Hoping to remedy leak without draining!
One time I punched a hole clear through the return tubing that leads from the bottom pof the pond to the top to the waterfall.......sheeeeesh.....what a royal mess to dig up and find the leak. So much for yard art on a stick! I feel for you.
Al, if you can get a tube from a shop vac under the liner and force air under the liner, you should get bubbles at the site of the leak. I would guess an air compressor would work for you too.
Marcia, what a brilliant suggestion! We have a few small leaks in our pond and I just told this to my wife. What a great way to troubleshoot. ☺
Shut off your waterfalls first and see if your water level goes down (you will have to aerate your pond separate from your waterfalls). If it does not, then your problems/leaks are confined to your falls and stream. If your water level goes down after you have shut down your waterfalls, then there is a leak in your liner - the water level should drain to the level where the leak is - if you dribble drops of milk by the edge of the water and the liner and wait, you will see the milk moving towards the leak.
Husb. rubs soap on tires to check for leaks. Where leak is will bubble as air is coming out. Should work on EPDM liner I would think.
I fully understand leak problems as you probably saw on end of Merry Marys post about upside of ponding.
"just been there, done that..."
Is that the best statement of the day,lol....I think we've ALL had one glitch or another as some point! :)
