Does anyone have any tips on how to fix leaky feeders that didn't used to leak but now do? For the first few months the feeders work fine, but after some time they start to drip ( even though they've been cleaned etc) I can't figure out what the difference is between when it worked properly and now,,, what causes it to drip and how to fix it?
I think it will depend on the type of feeder you have. Some may leak if they are not level. If they are the kind that have corks in them, the cork may have dried out and is not getting a good seal. Maybe you have a hair line fracture in the plastic somewhere you can't see. This is just a few ideas to look for.
Most feeders have air and sugar solution in them (last I checked)! During the day the air expands and forces the solution out. In the evening the opposite occurs, air is drawn in. No one has yet solved this law thermo dynamics. In other words, some dripping is normal. There is a solution to the problem..... Have lots of hummers feeding so they drink at the rate that the air expands!!! Of course there are some feeders that may have a defect (usually an air leak), usually this is fairly easy to detect. Just hang the feeder over a sink inside where air temp is constant and see if it still leaks; without the effect of normal air expansion/ contraction. Joe M. Lakeland
Forgot to mention: during the winter with a lesser degree of temperature variations, its not a big problem. And this might explain why it was not noticable earlier in the year but now with higher temps its much more pronounced! Joe M. Lakeland, FL
