No worries at all. If you are looking for a quicker and better solution you may want to use one of these FOBS:
A lot of you guys probably don't realise that we do sell these FOBs:

These FOBs (foam on beer detectors) are generally used in commercial pubs to prevent an empty keg blowing foam up long beer lines and wasting a lot of beer. They often can pay themselves off in 2 weeks so they are generally a good investment for pubs or bars.
With that said these can also be used for pushing sanitiser from one keg to another and then cutting off the flow once the transfer is complete. It's probably a product you guys don't realise that this works well for this application. Would you like us to make a video on how to do this? This FOB is built for commercial application and is quite a heavy duty stainless unit. If we get a lot of request for this type of thing we could make a cheaper model for home brewers if you guys think you need a cheaper option.
This solution obviously requires no power and makes pushing sanitiser from one keg to another really fast.
