Is the plastic ring that's inside the basket that secures the basket to the housing screwed on tight enough? What does the o-ring look like? It's possible that it's gotten old and brittle/cracked and shrunken, therefore not functional anymore? (best practice to wipe every piece of rubber washer/o-ring with silicone grease before storing and again when taking out of storage). I doubt the basket or any other part of the pump has warped. Maybe cracked, especially if any children stood on it. I noticed that the basket sort of sags when it's full of water. Over time, I suppose that could cause a crack. I have propped mine up with a chunk of wood under the basket. We've had ours for 6 years, in full sun, every day, all summer and never had a single piece of plastic on it warp. You shouldn't need to get a hold of Intex. Check your model number, and then use it to order a new o-ring from them via their website or Amazon. Honestly, I wouldn't even do that. Considering how much in short supply all pool supplies are and how long it takes to get them delivered, I would empty the pump, and put some silicone adhesive or JB Weld around that joint, give it at least 2 days to dry and set, And deal with it, making sure to turn the valves off on both sides when the pump isn't in use it until I could replace it.
