WATER SOFTENERS, WATER FILTRATION SYSTEM, REVERSE OSMOSIS

At o5, we want the safest, highest-quality water for our family, and we know you do too. o5’s approach to better water starts with testing to identify the mineral content, acidity, chlorine and other contaminants that may be present in your water. Based on what we find, we’ll offer the best solutions for getting pure, contaminant-free water for your family.

WATER SOFTENERS

Hard water is a reality throughout San Antonio and surrounding areas. With a high mineral content, hard water creates surface stains and scaly buildup on fixtures, increases wear-and-tear on appliances and causes mineral build-up in pipes and faucets. o5 Plumbing can test the level of minerals in your water and offer treatment options that work for you.

WATER FILTRATION SYSTEM

Most tap water in the U.S. has some level of contamination, from naturally occurring minerals to chlorine, lead and other chemicals. Make sure the water your family uses is clean and pure throughout your entire home with a whole-house water filtration system. o5 can help ensure clean, filtered water is available from any tap in your home for drinking, washing and bathing.

REVERSE OSMOSIS

Make your drinking water the best it can be with a reverse osmosis system. Reverse osmosis is one of the most effective and affordable ways to ensure your family has high-quality drinking water, free of contaminants. This process removes virtually all lead, asbestos, PFAS, minerals and other contaminants.

WATER HEATERS

At o5 Plumbing, we’re water heater experts. We can repair, replace or maintain any home water heating system. Our techs are certified by Navien, one of the top tankless water heater manufacturers in the world.

With a tankless on-demand water heater, you get endless hot water in your home. Because it produces hot water only when you need it, it can be a highly energy-efficient option. But for some, a conventional tank water heater is the best choice.

Your o5 Plumbing technician can assess your situation and advise you on the best water heating solution for your home and budget.

  • Tankless/On Demand

LEAK DETECTION

Some water leaks are all too obvious; others become apparent only after an unusually high water bill. Still others go undetected for too long, wasting hundreds or even thousands of gallons of water every month

With the latest diagnostic techniques, o5 Plumbing can quickly assess your situation and solve your water leak problem, whether it’s in a water supply line, an appliance or connecting hoses, in your walls or foundation. If you have a leak – or suspect you do – call the o5 Plumbing experts today.

DRAIN AND PUMP

Your sewer lines are designed to give waste a one-way trip out of your home. When that doesn’t happen, call o5 Plumbing. Whether it’s clogged drains, unpleasant odors coming from a drain, or sewage flowing back up into your sink or shower drains, it’s a problem that needs expert care immediately. The o5 Plumbing team can diagnose the problems and get your drains working the right way again.
