Mark's Seal-A-Trap is a special chemically engineered liquid that preserves the "septic seal" which prevents water evaporation. Seal-A-Trap ensures the trap remains filled with liquid. Seal-A-Trap prevents sewer gasses and odors from entering through the trap and endangering the health of inhabitants. Seal-A-Trap clings to pipes and won't be flushed out of drains easily. Sold 12 per case, priced per quart.
