Leaking pond Leaking pond, what to do Leaking ponds can cause disaster If the water level in your pond or pool is going down you may have a leak, what can you do? Unfortunately you can not ad a well known brand of car radiator sealant to your pond, it is toxic to fish. But if you could, would such a product also block the jets on any fountain pump. (unless you want to tell me otherwise)
How long has the water level been dropping? If your leak suddenly started have you just added or altered something? if so this is the first place to look for a leak. (new waterfall or water feature?) If you have added a new fountain please be aware of the JW fountain rule What to do Have you turned off all your pumps? this will prove if it is a pump or pipes leaking (check the pipes / connections are any wet) Also look around the surrounding area looking for a damp / wet patch Please also remember that in the unlikely event the sun is shinning (English humour) it may be evaporation, its not uncommon to loose 2 inches per day, in shallower pools it will be more noticeable. Also if it is a particular windy day, wind can "lift" the water reducing the over all level If you still can not find the leak, leave the pond / pool, do not refill it, wait until the water stops getting lower, mark where this point is. Is your pool made with a liner Check along water level mark (where you marked it) look for any puncture, water will leak through the smallest of holes, get a puncture repair strip, follow instructions and apply. If you can not find it remove liner and hold up to light, where you see light through the liner is your leak. re fill pool / pond. Is your pool concrete? Water will leak through the smallest crack, mark wall at water level, then empty pool, look for any obvious cracks / spits if you can not find any you are going to have to do the following all the way round, if you can find a crack then you can proceed at this point. Remove at least 8cm wide of concrete (and tiles if you have them) either side of water level (where you marked it) Clean and re cement area, allow at least 7 days to thoroughly dry. Paint with pond sealer up and down, allow to dry. Then paint with pond sealer such as G4. Retile pool / pond (if you have tiles) refill pond / pool. So long as you have followed above starting from the top, your pond / pool will not leak. This page is dedicated to Kev Jackson
