Q: What is a grease trap?
A: An Ashland PolyTrap grease trap (or interceptor) is a plumbing device designed to allow grease to separate from kitchen wastewater.
Q: How often should I clean my grease trap / interceptor?
A: If your Ashland grease trap is more than 60% full, then clean it.
Q: Will a garbage disposal affect a grease trap / interceptor?
A: Yes. A solids interceptor should be used between the disposal and the grease trap.
Q: Does a grease trap / interceptor prevent blockages?
A: YES! ASHLAND Grease traps / interceptors do help prevent blockages downstream of the trap / interceptor, but blockages can (and do) occur if the trap / interceptor is not cleaned often enough. A grease trap / interceptor which is not cleaned will eventually clog.
Q: Why doe�s my grease trap / interceptor back up and overflow? If I buy a new one will it back up and clog less?
A: Most commonly, grease traps / interceptors back up either because they need to be cleaned and or the grease trap / interceptor is too small for your sink which can causes an outlet to be blocked. If you buy a large unit you will need to clean it less often because it will hold more grease. All grease traps / interceptors will clog if you don't remove the grease regularly.
Q: What does the flow control do and where does it go?
A: The flow control regulates and aerates the flow of water going into the grease trap allowing the F.O.G. to separate. The flow control should be placed as close to the source of water as possible, but after the solids interceptor if present.
Q: Must the flow control fitting always be used?
A: Yes! If the flow control is not installed, the grease trap may not function properly, and greasy water could pass through to the plumbing system.
Q: Why don�t we have PDI approvals on the 4875 and APGI units?
A: PDI Standards do not apply to units larger than fifty gallons per minute.
Q: Why is grease a problem?
A: Grease is a problem because it doesn't dissolve in water. Large amounts of oil and grease in the wastewater block the pipes. These have to be cleaned more often and replaced sooner than necessary. Sometimes, the buildup of grease in the system can block sewers and flood basements. Oil and grease also affect the treatment process at the wastewater treatment plant.
