@williamsglyn1 In the update of ToggleIt! mod is a new feature that you cannot see water pipes. I guess this is the mod you are looking for. There is a number of notes have been announced in its comment section, you can follow it.

Hard to say for me, as I haven’t done any water pipes in years. I always use the “No need for water pipes” mod.

There is a MOD on here that is hiding my water pipes so i cant see where there are to connect them up? Its not 'No need for water pipes' mod as i haven't subed to that. iv been going through them for 2 hours now and cant find it? please help.

@StayHungryStayFoolish: thanks!
I made this mostly for myself, to keep track of which mods I use and the quirks of some of them. But then I thought it might be useful for others as well.

This is a unique list, made "once upon a time" and the author is still around it keeping it updated. Thank you, I appreciate your tips and notes, it is very helpful.

I've removed the notes. Thanks for the update on Building Usage :-)

Please remove the note about Building Usage not working due to a mod conflict. The conflict has been fixed.

Please remove Building Usage from the list of mods that break the editor. I cannot duplicate the editor problem that was reported by one commenter.
