A cleanout is an access point within the plumbing waste system that allows the system to be cleaned out (snaked) in the event that a pipe becomes clogged with debris.
Both models essentially serve the same purpose to provide an access point within a plumbing waste system to clean out a drain line. The Z1440 cleanout ferrule is simply the most basic type of cleanout available. This product is a basic body with plug, and has a flange collar for attaching a waterproofing membrane, and no height adjustability found on other Zurn cleanouts such as the Z1400-BZ or Z1400-K.
Load ratings are established by criteria set within the ASME Standard A112.6.3, the standard for Floor and Trench Drains.
Safe Live Load Rating: (actual failure load divided by 2)
Light Duty: under 2,000 lbs
Medium Duty: between 2,000 & 4,999 lbs
Heavy Duty: between 5,000 & 7,499 lbs
Extra Heavy Duty: between 7,500 and 10,000 lbs
Special Duty: over 10,000 lbs
Isolation deck drains are used in applications where there are two independent concrete pours separated by a layer of insulation and the concrete slabs may be subject to expansion and contraction as a result of varying temperatures and natural structural movement.
Grease interceptors our designed to remove FOG (Fats, Oils, and Greases from food/cooking) from a water system. Oil interceptors are designed to remove and recover automotive oils.
How is a grease interceptor sized?
Grease interceptors such as the Zurn Z1170 series can be sized by either calculating the volume or flow rates of all fixtures draining into the interceptor. A spreadsheet designed to help with these calculations can be found at www.zurn.com

Flapper type backwater valves such as the Zurn Z1090 and Z1095 prevent backflow without any action on the part of the end user. Backwards flowing water closes the flapper against a gasketed sealing seat. Gate type backwater valves such as the Z1088 has a flapper at one end which functions the same as the Z1090 and Z1095, but also have a gate valve at the other end that must be manually opened and closed when needed. This acts as additional protection against backflow in applications where a 100% seal against backflow is a necessary imperative. Both types of backwater valves should be opened and inspected routinely to inspect for debris that would hinder proper operation.
Trap primers are plumbing devices designed to add water to traps to form a “trap seal” to prevent sewer gases from entering into the building. Electronic trap primers such as the Zurn Z1020 are typically stand alone units which are programmed to periodically dispense a set amount of water to multiple floor drains or other plumbing fixtures. The Zurn Z1021 trap primer acts as a traditional P-trap to a lavatory outlet piping but features an integral trap primer which diverts a small amount of water from the trap to feed another trap downstream. Other available Zurn trap primer include the Z1022 Sani-Guard Automatic Trap Primer, and the Z1023 Trap Primer Connection Adapter which can connect onto no-hub or threaded outlet floor drains.
Zurn currently has linear trench drain systems available in High Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), Aluminum, Stainless Steel, Fiberglass, and Vinylester. Which trench is best for a specific application depends on several factors including what environment it is going in, what loading it must withstand, what temperatures will the system be subjected to, what chemicals or substances will be entering the trench, and how much water must the trench handle. Additional information can be provided by Zurn Engineering.
