A STITCH IN TIME SAVES NINE .
Hi Kelvin ,
Water leakage , if not addressed , would leads to bigger headache . Today at 0.57% , next month would be at 5.7% and there after would be 57% ... and next year we might see you keeping crocodile when your pond dried up ...!!! .. Just kidding ... not that serious yet lah !!
Honestly , It's not a problem that you should sit on at the moment . Believe you can see the traces of leakage by now .. This trace/s happened to be the unfilled hole/s in the wall structure that water tunnel it's way out of the pond . Plugging these holes you see will not help , bcos water would still try to find other routes to migrate . You have to plug from where it starts .Here's what you should do together with your contractor .
1 ) Check all the water pipings that's in liason with the pond . Believe your contractors would know the whole pipe layout , even the concealed pipings . If your concealed pipings is punctuated due to other installations in the pond , you have to stop using this "line " and make do with an external lines . ( One good way to check is by diverting the water outlet from the pump straight to the main pond by running a temporary pipe from pump ( last chamber ) to main pond - for testing only ) If you have tried this and water still missing , then it's not water piping problem . This way you can still keep your concealed pipings .. , but if the water leak stops when you try this , then you are likely to forgo the conceal pipes and run external outlets .PVC pipes hardly crack , but it can be punctuated thru drillings while installing something else , maybe the stands of the shelters or even pins from holders ... etc .. etc .
2 ) If the water leak is still there after the above test , ( means not piping's fault ) , drain out the whole pond to check the water proofings .
I wondered what they use for water proofing in your pond by the way ?? I fibered-glass my pond internal by the way .
A little costly but gauranteed to last a longer time ( Few thousand dollars ) .
If you trust the waterproofing work , it's fine . Now it's time for you to go down to your emptied pond and check-out all the joints ,
piping joints or link , nothing must be left un-waterproofed or sealed . Even the libs of the drainage covers must be properly sealed with
water proofings around it . The inlets from main pond to the filter chambers . These libs have to be done same as well .
All corners and wall joints . This check apply to your filter chambers as well . Check all links and joints . To be doubly sure .
get your water-proofing guy along and double sealed the joints and libs again .
Honestly Kelvin , it should not take more than a week to rectify this problem . Worst scenario , is to fiber-glass the whole pond interior again if it's not the water-piping problem . Constructed ponds above ground level normally have leakage problem that's more visible than those ponds built below ground level . So .. don't despair ... Short term headache ... but long term enjoyment .
By the time you know how to rectify this leakage problem , you would be able to share your experience better .. Never Never treat this water loss as water change !!! Water change and flushing is totally a different thing ..
If you really really need help to sort out the water-proofing issue or spot the leakage , let me know ... I might send the whole gang of experts down to your place to trouble-shoot this problem . Not so nice for your contractor though ...
Cheers
David
