This is the third WP-100 I've purchased in the past eight years. The first one had the same problem as the second unit. The "Replacement Hose/Handle Assembly" developed a tear in the hose. This happened with the first unit after two years, and about six years later with the second unit. Also, the gasket in the base unit wears out after a couple of years, and since I couldn't find a replacement for the base unit gasket, I decided to replace the entire unit.
