Step 1 Drainwaterpipesandheadertanks.
Step 2 Flushwater lineswith cleanwater orforced air. When cleaning the waterlines with forced air, ensure the endof the drinker line is open so that thehigh pressure air can easily force thewaterouttheendofthedrinkerline.Airpressureshouldbecloselyregulatedsothatitisnottoohigh,whichcancausedamagetothedrinkerlines.
Step 3 Scrub header tanks to remove scale andbiofilmdeposit anddraintotheexteriorofthehouse.
Step 4 Refillthetankwithfreshwaterandaddanapprovedsanitizer. The sanitizer must be approved for use with the drinkingsystemandusedatthecorrectdilutionforeffectivebiofilmremoval.

Step 6 For disinfection after depletion only, fill the header tank tonormal operating level with additional sanitizer solutionat the appropriate strength.Replace the lid and allow thedisinfectanttoremaininsidethetankfor24-72hours.
Step 7 Drain the tank anddrinker lines thoroughly and rinsewithcleanwater.
Step 8 Refillthetankwithfreshwaterpriortobirdarrival.

Interpreting results• Visual inspection is a primary tool for determining the
effectivenessofcleaninganddisinfectionoftheexteriorpartsofthedrinkingsystem.
• Regularassessmentsofwaterquality,bothatthesourceandreservoirs, are necessary for monitoring microbial load andmineralcontent.
√ Total viable bacterial count is a good quality assurancetest.ThetablebelowshowsthestandardoperatinglevelsofTVCsandspecificpathogens.
