Hi-Temp Self-Sealing Unions
I have a Pentair Whisper Flow Pump with 2" PCV SCH 40 piping. The pump outflow connector is leaking water through the threads. Will this Union replace my faulty threaded union conector?
Hi Mario, Most likely this would work but could you post a photo of the part in question from your current pump? This will ensure we suggest the proper item. To post a photo simply click the reply link below and upload your photo.

Hi Mario, yes this fitting will replace the 2" male adapter shown in the photo with the blue glue and pipe putty. I would start by replacing that male adapter with this union. The only concern would be if you have a crack in the actual pump housing and your pump housing is leaking and not the fitting. If that is the case then you will need this Pentair Whisperflo Pump Housing but I would start off with replacing the fitting with this union and hopefully that fixes the problem. Also, use a lot of Teflon tape on the male threads of the union before installing as that will help prevent any leaking.
Does this include 1 or 2 unions? If one, does it matter if used on inlet or discharge side of pump? Thanks.
Hello- This is just one complete union and it does not matter which side of the pump it is installed on.

After several attempts at stopping the leakage at the pump housing discharge (Teflon tape, pipe joint compound) I decided to use this type of fitting. Removed old fitting, cleaned up the housing threads, lubed the new fitting with silicone lube and screwed into the pump housing. This did require some re-plumbing, but it was minor. This new fitting uses an o-ring seal to the pump housing and has proven to be leak free.
