We do it during a service visit, usually when an inspection shows the filter is loaded with buildup or restricting flow. The new cartridge goes into the tee or housing you already have.
When the filter needs replacing
A cartridge packed with solids restricts what leaves the tank. We usually find that when we open the tank for an inspection or a service visit. If your system already has an outlet tee or filter housing that takes a replacement cartridge, this is a quick swap and not a bigger repair.
Many projects also need septic baffle repair or replacement. Shopping for septic tank pumping in Pueblo? Our home page has more.

How we scope the job
We open the tank access, look at the existing outlet tee or housing, and confirm the cartridge size so the new one fits it. We bring a replacement cartridge sized for that tee or housing, so there is no second trip for parts.

How we do the replacement
We pull the old cartridge and install the new one in the manufacturer-specified orientation, with its arrow toward the outlet pipe where one is marked. We seat it fully in the tee or housing, then replace and secure the tank cover. The only part we install is the cartridge itself.
What it costs
Replacing an effluent filter cartridge runs $75 to $200 total, installed during a service visit. The main variable is the cartridge size your existing tee or housing needs. We can give you that typical range on the phone, and we confirm the exact figure once we see the tank.
Permits
Pueblo uses the 2021 International Residential Code for residential building permits. If we find something beyond a cartridge swap once the tank is open, we tell you before we start whether it involves a permit.
