No! It is a good idea! Splokes has a great idea. Many pumps you purchase come with a union on them. That makes them much easier to work with. You spill less water servicing them too.

And yes. Around here we don't call it: "Rector seal":grinyes:

I cannot see how gluing (cement) my threaded fitting into the pump female housing is a good idea long-term. I will have permanently affixed the two. What if I need to switch out again someday?
 
Use a minimum of 3 wraps of Teflon tape and I would go 4 or 5 wraps and you should get a very good seal... Don't forget to wrap in the proper direction, wrap so that the tape tightens with the turn of the fitting - clockwise! DO NOT GLUE! you'll be sorry.
 
You just end up replacing a few extra fittings with the pump.

What if the pump is not the problem?

I appreciate the advice, but I think I 'll stick with the more conservative painstaking frustrating approach of re-taping and re-tigtening I've been doing for a bit longer.

Perhaps, down the road, I'll try silicone on the threads instead of cement. It should be much less permanent.

Thanks again for the help.
 
5 or six wraps of tape may be needed and then hand tighten plus 1/4 turn should do the trick. If you silicon you'll need to let that set up for 24 hours before getting it wet. Good luck and you'll get it.
 
Got a picture of the offender?

This may be the problem - me not knowing exactly what you are speaking of, because having a union permanently affixed to a pump is zero issue and having two affixed to a pump is even less! And since you seem to think it is I bet we're thinking of different things.


Also on your Teflon tape. You should not use more than 3 wraps. Teflon is one of the few materials that cold flow. If you end up with a bunch of wraps sealing a leak, over time, you can end up with the Teflon getting out of the way,(cold flowing), and the leak returning. That's why Teflon is not used as a leak-stop. Its true roll is to allow later disassembly with minimum galling.

My old mechanical engineering boss used to rage at us for thinking anything we added to a threaded connection had something to do with sealing the connection. The threads themselves are designed to interfere and mate such that there is no viable path for the media to escape.

Also I hope you aren't unscrewing and replacing the tape over and over each time you go tighter... You should just tighten and watch for a few minutes. Still drip? Tighten further. Step and repeat until the leak stops. Continued disassembly and reassembly will result in galled threads and worse leaking.
 
I am happy, moreover, I am relieved to inform you the leak has stopped the fitting has been bone dry for over 12 hours. :thm:

Thanks to all for your help and opinions. Ultimately, it took me to remove the hardware, re-tape, apply rectorseal, and refasten + 1 full trun beyond hand tighten. <see pics>
