All went well with the installation of our sliding doors, until it rained. Then copious amounts of water leaked into the tracks. We highlighted this to the builder who stated that it shouldn't do that. He got the supplier out who also stated it shouldn't do that and he'd get back onto Origin. Origin's response was "it's got nothing to do with us". We took photographs and submitted them to Origin, via the supplier, and again Origin said "we can see the weep holes so there is no issue". Now, we know the weep holes work as our builder has cleaned them out and demonstrated them working but the design of the tracks means there is a large build up of water until, eventually, it drains. Even then it only partially drains. If you buy an Origin product be prepared for them to deny responsibility for any issues with their product and be prepared to be drying out the tracks every time it rains. The tracks that they supplied do have weep holes in them but they supplied them with wool pile covering some of the weep holes. Our diagram of track drainage holes shows what I mean. Point a) shows the track weep holes, as supplied, with the drainage holes covered by the wool pile. This minimises the availability of drainage but movement to an installation like point b) would increase drainage and prevent build up of water in the tracks and have more drainage available before and after the wool pile. I'm no door designer but even I can see the drainage design faults that Origin deny. We'd also like to see Origin actually looking properly at the evidence we have provided them with, showing the pool of water that sits in the tracks of the sliding doors, bought from them, and offering a solution.
