Camco Mfg 40226 Tst Holding Tank Chemical 32 Oz

Product Description

The CAMCO MFG 40226 is a 32 oz liquid holding tank chemical treatment designed to control odors and maintain sensor function in RV and portable waste holding tanks. The original TST formula requires only 4 oz to treat a full 40-gallon tank, making each bottle capable of treating up to eight full tank cycles. It is effective in any season and is safe for use with all septic systems. This product is used by RV technicians, service professionals, and knowledgeable DIYers who maintain portable sanitation equipment.

The 40226 is suited for residential and recreational vehicle holding tank applications. It is commonly used in RV black water and gray water tanks, portable restroom units, and similar waste containment systems. The formula lubricates tank sensors to help prevent false readings caused by residue buildup on sensor probes, a common maintenance issue in frequently used holding tanks. No specific model list is provided in the product data, but this treatment is compatible with standard holding tank configurations that accept liquid chemical additives.
