Sewer gas entering your home without a visible overflow typically comes from one of three sources: a dry P-trap in a rarely used drain (the water seal evaporates and lets gas through - fix by running the faucet for 30 seconds), a cracked or improperly sealed wax ring at a toilet base, or a venting problem in the drain system causing negative pressure. In older homes, cracked sewer line joints can also let gas escape underground before the pipe fully fails. The smell is not just unpleasant - hydrogen sulfide is harmful at elevated concentrations. We can identify the source quickly and give you a clear answer before it becomes a health or structural issue.

Recurring clogs almost always mean the root cause was never identified - the drain was cleared of the blockage, but not of the reason it keeps forming. The most common causes of recurring drain issues are tree root intrusion in the main line (roots grow back after snaking), partial pipe collapse from soil movement, improper pipe slope that allows solids to settle, or significant grease accumulation that a snake can only punch through rather than clear. A sewer camera inspection shows exactly what's happening inside your drain. Once you know the actual problem, you can fix it permanently instead of paying for snaking every few months.

Sudden whole-house pressure drops narrow to a few specific causes: your pressure reducing valve (PRV) has failed or its setting has slipped (common in homes over 10 years old), your municipal supply pressure dropped (confirm with your neighbor), your main shutoff valve is partially closed or its internal components have deteriorated, or a supply line somewhere in the home has a significant leak pulling volume out of the system. In older homes with galvanized pipes, internal corrosion can narrow the pipe bore enough to restrict flow - but this usually happens gradually, not suddenly. A sudden change almost always points to the PRV or a valve issue.

A drain snake (auger) is a rotating cable that physically breaks through or pulls out a blockage. It's effective for clearing a clog that's relatively close to the drain opening. It does not clean the pipe walls - it creates a hole through the obstruction and leaves grease, scale, and debris coating the interior. Hydro jetting uses pressurized water (up to 4,000 PSI) that scours the pipe walls completely clean, removing everything including biofilm and mineral deposits. Snaking is appropriate for a simple, first-time clog. Hydro jetting is the right choice for recurring blockages, significant grease buildup confirmed by camera, root intrusion that keeps returning, or pre-inspection preparation of a sewer line before lining.
