We have recently had a safety net fitted to our large garden pond (the type that also goes over swimming pools) at a cost of around 1000 pounds. We have it fenced off but took the belt and braces approach as we have DD (3.5) and DS who at 19 months is an enthusiastic climber.
Our problem is that it does not do what we expected it to do. Our expectation was that it should remain clear of the water when a reasonable weight was added. When it was initially installed DH tested it by just putting a little weight on with his hands which went straight into the water. The company came back to re tighten the net but it still deflects well into the water when any weight is added. (This time we tested with something that weighed 4kg - way less than DS - and it again deflected into the water.)
The company have e mailed (they will not talk on the phone) to refuse a refund but have offered to come and retighten it when the vegetation has died back in the winter (at a cost) or come and take it away at a time at their convenience (no refund) or we can take it up and they will refund 100 pounds if we return all the bits in good condition. I suspect they do not believe they can rectify the problem as it stands otherwise they would surely have offered to come back to sort it out now.
Comments or advice would be really welcome!
