if you had ball valves and unions put into your plumbing. should be as easy as shutting off all your plumbing (return and overflow) and then taking the unions off. Take old sump out, new sump in. Replace plumbing and fill water as needed. THen check for leaks.
Oh ok. I really want to get a new sump so I can use up all of the space I have in my stand. I'm gonna b getting sum unions Also so I can do the plumbing right when I get it. If I need more info I'll ask for help.
Thanks
