This winter same leaking/dripping in the back room ceiling. I have finally figured out (by all the icicles off my gutter) that my gutters have frozen up and the water off the roof is backing up beyond the flashing. The pop-up was covered in snow and frozen shut.
I came across this site while searching for a solution to this problem. I don't know if they put in gravel under the popup - that will be the first thing I check in the spring.
Qwerty, you can check for gravel all you want. And there can be gravel. But the gravel won't make that pop up .....pop up!
Frozen is frozen,
Best thing you can do is get rid of the pop ups.
From what I understand, the pop ups are supposed to have a small hole to drain water into the ground if the top doesnt pop. Well if you have 2 or more 3" down spouts running into one line.....that would have to be a darn big hole to allow water from 2x3" down spouts to escape!
If you need to get your roof water away from the dwelling and patio, install a dry well.
This spring will mark 15 yrs for me doing hardscapes. And thusfar, we don't have ONE pop up under our belt......
