What Is a Backwater Valve and Do You Need One?
A backwater valve is a one-way device fitted to the main sewer line, usually near the cleanout. A hinged flap rests open so waste flows out normally. If the city sewer backs up and water starts moving toward your house, floats lift the flap and seal the pipe, so sewage from the public main cannot […]
Tree Roots in Your Sewer Line: What Kills Them and What Fixes It
Tree roots get into a sewer line through a crack or a loose joint that was already there. The pipe is the wettest thing in the soil, and roots find it. Chemicals kill the roots inside the pipe but not the tree and not the crack, which is why they grow back to the same […]
Cast Iron Plumbing: How to Tell If You Have It and What to Do
Cast iron plumbing is the dark grey drain and sewer pipe installed in most American homes built before roughly 1980. It does not rust from the outside in. It corrodes from the inside, along the bottom of the pipe, until the wall thins into a trough and the pipe loses its structure. The important part […]
How Much Does a Plumber Cost? Real Prices in DFW
Plumbers charge $75 to $150 per hour nationally for standard residential work, and $100 to $200 per hour for a master plumber. But most DFW companies, including ours, do not bill by the hour at all. They quote a flat price per job. That difference is why a repair that takes twenty minutes can still […]
S-Trap vs P-Trap: How to Tell Which One Is Under Your Sink
Look at the pipe under your sink. If it curves down, back up, and then drops straight down through the floor, that is an S-trap, and current plumbing code prohibits it. If it curves down, back up, and then runs sideways into the wall, that is a P-trap, and it is the only shape approved […]
Leaky Outdoor Faucet? Where It Drips Tells You How to Fix It
A leaky outdoor faucet is diagnosed by where the water comes out. Dripping from the spout with the handle closed means a worn stem washer. Water seeping around the handle when it is running means a loose packing nut, which is usually a one-minute fix. Water from the plastic cap on top means a failed […]
Sewer Line Installation Defects
Sewer line installation defects are the built-in mistakes that show up on a camera years after the trench was filled: a hard 90 at a direction change, a flat run with no fall, joints that were buried before anyone water tested them. Nuflow DFW (RMP# 46694) finds these across the Dallas-Fort Worth Metroplex on lines […]

Sewer Line Replacement vs Pipe Lining: Which One Do You Actually Need?
The choice between sewer line replacement and pipe lining is usually decided by your pipe’s condition, not your budget. Lining works when the existing pipe still holds its shape, which covers cracks, corrosion, and root intrusion. Replacement is required when the pipe has collapsed, sagged into a belly, or lost structural integrity. A camera inspection […]
