Pump lids are designed to seal tightly under pressure, but over time heat, pressure, and O-ring compression can make them extremely difficult to remove by hand. Forcing a stuck pump lid with improvised tools often results in cracked lids, damaged pump housings, or personal injury. The CMP Pump Lid Wrench (25300-100-000) is designed to safely and effectively remove tight pump lids without damaging the pump or lid assembly.

This wrench is engineered to match the shape and locking tabs of CMP pump lids, allowing even pressure to be applied around the lid instead of stressing one point. That even engagement reduces the risk of lid warping or cracking and makes routine pump basket cleaning faster and safer.

This is a purpose-built pool equipment tool—not a generic strap wrench or plumbing substitute.

Why Using the Correct Pump Lid Tool Matters

Pump lids are a critical sealing component in the circulation system. They must remain airtight to maintain prime and proper flow. When lids are damaged during removal, air leaks can develop that lead to loss of prime, cavitation, reduced circulation, and increased pump wear.

The CMP pump lid wrench allows lids to be removed and reinstalled correctly, helping protect the lid, O-ring, and pump housing. Using the correct tool also prevents overtightening during reinstallation, which is a common cause of future lid removal problems.

Designed for CMP and Compatible Pump Lids

This wrench is molded to fit CMP pump lids and select compatible pump models that use the same lid profile. The form-fitting design ensures solid contact with the lid tabs, providing controlled torque without slipping.

Because it is designed specifically for pool pump lids, it delivers better leverage and control than universal tools that are not shaped for pump components.

Built for Repeated Service Use

The CMP Pump Lid Wrench is constructed from durable materials intended for repeated use in pool equipment environments. It holds up to frequent handling, exposure to water, and outdoor conditions commonly found at equipment pads.

For service professionals, it reduces service time and prevents avoidable part damage. For homeowners, it makes routine basket cleaning and maintenance easier and safer.

When to Use the CMP Pump Lid Wrench

This pump lid wrench is recommended when:

• A CMP pump lid is difficult or impossible to remove by hand

• Performing routine pump basket cleaning or inspection

• Replacing or lubricating a pump lid O-ring

• Preventing damage from prying or hammering methods

• Working on CMP or compatible pumps with tight-fitting lids

Using the proper tool helps extend the life of both the pump lid and the pump itself.

Practical Tool for Pool Owners and Service Professionals

For pool owners, this wrench eliminates the frustration of stuck pump lids and reduces the risk of breaking expensive components. For service professionals, it is an essential tool that improves efficiency and protects customer equipment during routine service calls.

Proper lid removal and installation is a small step that makes a significant difference in long-term pump reliability.
