Hayward pump keeps leaking

[mas985]

Correct me if I am wrong but I read that the mechanical ceramic seal is failing and not any gasket or o-ring or did I misread the post.

If it is a ceramic seal, besides an incorrect installation, another possibility is that the motor shaft or impeller seat is slightly bent so the seal surfaces are not perfectly aligned. This would damage a seal in no time at all. Does the motor seem to vibrate more than it should?

Welcome to The Forum!

I also thought about a bad shaft, but you say it's a whole new pump. (however, here we need to get a little more technical - was the pump housing that was replaced or the pump housing and motor?) If it's the original motor still, you may have a warped shaft. The other thing that comes to mind is that all the seal assemblies were installed backwards - if the original 'pro' installed it backwards, anyone who went to replace it would have put it in oriented the same way.

What would help us all clarify this issue is to see pictures of the seal assembly and seal plate, from next time you break the thing open to replace it.

While this is certainly a 'head scratcher', it is probably a quickly fixed issue, once we can figure out what's causing the problem. The more info we have, the sooner we'll be able to identify and help you correct this.

HI Guys
Thank you for all your info I am going to check all those thing out,I had thought but the bent shaft but the new pumps I got were completely new, wet basket and all so that kind of ruled that out.What is Trichlor I use chlorine . The new pumps I got that leaked after 1 week were ru
n 24/7 ,so not shut down and restarts,could the vibration from the pump on the wood floor of the pumps house cause the blots to losen?what is the correct torque to bolt motor to the wet basket.
Thanks

Tri-Chlor is the standard 3" tabs that people put in automatic chlorinators or floaters, sold in every pool store.

Tri-Chlor adds chlorine, but also adds acid and stabilizer to your water. Sometimes people put the tab in the skimmer, which CAN be a problem when the pump is off as the erosion continues and concentrates chlorine in the lines into the filter or in the filter itself. But I don't believe it is USUALLY a problem.
