Re: Installing a new pump

You clearly state that the threaded connection leaks with using teflon tape. Teflon tape is not allowed in industrial construction for chemical plants, they threw it out a long time ago. The only seal for parallel threads should be a fibre ring that the pipe would bottom out onto against a step in the diameter. Your pump and pipe are probably a plastic of some kind and in that case the pipe should bottom out on a rubber ring. However, French piping and fittings are a total disaster in the area of plumbing. A parallel thread needs filling with hessian fibre and plumbing paste or better still a liquid joint setting (which goes solid after a while, but can still be unscrewed). These are all available in your brico.
If it's ice, it's nice. If it's hot, it's not.

Thanks, the Loctite 55 worked a treat. The pump is now working well with no leaks. Lots of PH - needed again. We’re currently deep cleaning the pool with the robot - later this morning we’ll restart again. It’s amazing how much dust gets in the pool even with a cover. Pool readings are now ok. Final job will then be to restart the heat pump. I might get a chance to swim before the end of the month!

Hi SW31girl,

I'm glad the Loctite 55 worked for you. I've used it for some time now, especially for parallel threads and have had good success. It's a lot quicker and less messy than hemp and paste as well.

After that success and good advice, I will order some online so I will be prepared for my next plumbing project.
Thanks for the advice Michael.
