Mine hang low also when real warm but not that low. I gotta be careful when sitting on the throne, Depends on the water level but they sometimes skim the surface. Not a problem in my throne but on someone else’s or a strange throne I gotta hold them up a bit. Never know what kind of bugs are swimming around in there. PS, only the left one touches the water. The right one is hung 3/4” higher. I would like them closer to the same level but stretching the high one seems not to have produced the desired result. Maybe several more months of pulling my nut will do the job.
