Sewer Repair
Cracked clay and cast iron sewer lines, roots and repeat backups under century-old homes.
Better-tasting drinking water, peace of mind in a century-old home or protection for a new water heater. We test your water and recommend a filtration system that fits your home and your goals. Our office is on Ravenswood Avenue.

We install:
Filtered water at every tap and shower.
For drinking and cooking.
Very clean water from a dedicated faucet.
Less scale on fixtures and in heaters.
We test what affects your plumbing and your taste, like hardness, chlorine and sediment, and explain the results plainly.
Chicago's Lake Michigan water is treated and tested by the city. The pipes inside a century-old home are a separate question. For health-related testing, a state-certified lab can run a full panel, and we'll point you to one.
The city treats the water. What happens inside an older home depends on its pipes.
Old galvanized pipe can affect taste, color and pressure.
A whole-house filter treats everything. An under-sink filter treats drinking water.
Filtration helps keep new faucets and appliances clean.
Test first, then recommend.
At your tap.
Whole-house to under-sink.
Approved first.

Chicago treats and tests its Lake Michigan water before it reaches your street. Inside an older Ravenswood home, the water then passes through decades-old pipe and fixtures. A filter at the kitchen sink is the simplest way to improve drinking water. A whole-house filter treats everything. If you're seeing rusty water or low pressure, the pipe itself may need attention, and we'll tell you if a filter is masking a bigger problem.

"Anthony was our technician to take out our old water heater and install a new one as well as install new inside parts to two of our toilets. He was very professional, courteous, respectful of our home, and very pleasant with whom to deal. We were very happy to have had Anthony as our plumber."
"Couldn’t recommend J. Blanton enough. Thomas came to replace a tankless heater and was so knowledgeable and friendly. We will be using them for all plumbing services moving forward!"
"Once again J Blanton got us scheduled quickly. Their technicians were efficient and left the workspace immaculate."
