06Suffolk plumbing FAQ
My drains are slow everywhere. Is it a clog or my cesspool?
In homes without sewer service, slow drains everywhere often mean the cesspool or septic system is full or failing. That's a different service than drain cleaning. Tell us what system you have when you call.
How do I protect a seasonal home from frozen pipes?
Keep heat on or have the plumbing winterized: water shut off, lines drained and fixtures protected.
