There are two major ways to evaluate septic systems; a dye test and a PA Septage Management Association (PSMA) protocol septic inspection.
A dye test consists of simply flushing dye down a toilet, running water, then looking for the dye to show up in the yard.
On the other hand, a PSMA protocol septic inspection involves finding the septic tank and drain field, probing the drain field, then opening and visually examining the tank.
PSMA protocol requires that the septic tank be pumped during the septic inspection. This cost is paid by the seller in most real estate agreements.
A dye test is practically worthless unless there are very severe problems, while the PSMA inspection will uncover minor, major, and potential problems. Many inspectors only use the dye test.
A bad septic system could cost you $10,000 or more to fix. Don't be fooled by a simple dye test. Insist on a septic inspection performed in accordance to PSMA standards... it's the only septic test that HomePro uses!
