Main slide leaks. Difficulty getting warranty action

if you had a leak in your new HOUSE and they stated they would install a small tarp over that area where the leak is, would accept that? While the slide cover is a good thing to have, installing one because they are unable(they could if they had the factory haul it back) to find to repair a defect, is not correct. LEAKS need fixed, not covered up. Doug
PS, They did not due the pressure test correctly if they could not find the source.
