I'm posting this a little behind, since we've already started work... This is our lovely new pool, as it was when we moved into the house. We got a man round to have a look, bought some new pipes to connect properly up to the swimming pool filter and pump in the basement of the house. The decking was a little bouncy but we decided to give it a go.
Removing the cover, we found seriously black water (looks like the filter hasn't been connected for several years). After several days of intensive filtering and scrubbing with a long swimming pool pole thing, it was almost looking good - we could see the bottom.
Then, just after dinner one night, I got a phone call from the neighbour behind us (the first time we met actually), who was wondering why his entire patio and much of his garden was under water...
The pool now looked like this, the liner having burst.
This was a little disappointing, because the hope was to at least test the pool before deciding whether to clean it up properly. Instead, we've now decided to get rid of it completely and replace it with a bigger garden!
