I have a newly installed Hayward 1.65 THP VS Pump. It was was installed by a pool guy who left three inches between the pentair selector valve and the motor seal flange. In the owners manual on page 5 it says for 1.5in pipe 7.5 inches of straight pipe is required. The new motor started making a ticking noise the a squeeking noise. I reinstalled the old super pump ordered and recieved Part APCAS201 mhotor seal from youguys. When I reinstall the new pump after changing the seal could I put 2in pipe over the pentair valve(it fits) to the motor flange(it fits) and increase the lenght to 10inchs as per manual. Would this be a good idea. At lower rmps the new motor does show air bubbels but I'm told this is normal for lower rpms.
Thanks
