I am relatively new to this field.
And maintenance of pump specially in suction is not a big problem in my analysis since as per observation in my last project(Company standard) different type of strainer installation are selected for each type of pump assembly.. Saying for example a temporary strainer is only for one line pump and Y-type, bucket and etc are for multiple pump.

I think this problem is covered by Piping Designer. IMO when you remove the whole assembly of strainer then you just have to shut down the line or install maintenance support also i would like to point-out on how would you remove your bolting when you have those reactions....

Regards!
