Pitcher Pump Leather
Replacement Guide
Cup leathers + valve leathers
Two common repairs for traditional cast-iron pitcher pumps with leather components.
Allow the new leathers to set for a few hours before they will seal.
Before you start
Match the replacement
Compare the old leather, cylinder diameter, and mounting-hole size. Use the matching leather replacement for your pump. Rubber seals are incompatible with traditional leather components.
Tools and preparation
Have a screwdriver, wrenches, a clean cloth, and clean water ready. Keep dirt out of the pump during service.
A | Cup leather (plunger)
Remove the plunger
Loosen the pump-cap fastener and lift the plunger assembly out of the pump.
Replace the cup
Remove the cup holder and worn leather. Fit the matching new cup in the original orientation and secure the holder again.
Reassemble and test
Reinstall the plunger and cap. Prime with clean water and check pump operation.
B | Valve leather (base)
Open the pump base
Remove the base bolts and lift the pump body away from the base.
Replace the flat leather
Remove the valve weight and old leather. Clean the seat, fit the new leather, and reattach the weight in its original position.
Reassemble and test
Refit the body, secure the base hardware, and prime with clean water.
ImportantFasteners and valve arrangements vary by model. Verify the replacement fit and assembly for your pump.
