Why do I need an Inspection?
Septic tanks and absorption areas are expensive to build and replace. The average system should last for twenty years plus with proper maintenance. Some systems unfortunately only last a few years, before problems or failures occur. The reasons are many, from improper design and installation to improper maintenance, and hydraulic overloading.
Getting an inspection can help evaluate what needs to be done as well as tell in what condition your septic system is in.

 PL-122 Effluent Filter

The PL-122 was the first filter developed by Polylok. The biggest advantage of this filter is that it has an automatic shut off ball built into every filter. When the filter is removed for regular cleaning, the ball will float up and temporarily shut off the system so the effluent won’t leave the tank. To this day, no other manufacturer can make that claim. It is also rated for 1,500-3,000 GPD (Gallons Per Day) and is NSF approved.


  • Offers over 122 linear feet of 1/16th inch filter slots
  • Has a flow control ball that shuts off the flow of effluent when the filter is removed for cleanings
  • Has its own gas deflector ball which deflects solids away
  • Installs easily in new tanks, or retrofits in existing systems
  • Comes complete with its own housing; no gluing of tees or pipe
  • Rated for 1,500-3,000 GPD
  • Has a modular design allowing for increased filtration
  • Accepts 3'' and 4'' SCHD 40 and SDR 35 Pipe

The PL-122 Effluent Filter should operate efficiently for several years under normal conditions before requiring cleaning. It is recommended that the filter be cleaned every time the tank is pumped or at least every three years. If the installed filter contains an optional alarm, the owner will be notified by an alarm when the filter needs servicing. Servicing should be done by a certified septic tank pumper or installer.

Maintenance Instructions:

  1. Locate the outlet of the septic tank.
  2. Remove tank cover and pump tank if necessary.
  3. Do not use plumbing when cleaning filter.
  4. Pull PL-122 out of the housing.
  5. Hose off filter over the septic tank. Make sure all solids fall back into septic tank.
  6. Insert the filter cartridge back into the housing making sure the filter is properly aligned and completely inserted.
  7. Replace septic tank cover. PL-122 Installation: Ideal for residential and commercial waste flows from 1,500-3,000 Gallons Per Day (GPD).
