT]]Over the last month I've left four (4) voice mail messages and sent two emails requesting service without even a call back or return email.[[ENDHIGHLIGHT]] I'm concerned about my water system. Either they're that overwhelmed or have gone out of business. [[HIGHLIGHT]]Zero customer service.[[ENDHIGHLIGHT]] No choice but to contact Costco next for a solution. read more

[[HIGHLIGHT]]I have been trying to request maintenance appointment since August 26 (over 6 weeks ago), but cannot get response by phone, email, website or social media.[[ENDHIGHLIGHT]] While my request is for maintenance, I am concerned that system can be negatively affected if service not performed. I tried reaching out to national provider for alternatives, but no response from them either. In prior years, I had good service from this company, so extra disappointed in recent history. read more

i installed the water system on march 2024 but now it stopped working on April 2025 . oasis water solution told me to pay $220 for someone to come to diagnose. paying money for labor to come after bought their system more than $6000 but working only a year. Also you have to pay main fee (labor fee) $220 per annual visit. i bought this system because i love costco but their services are terrible. [[HIGHLIGHT]]they tell me to call me back but there's no call at all, even they know my system broken and need to fix asap.[[ENDHIGHLIGHT]] Doing business also need to keep prestige! read more

Recently moved into our first home; a water softener was a top priority. Initially called Oasis as they partner with Costco, and come on - who doesn't love Costco? In the end, l lost respect for Costco and their choice of "partners". The day of, the salesman arrived and put on a great "show". He ran several tests on the water, had me shake some beakers, etc. He also explained the recommended softener thoroughly. This is where it went from almost impressive to ..."Oh, HELL NO!" I made it clear, before he tested ANYTHING - I was NOT looking to purchase; I was still comparing companies. Additionally, I made it PERFECTLY clear we JUST MOVED IN, and were making "new homeowner" budgeting adjustments. Bottom line: he didn't give a rat's ass about what I said. The same questions ...as to why I couldn't make a decision that day, were asked repeatedly. Toward the end, I repeated, "I'm not making a decision today"..."I'm not making a decision today" - probably 20 times. No matter - same questions....same "confusion" as to what held back my decision. Growing frustrated, I kept repeating, "I've already answered that" and "I'm not making a decision today". I easily repeated myself 20-30 times. At one point, the salesman laughed; I didn't. Finally, he needed to text his "supervisor" he was wrapping up. Before I knew it - the "supervisor" called..who had him on the phone far too long. Once off the phone, he threw the last gimmick. Suddenly, a GREAT DEAL was offered on another softener, at a lower price. Again, repeated, "I'm not making a decision today" about 10 times. Then, I made a comment that if the deal offered me was that great - it'll be around when I'm ready to make a decision; he replied it was "take it or leave it" - today only. THEN IT WAS BACK TO THE QUESTIONS! Why I couldn't made a decision today, etc. Finally, I had enough. I told him, calmly, he was PISSING ME OFF; not only had he lost my respect, but also my business. Making me repeat myself that way, and not taking "NO" for an answer went beyond anything I'd ever experienced. By the way - these guys were - BY FAR - the most expensive of the companies I researched. read more

If you're in the market for a water softener, look no further than Jason with Oasis. Oasis and Costco have teamed up to provide the best system & there is no better customer experience/service especially for our Military/Veteran families. Their warranties are costs can't be beat. I called and met with over six representatives for various companies, and landed on the best. read more

Way out when you sign any paperwork with them! I have the carbon copy of what we signed with the and they added stuff to the paperwork to send to the credit company we are now have been charged over $2500.00 more than wha we signed the agreement for. Do not leave one line open for them to write in because they will. read more

I called for an estimate and to clarify some information, but they DIDN'T return my call in 7 days. No one answers the phone. I then started reading previous reviews and found that some waited 9 weeks just to install the water softener. I changed my mind and chose a different water softener company instead. I felt like I dodged a bullet because if they couldn't even bother to return calls, they most certainly will make you wait MONTHS to install the system and even with that, they would probably do a TERRIBLE job like the previous reviews said. read more

This company is very friendly. Eric was very helpful in showing me everything I need to know to maintain my system. Very satisfied with their service. read more

