Check if the distance between the thread hole and the wall surface is sufficient; it is recommended to enlarge the hole and then re-tap it in order to thicken the screw. If there is no distance, try drilling deeper and use a longer bolt. If that doesn’t work, check the bolt spacing and consider drilling new sockets and threading them to provide fixation. If it doesn’t work anymore, it has to be discarded. P suggests including a panoramic view when sharing the footage – it’s better to have more comprehensive content, as too limited a view makes it difficult to discuss things.
You might as well ask the pump manufacturer; having it repaired at the factory is a more reliable option.
Repair using polymer repair materials
Reprocess after surfacing! It’s better to get a new one, made of stainless steel!
