Its to do with the air over the milk line ,its not as if that air is entering the line during milking ,because we all know it cant as its being sucked away , but stinky vacuum line will sit over the milk line at atmospheric presuure when the pumps off ,so thereby letting foulness into the pipework even though its all not working !!
Its never really a massive problem ,but every little helps !!

Just spent 2 hours inside silo scrubbing what looked like little patches of rust off the roof of the tank, leaking O ring bottom of the pump presumably letting air in during the wash meant the top spray ball wasn’t full or spinning properly?!? would a slightly leaking O ring effect pump output that much? Spray ball spins fine and wasn’t blocked at all.

yes, our little bit of growth, was very hard to see, hardly anything, but peed us about for long enough ! Looked totally not the cause, but, stopped all our extra cleaning, bit by bit, bacto still down, that's the proof(fingers crossed).
Have you got an air blast, or a slugger that builds water up in a pipe before sending it down with the air blast?

yes, but a circular milk line, so surge was 'split', fine when tested each end, but not washing the top, mid line, one side ! Altered now, one big surge going round. the next thing, will be to reconnect another 4 units, as we cut back,from 24/24 to 16/16, in our quest for the fault !

we did loads of testing, some with NML and some with 'other lab' the 'other' assured us, there's was right, NML's was wrong, others told us, that the 'other' was much more precise than NML, suffice to say, NML results didn't vary, and were correct, at the 'finale', possibly might have found the problem quicker, but, don't know.

Looks like we had when we were on autosamplers. All the farms on the tanker round had the same problem. Change back to manual sampling and good bactoscans result!

Have you Taken your tap apart on your tank we had an issue there.

would it jump around like it is if it was the tap? Would think it would be permanently high if it was?Did a double sample other day after the 1300 and tanker drip sample and manual sample were within one of each other, 22/23. Got to take a sample to the buyers QC lab tomorrow morning before collection.

we have just had an 86, just the day we put the waikatos in for recording !
We had similar problem, Tank washer was not sucking up chemical, blew air line through the intake pipe an it blew off where it goes into the tank, stripped it down and the end of the pipe was all crystallised so the chemical could not get through !!

That is obviously just wrong, ignore it other than telling your milk buyer that the milk testing is bullshite!

Found the issue
inside a air solenoid diverter valve that switches to the buffer tank was full of crap inside the air bit causing it to stick and was occasionally letting milk into the buffer tank when it shouldn’t have been resulting in 40-50 litres of milk sitting at ambient temperature for 2 days and then mixing with diverted milk when the tank was washed.
Checked the buffer tank 3 times last few weeks but can’t have been doing it then. Had to throw milk away this morning as had to have sample checked before dairy would collect milk and it tested stupid high.
Bypassed buffer tank and valves etc for a few days, fingers crossed.

Glad you found it. Leave no stone un-turned. Can hide in the most obscure places.

Well done for finding. So frustrating when you can't get to the bottom of it.
