crack at bottom seam of sand filter tank

[mariane]

We discovered a crack in the bottom of our sand filter and have to replace the tank. It will take several days IF they are in stock.
We realize we shouldn't try to fix it - we tried several years ago when the crack was at the neck of the filter but this one being on the bottom, it sure is tempting to put a patch on the inside and limp thru until we can get a new tank.

I've considered getting a used DE filter to use in the meantime but was wondering how much work a DE filter would be during the interim before we are able to hook the pool back up. Used filter $40, DE - don't know yet how much we'd need. I can't tell by the pic on FB Market place.

Also wondering if during the interim we could hook up the pump directly to the return pipe just to keep the water circulated but not filtered. Will we blow the hard plumbed lines from too much pressure using a 3/4 hp pump? Hard lines are 1 1/2" - 2". We would have to use flexible hose to attach pump to heater intake pipe.

Why not use flex seal? Way cheaper.

A filter housing is a pressure vessel. The force exhibited at catastrophic failure can damage things and injure people. A pressure vessel should never be repaired except by authorized personnel and then fully pressure tested and certified after repair.

For a residential pool filter housing, replacement is required if compromised.

the DE filter would scare me with only 25 PSI, looks like an old one with an underpowered pump... My 1 hp would do 15 PSI and I have minimal plumbing...

You can easily connect the pump back to the pool without the filter connected while waiting for a new filter

Never try to fix a filter, it is under pressure and can explode in a way and hurt someone if it did so while your around it...

Thank you everyone. Long story short: we were given a new one for free Saturday morning and installed it right away. So thankful to the Lord for this. Working great and not enough down time for the water to turn green. We will perform a SLAM since the filter did not run for 24 hrs.
