Fix Leaking Pool Equipment with Split Union Nut. No Pipe removal Needed.

This video covers a quick fix to a leaking pool equipment union nut to a salt cell or pool pump. The union nuts on pool equipment crack and leak over time and a great fix is using a split nut. I’ll walk you through step by step. Make sure you measure both sides and the threads are correct.

Dude , you totally saved me from re piping my system due to a cracked union and no extra pipe to do a quick repair . Thank you so much . 2 days from Amazon and it's fixed ..

[@how2togo]

That's what I'm talking about. Very nice!

[@genuineci4696]

This video save me $250 that my pool tech was trying to charge me. Bought the exact one he said from Amazon and it worked perfectly. So happy. Thank you so much.

[@alexb9039]

Mind blown!!! Did not know these even exist. Thank you.

Life saver

Used this fix yesterday and probably saved a $200 service call..worked as described in this DIY video

[@vernonbrooke6997]

Thanks tried this today works like a champ. No leaks good tight fit. Thanks a Million.

[@jenniferfrost4835]

You totally saved us on this one! Exact same problem, exact same system. Googled you on Friday, had the part delivered on Sunday. Back in business 20 minutes later. TY!

[@sjd7165]

Thank you for the video! I cracked the union nut on a Sunday afternoon after cleaning the salt cell. Saw your video after a google search, ordered the part, and within 24 hours it shipped and I easily installed it. Worked like a charm!

[@kilderken7401]

This vid saved me so much time and money. I just put one of these on today. No runs, drips or errors. Easy install. I bought two extras just in case I crack the other one. Someone else recommended an oil filter wrench for final tightening. works much better than a pipe wrench or even a strap wrench. Thank you!

[@athomeonthehomestead.1394]

Thank you! Appreciate the part link in the description, too!!

[@siestakeygirl1000]

Thanks so much, this is exactly what I needed. So sweet of you to share this hack. Blessings!

[@markshute3207]

Union nuts are only hand tight and never put a jawed wrench to tighten them or loosen. If you have to loosen to take apart use a strap wrench

[@squaredpebbs6552]

Worked perfectly! Thank you for sharing.

[@pinoy0125]

Wow, a freakin' lifesaver. I was worried with how to redo the plumbing until I saw this video. I bought the last 3 available on the Amazon link provided for I know the other side will eventually leak since it is 19 years old. Plus I have a spare for future use.

[@robertwagner1079]

I have a question...You did Excellent .. However make sure you have that Hayward salt cell in the Wright direction??? The wiring Harness should be pointed to the equipment...Arrows should tell you ..

[@FixItWithMe]

I have a coupler attaching a 3 way space saver Jandy diverter valve for my skimmer/main drain that is leaking. Can I just add more PVC cement to the area?? I don’t want to cut it bc it’s such a small space (hence why they used the space saver Jandy valve). Thanks!

[@J3ffish]

Damn, I needed this two weeks ago.....ugh IHML

[@how2togo]

Well for the future

[@1speeder]

I didn't know these split nuts existed. I have the same situation, but my cracked isn't leaking - yet. Thanks for the video! Sorry about the sandwich :(

[@how2togo]

Lol, yea this thing saved me.

[@BornOnThursday]

Watching because I over tightened one, and it cracked. Hopefully I can find one that fits mine.

[@rruff20]

I did exactly what you did. Bought the exact same split nut that was the wrong size. I don't see where you list the correct Split nut... but I'm still looking around.

[@johnluff3097]

Thank you for your video. I had the same issue with a cracked union it so I ordered this from your store yesterday and just installed it. Working great and a very easy fix. Really didn’t want to get into cutting the plumbing to replace the union. Question to you, looks like it’s been a year since you posted your video. Is it still holding up fine? Thank you again for sharing your video and link to the part.

[@how2togo]

Still holding no issues.

[@siestakeygirl1000]

I ordered the one you said and it was the one that to small

[@PurpleAlleyCat]

My old hayward pump uses 4 inch threaded diameter with 3 1/2 pipe anyone know where to get one? Looked all over

[@nickybiceps5888]

Great video. What if it’s leaking similarly to yours but I can’t visibly see a crack? I’m beyond confused to be honest as to whether or not I should try replacing it or if something else I should be looking at. 15 psi right now if that matters.

[@how2togo]

That's a bit high. You should try cleaning your filter. Also, the split nut is cheap to try.

[@sherylW315]

What do you do when the nut isn’t actually the problem but the pipe flange is splitting?

[@ChristopherRoever]

Did you need to use any o-rings with the split union nut. I cracked the existing nut and have same hayward salt cell.

[@how2togo]

No

[@chrism1916]

Have similar cracked pvc union going into my Jandy pump. They unfortunately apparently make their size of union so it does not adhere to any standard split union nut that you can purchase. You have to purchase their union nut (no split version available) then cut and reinstall PVC. Not going with them when I replace this pump - making proprietary sizes is anti-consumer.

[@how2togo]

Brutal. Thanks for sharing

[@christophermadeira2967]

@how2togo I ordered the part from your Amazon store. Do I need to order an o ring for this too? I don’t think it comes with one? Please help

[@how2togo]

No, you shouldn't have to. What you ordered on the store will do it.

[@christophermadeira2967]

@@how2togo ok thank you. I hope cleaning my cell will fix it and I won’t have to buy a new one. I’ll know in a few days when the union comes and I can take off cell and clean

[@scottlandb6579]

Did the split collar hold up over time? Ever 3-4 mos you gotta service your cell. Has the split collar worked after that too?

Yes, just fine

[@d.j.williams4815]

People crank on these nuts when they should just replace the o-rings that get flattened. Use some silicone grease. Hand tight is all you need. Crank on the nuts and they'll crack

[@danaparish1644]

You NEVER use a pipe wrench or channel locks to tighten a union nut. YOU are the one who caused the crack in that union nut. “If” you need to use a wrench to loosen a union nut, you can use either a strap wrench (as suggested earlier) or you can get a set of 12” Filter Pliers (which tighten all the way around the nut evenly, without crushing down on one end).
