Houston's tap water meets federal safety standards, but meeting the standard and tasting great are two different things. Our water is treated with chlorine or chloramine for disinfection, carries seasonal sediment from surface reservoirs, and picks up taste and odor along miles of aging distribution main before it reaches your faucet. A properly chosen filtration system removes those compounds so your water is cleaner, clearer, and genuinely better to drink and cook with. Houston Flow Plumbing has installed filtration across the metro since 2010, from Bellaire townhomes to acreage homes in Tomball on well water.
There are two main approaches, and the right one depends on your goal. A whole-house (point-of-entry) filter treats every drop coming into the home, knocking out chlorine, sediment, and the chemicals that cause that swimming-pool smell, so it protects your skin, your laundry, and your fixtures. A reverse-osmosis (RO) system installs under the kitchen sink and produces highly purified drinking and cooking water by pushing it through a fine membrane that removes dissolved solids, lead, and a long list of contaminants. Many Houston homes benefit from both: whole-house carbon filtration at the main, plus an RO unit at the kitchen tap for drinking water.
We size and select systems based on your actual water and your household, not a one-size sales pitch. For city water we usually lead with carbon-based whole-house filtration; for well water in the outer suburbs we test first and may add sediment pre-filtration or treatment for iron and sulfur smell. We install cleanly at the main line or under the sink, set up the drain and connections to code, and pull permits where your municipality requires them. We're licensed Texas Master Plumbers, so the work is done right and inspected when it needs to be.
Filtration pairs naturally with other water work. Because Houston's water is hard, many customers combine a filter with a water softener so they fix taste, odor, and scale in one project. An RO unit also ties in beautifully with new kitchen plumbing or a fridge water line, and if your supply lines are old galvanized pipe, clean filtered water deserves clean pipe, which is where repiping can come into the conversation.
Pricing is flat-rate and shown before we start. An under-sink reverse-osmosis system in the Houston area typically runs $350 to $900 installed, while a whole-house carbon filtration system generally runs $1,000 to $3,500 depending on capacity and any pre-treatment needed.