I requested a quote from Costco's water treatment services to help deal with our San Antonio hard water. The salesman Richard was courteous, knowlegeable and very friendly. The quote and the warranty seemed very appropriate (our house was not plumbed for a water softener), so we decided to go ahead (can't go wrong with a costco vendor)! What a nice surprise. On the day of installation Cesar and Anthony arrived on time and again were very courteous. They proceded to cut sheetrock, dig under the driveway and had PVC pipes everywhere. Our family was very concerned with the mess. By the time this crew was done, they had installed our water softener, cleaned up the mess, repaired the sheetrock and left us very excited with great tasting water and the prospect of soft water extending the life of our appliances. Thank you Oasis Water solutions, i definitely and highly recommend your company. read more

We purchased a whole new system. Oasis did a great job. Quick, good pricing and now we have baby formula quality water throughout our entire house. read more

I shopped around and compared 4 water softener companies. Oasis Water Solutions came out on top with the best price for the quality. Sales Rep- Jesse was great at letting me take the lead. I had heard the sales pitch 3 times already and was not interested in watching the demonstration for a 4th time. Jesse was very understanding, and actually asked me what I was looking for. He actually had a conversation with me. It was really refreshing and he was able to address all my concerns. He answered all my questions and followed through on all promises. Installation- Installation day was set for 2wks out from when I signed the contract. It was tough to wait that long for my new product, but worth it. The installation team was so nice. Again, they answered all my questions and I didn't feel rushed. They also came up with a really creative plan for install. My house was not pre-plumbed, but that was no issue for them. Technician- I had a technician come out to ensure everything was working properly (trying to take advantage of the first year with $0 cost for visits). Again, the guy was really nice, answered all my questions (I ask a lot of questions), and didn't feel like he was rushing. Water Quality- I am extremely happy with the quality of the water. I got the ECC Refiner and RO system. I can smell, hear, taste, feel, and see the difference in the water. No more chlorine smell. No more clanking sounds when the washer/dishwasher are running since the hardness (aka tiny minerals) are no longer present to bounce around. The water tastes clean, with a tiny bit of sweetness. The water feels smooth to the touch. I can see the difference on my black granite composite sink (bad idea for Texas, but not if you have this water softener). After 1 week prior to the softener, my black sink was grey. After the water softener, there was a tiny bit of build up, but I was assured this was from the build up in my pipes because the house never had a softener before. Now, sometime later, there is 0 build up. My clothes feel softer, reduction in my acne, and I am drinking more water (without having to use plastic bottles). I highly recommend Oasis Water Solutions. Best quality for the price. read more

I called Oasis because to try to buy some parts (rubber gaskets/O-rings) to fix my salt tank from overfilling with water on my two unit Eco-Water Polisher. I was told that they didn't stock parts, and that they could get a technician out to do a "Service Call" for only $99 and that at that time they'd be able to get me the parts. So, I scheduled the "Service Call" for my Eco-Water ERR 3502R30 that was supposed to have "Lifetime Warranty". The technician showed up, long story short, it was going to cost me $900 to replace the valve housing and associated rebuilding gaskets. Eco-Water is proprietary and you can only buy parts from them. I decided to pass and go with Simple Water Solutions bought a new system for ONLY $1,500!!! Delivered & Installed. Non-Proprietary System, and you can buy parts on-line! read more

I am very happy with the level of service i received today. I have a water softener that I inherited from my home's previous owner and it hadn't been serviced in 3 years! Eric, the Oasis technician that did the work, was very professional and walked me through everything he was doing, what needed to be done, why and how much. He was respectful of my home and family by using the proper PPE during this pandemic which i appreciate very much. I would recommend this service from this company and especially this technician. -Patrick Egan read more

I recently had my water softener serviced and about 9 months later started having problems with it again. I reached out to Oasis and was contacted immediately.

They were on time and extremely knowledgeable about the system and answered all questions my wife and I had about the system. Thank you to Phillip for taking care of my home. read more

We have been very satisfied with our water softener and RO filtering system since it was installed three weeks ago! We had a very pleasant experience with Caleb who came and made a very professional and convincing pitch of the Eco Water System!

But thanks to Caleb, we were convinced that the Eco Water system was the right choice. The installation also went very smoothly with no issues. read more
