"🚨 Avoid Len the Plumber – Negligent & Unsafe! 🚨 I hired Len the Plumber to install a brand-new water heater, but it failed after two weeks. They promised quick service but left us without hot water for days. Worse, the first technician concealed a serious fire hazard—the heater’s electrical components had actually caught FIRE and burned! A second technician finally admitted the fire risk, meaning my family could have been in grave danger. This is pure negligence and completely unacceptable. They replaced the heater but only after multiple delays, zero accountability, and putting our safety at risk. 🚫 DO NOT trust this company with your home’s safety! 🚫"

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"The repair work was well done. I had no idea it would take 2 people. The first quote was for a lower price but then they did not have the parts so I said OK to the more expensive option. But then they were not able to do the more expensive option so they went and got the part for the lower price option. But ultimately they charged me for the higher price option. I have called three days in a row and have not been able to resolve the price discrepancy."

FAQs for water treatment & purification system installation and replacement projects in Washington DC, DC

A whole-house water filtration system is ideal if you want all the water in your home to be filtered, improving water quality and protecting your plumbing. This system can enhance your home's value. If you only need filtered water for drinking or cooking, a point-of-use filter might be a suitable alternative. Each filtration option is designed to remove specific contaminants.

Maintaining your whole‑house water filtration system is essential for uninterrupted performance and clean water. The annual expense, which ranges between $50 and $300, covers filter replacements, complete system inspections, and any required repair work. Regular maintenance keeps the system operating at peak efficiency and guarantees the highest water quality for every home use.

Installing a whole‑house water filtration system is a streamlined process that a professional can complete in one day. Multistage systems require additional time to secure proper plumbing connections and calibrate the system accurately. In contrast, point‑of‑use filters are installed within a few hours, ensuring efficient and precise integration in your home.

Most whole-house filtration systems last 10 to 20 years with proper care. Reverse osmosis units typically serve 10 to 15 years, while water distillers can exceed two decades. Lifespan depends on build quality, water chemistry, and whether filters, lamps, or membranes are changed on schedule. Regular professional inspections help you catch minor issues before they shorten the system’s life. Budget for planned component replacements to reach the upper end of that range.

Fast clogging usually points to high sediment levels, heavy water use, or both. When more dirt and minerals flow through the system, filters load up sooner and performance drops. Schedule a water test to confirm what’s in your supply, add a sediment pre-filter if needed, and follow the manufacturer’s replacement timeline to keep water pressure and quality where they belong.
