Maintenance
It is important to keep the inside of the flush tank clean and free of dirt, debris, or glass fiber.
These can prevent the pump foot valve from sealing properly.
The SP4 solvent pump is essentially maintenance free except it will occasionally be necessary to
replace the O-ring on the pump foot valve.
