Guys I had a leak on my 150 gal and it is being repaired. While the tank is at the shop, I wanted to clean up my sump and make it cleaner so I wanted to have my plumbing re-done. What I wanted to know is, I have seen some nice plumbing work done on tanks. I am not looking for anything fancy but there was a guy here in Dallas that is a plumber and charges $70 hr and he furnishes everything. I don't have any experience plumbing. I was looking to free up the extra pumps in my sump from GFO and GAC reactors and my chiller and the guy stated he could tie everything into my return pump. Anyways just wanted to know is there a science to plumbing. Would you do it yourself or would you get someone experienced Thanks for your help!
