Well, this mod is for you. This mod makes water purifiers Invulnerable. Or... simply less vulnerable if that's what you prefer.
Comes in 4 flavors, plus Wasteland Workshop versions for each. Affects both Industrial and regular water purifiers (plus powered water pumps in the WW versions). Pick one upon install, and disable/delete the others.
Invulnerable
Exactly what it says on the tin. Removes the damage records from water purifiers.
ALT (Insane Health)
If you're having problems with the Invulnerable version, run this one instead. This leaves the destruction records in, but sets their health to 99999 (instead of the default 50), making it almost impossible to destroy them.
Less Destructable
For those who still want a little bit of realism regarding water purifier destructibility but think that 50 health is a little ridiculous. Gives water purifiers 5000 health instead of the default 50.
Somewhat Less Destructable
Same as the above, but only grants them 500 health instead of 5000. For a more "reasonable" gameplay.
Compatiblity:
Not compatible with anything that modifies vanilla water purifiers.
