Here are 2 of the 3 pumps.
In the foreground a mak4 (skimmer pump)
In the background, an LG 4 (return)
The LG had a clog in it's line when I first ran it - scared me! Made me think the pump wasn't working. Kept it running for a while and it created so much back pressure that the pipe flew off. Turns out I hadn't glued 2 connections (out of about 100) and the clog was in-between them! Water went flying up all over and after I pulled out the plug I found that the clog was made from an overusage of glue - it had created a complete seal on the pipe. Knife with a long handle, and I had cut the glue out. Resealed and we're good to go. That old LG pump has been a workhorse. loud as hell - but just keeps pumping.
