Gulfmew Diaphragm Repair Kit for Rain Bird DRKCP/CPF-Compatible Valves — 6-Pack, Complete Diaphragms & Filters

Gulfmew Diaphragm Repair Kit is a six-piece set of replacement parts engineered to restore function to Rain Bird DRKCP/CPF-compatible irrigation valves quickly and affordably.

If a garden valve is leaking, failing to open, or showing reduced water pressure, replacing the diaphragm assembly often solves the problem without swapping the entire valve. This kit contains every small part typically needed for a full diaphragm service—rubber diaphragms, filters, screws and a spare spring—so you can complete the repair with a standard screwdriver and minimal downtime.

How does this kit match Rain Bird DRKCP/CPF and similar valves?

The Gulfmew kit is built to be compatible with Rain Bird CP, CPF, DV, DAS, ASVF and other related series that use the DRKCP/CPF-style diaphragm. Parts are sized to align with the original valve geometry so seals seat correctly and flow control returns to designed performance.

• Includes black rubber diaphragm assemblies sized for DRKCP/CPF fit.
• White diaphragm filter and solenoid filter match factory filtration points.
• Supplied screws and spring replicate the valve’s original hardware.

What parts are included and what does each part do?

The kit provides a full set of service components needed for a standard diaphragm change. Each piece addresses a common wear point so you replace everything that could be causing leaks or pressure issues in one visit.

• Black rubber diaphragm assembly – restores the primary sealing surface.
• White diaphragm filter – prevents debris from passing through the diaphragm.
• New solenoid filter – protects the solenoid and pilot parts from clogging.
• Six screws and one spare diaphragm spring – replace corroded fasteners and worn tension parts.

How difficult is installation and what tools are required?

Installation is straightforward for anyone familiar with basic irrigation valve maintenance. No specialty tools are required—only a standard or Phillips screwdriver to remove the valve bonnet and fasten the new parts.

• Remove valve bonnet with screwdriver, lift out old diaphragm and components.
• Clean the valve seat, install the new diaphragm and filters in the correct orientation.
• Refit screws and test the valve under normal water pressure to confirm proper operation.

Why choose this repair kit over replacing the whole valve?

Replacing the diaphragm assembly is a cost-conscious way to extend the life of an irrigation valve and restore reliable operation. The Gulfmew kit gives you the parts to address the most common mechanical failures, often saving time and money compared with a full valve replacement.

• Lower cost than buying a new valve while fixing leaks and operational faults.
• Complete set reduces return trips for missing parts during repair.
• Simple installation limits downtime for irrigation schedules.

Who is this for: Homeowners, landscape contractors, and maintenance pros who service Rain Bird-style irrigation systems and need a dependable, economical diaphragm replacement option. If you maintain CP, CPF, DV, DAS, or ASVF series valves and want a complete set of compatible parts to perform field repairs quickly, this Gulfmew 6-pack is designed for that purpose.
