I called Sergio the owner of Best quality plumbing because a neighbor said he does good work. He helped me with my plumbing needs. He did a great job on my house. The work included a complete remodeling of my house, ,copper repipe, replacement of my fixtures, replacement of broken pipes and replacement of my sewer line which included connection to the septic tank. I found Sergio responsible and honest. He has many years of experience and he delivers what he promises. I highly recommend Best quality plumbing. Thank you Sergio.

UNDERSTAND THE ISSUE
Sewage Backing Up Into Bathroom Fixtures: When To Call A Plumber
When sewage backs up into a shower or tub, the cause may be farther downstream than that fixture. A toilet that overflows when the washing machine drains can also point to a shared restriction, because both discharges may meet along the same route. Stop running water or appliances that use the affected line. Keep people and pets away from wastewater, avoid contact, and do not keep flushing to test the system. Assessment separates a blockage from damage that needs repair.
Sewer Services Customer Reviews
I called Sergio with Best Quality plumbing at 2 PM he asked for pictures of the piping / ball valve leaking. He gave me a fair price, was at my house on 20 min and fixed the issue using Brass Ball Valve. I am an engineer and can tell you his work was really good and his charge was very reasonable. I will certainly recommend him. After, the first experience I called Sergio again for replacement of our main line. His price was 10% lower than other two I had called. I had a plumbing engineer write the specifications and showed to to Sergio and his response “ no problem “. He and his crew dug one clean out 3’ deep, removed the turf 58.5’ away dug 8’ used the best commercially available piping and fitting and finished in less than 2 days. Checked the turf, and saw a few kinks, called Sergio and Carlis showed up on Labor Day, fixed it to perfection. I can’t ask for better job done professionally. Thank you Sergio and the team. I would certainly recommend youRead review on Google

WHAT WE'LL CHECK
Your Sewage Backing Up Into Bathroom Fixtures Options
We ask which fixtures were being used, where wastewater appeared first, and whether other drains are affected. The sequence helps locate a likely branch or main sewer concern. Access and pipe condition guide whether clearing or inspection comes first. A blockage may be removable; a damaged or collapsed line requires structural work. We explain the difference before recommending a service and discuss public-system contact if the pattern extends beyond the property.
Clear A Confirmed Restriction
If the accessible line is suitable and a blockage is the cause, drain or main-line cleaning may restore passage.
Investigate And Repair Pipe Damage
If symptoms or inspection point to a crack, offset, or collapse, a separate sewer repair plan addresses the structure.

GOOD TO KNOW
Sewage Backing Up Into Bathroom Fixtures
Questions Answered.
Have a question about your plumbing? These answers cover what we’re often asked.
Why is sewage backing up into my shower?
A shower can be a low point for wastewater when a shared drain or main sewer line is restricted. Other affected fixtures help locate the likely route.
Why does my toilet overflow when the washer drains?
The washer discharge may expose a shared drain restriction. Stop using the washer and affected fixtures until the line is assessed.
Should I clean sewage from the tub myself?
Avoid contact and keep people and pets away. Do not continue using plumbing to test the line; call for guidance on the backup and cleanup needs.
Does a backup mean the sewer pipe is broken?
No. A removable blockage can cause a backup, but damage is also possible. Cleaning cannot repair a cracked or collapsed pipe.
