Collapsed Waste Holding Tank - Maxum Boat Owners Club

cruz'r · 08-20-2014, 09:14 AM

Plastic waste holding tank on my 2400 SCR collapsed during pump out. Anyone knows how to put it back to its original shape without disconnecting all hoses and removing the tank, and how to avoid not to happen again. Thanks... for the help.

Probably collapsed due to a clogged vent. Did it crack? Pressurizing with air may get it back into shape.

One heck of a vacuum pressure on that pump out station! I would think that it has cracks now. Better to just replace.

Second the clogged vent hose. Can also try filling it up with water to restore shape as well.

Clear the vent line and replace the tank. It's been compromised and may leak.

You'll all be surprised, I restored the plastic waste holding tank to its original shape and no crack and not leaking. I disconnected all the hoses, removed the tank, plugged all the openings and pressurized with air through the vent port and it popped! I found the vent totally clogged that cause it to collapsed, vent is now clear and should not happen again. Thank you guys... love this forum.
