Aulpq Irritrol 205 Valve Diaphragm Kit 100232 — Compatible with 205/205S/205SF/205T/205TF, stops leaks & restores flow

The Aulpq Valve Diaphragm Kit 100232 replaces worn or damaged diaphragms in Irritrol 205-series, Richdel R-204 and compatible Rainjet valves to stop leaks and restore reliable sprinkler control.

If a sprinkler zone drips, fails to open properly, or cycles inconsistently, the diaphragm inside the valve is a common culprit. The Aulpq 100232 kit provides a direct replacement part engineered to fit all Irritrol 205 models (205, 205S, 205SF, 205T, 205TF) and several Rainjet and Richdel variants. Swapping the diaphragm is a cost-effective alternative to replacing the entire valve and can be completed quickly with basic tools.

How will installing this diaphragm kit fix leaks and poor valve performance?

A torn, hardened, or deformed diaphragm no longer seals the valve seat evenly, which allows water to bypass the closed valve and causes erratic behavior. Replacing the diaphragm restores the designed seal geometry so the valve can open and close precisely.

• Replaces worn sealing edge to stop slow leaks.
• Restores proper seating to eliminate partial openings.
• Improves flow control for consistent irrigation cycles.
• Avoids premature solenoid or body damage from continuous leakage.

Is this Aulpq kit truly compatible with my Irritrol, Richdel, or Rainjet valve?

The Aulpq 100232 is manufactured to match the diaphragm dimensions and mounting profile used in the Irritrol 205 family and common Richdel/Rainjet models. It fits by design without modifying the valve body, provided your valve is one of the listed models.

• Direct fit for Irritrol 205, 205S, 205SF, 205T, 205TF models.
• Compatible with Richdel R-204 and Rainjet 204, 710A-712A, RJ711, RJ713.
• No cutting or reshaping required for standard installations.
• Check model stamping on the valve cover for verification before purchase.

What makes the Aulpq diaphragm more durable than a used original?

Aulpq uses resilient materials chosen for resistance to fatigue, chemical exposure, and temperature cycling common in outdoor irrigation systems. That results in longer service life and fewer failures between scheduled maintenance intervals.

• Constructed from durable elastomers that resist cracking and hardening.
• Engineered sealing edge to maintain contact after repeated cycles.
• Resists particulate abrasion in typical water sources.
• Designed for 2–3 years service life under normal conditions.

How difficult is installation, and what tools will I need?

Installing the diaphragm is straightforward and usually faster than replacing the entire valve. Basic hand tools and a brief shut-off of the irrigation zone are all that's required, making it a practical DIY repair.

• Remove valve cover and old diaphragm—no special tools required.
• Clean valve seat and port area before seating the new diaphragm.
• Reassemble cover and test zone for proper operation.
• Replacement typically takes 10–20 minutes per valve for a homeowner.

Who is this for: The Aulpq Valve Diaphragm Kit 100232 is aimed at homeowners, landscapers, and irrigation technicians who want an affordable, quick fix for leaking or unreliable sprinkler valves. It suits anyone maintaining Irritrol 205-series valves or the listed Richdel and Rainjet models who prefers replacing a small part over buying a new valve body. If you maintain multiple zones or manage routine irrigation upkeep, keeping a spare diaphragm on hand will reduce downtime and service calls.
