Hi all, been awhile since I’ve posted here my pond is about 3 years old now but I’ve just re designed the waterfalls.. it has two feeds now, the original main one and one coming in from the side. (This new one bypasses the garbage can (filter) but still feeds into the big garden. The problem is that now the main waterfall leaks. I had never sealed it up or secured the rocks using waterfall foam but now with the rebuild I did but now it leaks. It started off pooling in new places that soon overflowed out the back.. I got that fixed by cutting and reshaping the foam but then it started coming from somewhere I can’t see. I now have a flat flagstone shelf forming the top tier or the falls i.e the outlet from the garbage can filter flows out into it I’m not sure but I’m thinking maybe some of the water is travelling back along the underside of this slab rock and finding its way Out the back (the leak is definitely out the back it’s just that the way it’s travelling I’m having trouble isolating where it’s coming from) Does this sound likely? If it is that, will making the slab tilt forward more so the water drops off faster stop it from clinging to the bottom of the slab and travelling backwards or does anyone else have a better suggestion? The top slab is foamed in place and to be honest it’s the only place that the foam really stuck a rock in place well (of course) so if I don’t have to pull it up again that would be preferable but If tilting that rock is the easiest fix I’ll do it.. any thoughts anyone? Oh, I’ll try to attach a picture of i can remember how to do it.. as you can see.. if the picture worked.. I have the main falls shut off right now.. and there is no leaking with only the side falls on. The falls emanate from in amongst the ferns on top and I just put the piece of pond liner on top to see if that stopped the leak by forcing the flow further out on the rock.. it helped a bit but there’s still a leak.. I lose enough to have my skimmer go dry about every 8 - 12 hrs.
