Check Water Supply
Is water flowing freely? Turn on your garden hose. Water should come out strong. A weak flow stops the pump. Clear any kinks in the hose. Make sure the spigot is fully open.
Inspect Inlet Filter
The filter stops debris. It protects the pump. Find the filter on the inlet. It might be a small screen. Remove the filter. Clean it thoroughly. Wash away any dirt or sand. Put the clean filter back.
Examine Unloader Valve
This valve controls pressure. It can get stuck. Locate the unloader valve. It connects to the pump. Check for blockages. Sometimes debris causes problems. Gently try to move the parts. A stuck valve stops the pump.
Verify Soap Injector
The soap injector uses suction. It draws soap into the water. Ensure the tube is not blocked. Check that the siphon tube is submerged. A blocked injector can cause issues. Clean any clogs in the tube.
Look For Leaks
Leaks reduce pump pressure. Inspect all connections. Look for water drips. Tighten any loose fittings. Check the pump seals. Damaged seals let water escape. Repair or replace leaky parts.
Check Engine/motor
The pump needs power. Is the engine running? For gas engines, check fuel. Ensure oil levels are good. For electric motors, check power. Is the cord plugged in securely? Is the circuit breaker tripped? A weak engine stops the pump.
