Pump Pipes Leaking after new pump installation

[rbdeli]

I recently had a plumber (not a pool expert) install a Pentair Intelliflow variable speed pump. He mostly used the same piping from my previous pump.
The vertical pipes and fittings directly above the pump gush water when the pump is first powered-up. (See Picture) Once the pump gets up to speed the water stops gushing and there is no leaking after that.

Is there a secret to getting these pipes and fittings sealed better to withstand the pressure? It seems to have something to do with the pump entering high-speed priming mode as soon as its turned on. Perhaps I need to disable priming model. Other than that, can you offer any tips on getting the pipe and fittings sealed better?

Thanks much for your help,

Rob

Since no one else answered, I'll answer my own question.

I did lots of research about plastic, threaded pipe fitting and I got as many different and contradicting answers as there are pool owners.
What finally ended up working was about 6-7 rotations of Teflon tape around the threads of the 2" male pipe fitting which is about 4 inches just above the pump discharge. Some people said this never works ALWAYS use pipe paste. Another guy said too much Teflon tape was a bad idea. Well, so much for those naysayers. The most popular methods of 6-8 wraps of Teflon stopped 100% of the leaks for me. Also, I tightened the pump discharge fitting which had only a very slight leak with a pipe wrench another quarter turn (it appears the thread on the pump go all the way down to the pump, so I was not overly concerned with harming the threads on the pump.) Also, I had a small leak on the same fitting near the sand filter. This fitting feels as though it is stripped when it is tightened. The same method of heavy Teflon taping, hand-tightening, and quarter turn with pipe wrench, solved that problem too. I would caution other pool owners to be careful about over-tightening the fitting on their discharge pump. Not all of them are built the same. If you go past the threads it could definitely cause damage to the pump fitting. Hope this helps some others.

Any decent plumber should have left the system water tight and unless you have "O" rings or washers Teflon tape should be used with screwed joints
What you did was what the so called plumber should have done
