Hi I am looking to replace my inground pool pump with a Pentair Superflow Single Spd Motor - Pretty Sure i need a 1 Hp Model (vs. 3/4 hp) but wanted to get your thoughts - 24000 Gal Pool; 1.5" PVC Piping; Need about 51 GPM to tunrover in 8 hrs From what I read maximum from 1.5" pvc is about 53 GPM Estimated Total Dynamic Head - 50 Feet I want to make sure I have enough hp but not too much to risk cavitation can you let me know your thoughts?

Hello Ron - Based on all of your variables, we would recommend the 1HP Pentair SuperFlo.

I have a Pentair pump part # 340038 with a date of 2008, should a new Pentair hook up to existing plumbing? My existing pump just last night got really noisy, almost a whining sound. Is this an indication pump is going out?

A  Answered on 4/25/2015 by InyoPools Product Specialist Alex V.

Dan, The pump should line up the same way as your existing Pentair SuperFlo. It sounds like the motor is failing/has failed. You can also consider replacing the motor and seals.

I have a Pentair 340038. Motor sounds bad. What would you recommend to replace motor and other seals needed? 110v. 2 speed with timer would be great.

A  Answered on 4/29/2015 by InyoPools Product Specialist Robert M.

Hello Fred - The correct 2-speed replacement is model B2981T. This is a 3/4HP full rated motor but the total HP is the same as your current motor (1.25). The shaft seal, housing o-ring, and diffuser o-ring should be replaced as well.

pentair part- 340038 , leaking between motor and pump, what would i need to correct this ? thanks

A  Answered on 6/4/2015 by InyoPools Product Specialist Patrick P.

Hi Natalie, I would suggest a Super Flo Shaft Seal, Super Flo Body O-Ring and a Super Flo Diffuser Seal. The changing of these 3 items should stop your leak.
