Drywall finish inspection advise needed

[Kate J.]

I am doing gut rehab and I am at the drywall finish stage. The house is old and I need to know how do I test the mud guys for the quality. I've ordered level 5 finish. I took a leveler of about 5 ft long and when I place horizontally I can see bumps of about 1/4 inch in several places. I don't see these bumps otherwise. Should I ask to correct it or this is admissible?
