We compared it against the distilled water that we had and the results were appalling. Installation was scheduled and their technician Adam Marjason completed the installation in less than 2 hrs. He is organized, knowledgeable and communicated the instructions of the RO systems to us. He answered all our questions post installation and practically went through the dos and the don'ts of the system. I will update this review in an event of any issues (if any) and how it was handled. But until then, overall we have good experience right from the start.

About three months ago, we needed to get our septic pumped out. We got a referral from one of our…read moreclose friends and they told us about..a company they used in the past, Septiclean. Extreme PSI was sub contracted by them and the staff was very personable, polite and walked us through every step. I'm kinda out in the country on the other side of Manassas by Lake Jackson so my driveway is tar and chipped and they could've just drove that big heavy truck down and broke it all up, but the driver was really cool. He left the truck at the top of the hill and they ran an extra hose line down to take care of the septic tank. They even came down and knocked on the door and let me know what they were doing. Great bunch of guys. I walked out there to check around the site they worked on couldn't even tell they were there did such a fantastic job cleaning everything up . I highly recommend both companies!

DO NOT USE - Negligent and Dangerous…read more We called Great Falls Septic (GFS) in May 2025 after our septic alarm went off. As first-time homeowners with a septic system, we relied on them for honest, professional help. Instead, we got deception, disrespect, and potential property damage. They came out, inspected the system, and said the pumps were fine but we needed the pit pumped and 3 float valves replaced. We were quoted $600 for the valves and $385 for the pump. We agreed and scheduled service for May 22. When the technician arrived, he unexpectedly demanded an extra $40 in cash for a hose that was supposedly needed to reach the bottom. He said the office gets angry if he doesn't collect money on every visit. We were confused and told him we already had a formal quote. He became rude and walked away mid-conversation. Without our knowledge or consent, the technician shut off both the septic pump and the alarm system--disabling the two systems that are meant to protect our home from sewage overflow. He then quietly left the property without saying a word. We only found out what had happened because the second company we hired confirmed it: * The pump was manually shut off. * The alarm was disabled. * Our system was left at risk of dangerous overflow. * No work had been done on the valves. When we called the office to report this, a woman named Debbie hung up on us. No explanation. No apology. Nothing. This wasn't a misunderstanding--it was willful negligence. GFS left our system compromised and our home at risk. We are filing a complaint with the Virginia Department of Health. If you value your home, your safety, and basic human decency, stay far away from GFS.

I called Great Falls and they were able to come out same day. The technician, Mauricio Apolinares immediately diagnosed the problem as a blockage between the tank and the house. While the tank was fairly full he doubted that was what was causing the back up. He dug out the inlet access port and sure enough, the baffle that empties into the tank was completely clogged. Within a couple of hours of arriving we were back in business. Very impressed with their service.

He not only performed the requested hydro jetting service to clean the pipe, but also identified the root cause of the clog (there is a "belly section"), and helped me pinpoint the section of the pipe. While he's cleaning up, he identified a sink issue which has nothing to do with the original pipe problem, he took care of that. Overall, Jon is a very friendly, professional and reliable technician, I will not need to look for another plumber, he's the best.
