Water Filtration Tips & Tricks Discussion 1 with Tim Skerritt

FAQ: How does silt and sediment get into my plumbing system?

FAQ: Would having a plumber install a sediment filter in Danvers, MA help protect my plumbing fixtures?

Opinion: Why Danvers Residents Should Consider Sediment Filters for Their Homes

The Danvers, MA Water Department serves approximately 26,493 residents, according to the Environmental Working Group’s (EWG) Tap Water Database. With such a large service population, the municipal water distribution system includes tens of miles of underground piping—most of which is composed of ductile iron. 

According to Mike Emery, owner of EV Excavation in Gloucester, MA, ductile iron is a highly durable and reliable material, often lasting between 50 to 100 years. With over a decade of experience in excavation and street work, Mike notes that many of the ductile iron water mains in the North Shore region have already exceeded the 50-year mark. As these pipes age, the likelihood of water main breaks increases significantly. When a main breaks, dirt and debris can infiltrate the domestic water supply, posing a risk to household plumbing systems. 

Another common source of sediment intrusion is hydrant flushing. This maintenance process is designed to clear sediment and mineral buildup that can affect water pressure in the municipal system. Fire hydrants are opened to create a high-velocity flow, effectively scouring the interior of main lines. While effective in maintaining system performance, this same process can cause stirred-up sediment to enter residential plumbing. 

Mike also observed that there is a substantial amount of visible sediment inside the piping system. This sediment, which can range in size from 1 to 100 microns, can cause damage to a variety of plumbing fixtures over time. 

Installing a sediment filter is a simple yet effective solution to this issue. I typically install 5-micron filters, which significantly reduce the amount of debris that can affect your home’s plumbing. In my experience, the components most frequently affected by sediment include toilet fill valves, faucet and shower cartridges, shower heads, and aerators. Repairs or replacements for these items typically range from $320 to $2,200. 

Water heaters are also vulnerable. In tank-style heaters, sediment tends to accumulate at the bottom, eventually causing leaks. In tankless systems, sediment can mix with scale inside the heating coil, leading to blockages and failure. Repair or replacement for water heaters can range anywhere from $500 to $7,500, depending on the severity of the issue.

Given the age of our infrastructure and the recurring maintenance activities like hydrant flushing, investing in a quality sediment filter is a smart preventative measure. It’s a small investment that can save you thousands in plumbing repairs down the line.
