General Pump Check Valves Kit 1 K01 — 6 Valves & 6 O-rings, OEM repair kit for Interpump and General Pump heads

The General Pump Pump Check Valves Kit 1 K01 is a complete OEM replacement kit that includes six O-rings and six check valves to service one pump quickly and reliably.

This kit (part numbers referenced: 70-0009, 700009, EZ TP) supplies all internal sealing and valve components needed to restore check-valve function on compatible General Pump and Interpump pump heads. Manufactured in Italy to OEM specifications, the set is designed for fast in-field repairs and routine maintenance, minimizing downtime for pressure washers and industrial pump systems.

Which pumps will this Check Valves Kit fit?

This Kit 1 K01 is compatible with a broad list of General Pump and Interpump models, covering CW, T, TT, TS and W series heads. Check your pump model number against the included fit list to confirm match before purchase.

• Compatible General Pump models include CW2004, T1505EBF, TT2028GBF, TT9071GBFUI and many more listed in the product details.
• Compatible Interpump models include W101, W131, W151 and W201.
• One kit services a single pump head and contains six check valves plus six O-rings for a complete replacement.

How do these parts improve pump performance after installation?

Replacing worn check valves and O-rings restores proper sealing and unidirectional flow, which reduces leaks and recovers consistent pressure output. Fresh springs and valve plates ensure reliable seating and quicker response under pressure cycles.

• New valve seats and plate assemblies prevent backflow and pressure loss.
• Matched springs and valve guides restore correct valve timing and lift.
• OEM-quality O-rings re-establish static and dynamic seals to stop drips and cavitation.

What exactly comes in the Kit 1 K01 and why it matters?

The kit bundles every small internal component needed for a check-valve service so technicians don’t have to source parts individually. Using the full OEM set reduces the risk of mixed or incompatible parts that can shorten pump life.

• Contains 701115 O-rings and .674 x .10 valve seats (36200366).
• Includes valve plate (36200176), spring (94737600) and valve guide (36200251).
• Complete valve assembly part number 36703201 included for direct swap.

How easy is installation and what tools are needed?

Installation requires basic mechanical skills and common hand tools; many users complete the swap during routine maintenance. Follow the pump manufacturer’s service manual for torque specs and reassembly sequence to ensure proper function.

• Typical tools: hex/allen keys, snap-ring pliers, torque wrench, screwdrivers and clean rags.
• Work on a drained, depressurized pump and replace one valve set at a time to avoid assembly errors.
• Inspect mating surfaces and clean passages before installing new components for best sealing.

Who this kit is for: Technicians, maintenance crews, and professional pressure-washer owners who need an OEM-quality, ready-to-install check valve service pack for General Pump and Interpump heads. It’s ideal when you want to restore pump sealing and flow without sourcing multiple individual parts — especially for common service intervals or to fix pressure loss and leakage issues in the field.
