Use Low Pressure Hoses
Make sure you have a high volume, low pressure hose handy in the pit. The small garden hose types are adequate to wash teats but not much use in removing manure.
A 1½” (38mm) hose at 200L/min works nicely. Keep the pressure low (around 240 kPa) as high pressure hoses splatter the manure on walls and upset the cows.
Tips on Getting the Best Result
A fast simple shut off valve makes them easy to use. Two shorter hoses placed at either end of the pit are better than one long one. A hand scraper or scoop can help reduce the need for hosing the platform.
Pros and Cons
Saves time too. Use separate low-flow hoses to wash cows’ teats.
Issues in Making it Happen
May slow clean-up but splash crap less
Keep splashes away from cows teats as much as possible.
