New Hayward Pump, inlet/outlet wrong per mfg spec?

[GenericHbomb]

I think I am honestly just confused but I dont see how.

Posted a while back about replacing pump which ended up not happening due to me finding and repairing bad wiring.


This year I decided wanted to go with a new pump. Picked up the hayward super pump 1hp, current pump is a 1hp.

Model: w3sp2607x10

When I started mapping my pvc I realized the inlet/outlet are 2". Not the 1.5 spec'd. Im under the impression hayward doesnt move to 2" pipe until you hit 2hp.

All my piping is 1.5.

Im confused on what happened here, Hayward change all models out to 2" or?


Im lost lol


The real question I suppose no matter what is an I upsize into a 2" connector in and out of pump? Not looking for flow rate, just dont want to cause issues.

I can't see the threads in the picture with the tape measure. Are they at the end of the tape, or on the inside ring at the 0.5" mark?

G,

Not sure I understand the problem. Just reduce down from the 2" port on the pump to 1.5" to match the plumbing on your pool.

It should not cause any issues.

It looks like all their super pumps have 2" ports..

That's a 1.5" fitting. Edit - It might be 2".

The pipe size is the inside diameter of the pipe and not the size of the outside diameter of the fittings.

2 x G = 2-1/16"

According to the manual the pump includes a bushing kit to reduce to 1-1/2" pipe.

Actually, Hayward shows that the new pumps are 2".

The dimensions are difficult to tell.

On closer inspection, it looks like it is probably a 2" fitting.

New efficiency standards probably made Hayward eliminate the 1.5" ports, which is a good idea.

For a 1.5" fitting male thread, the O.D will be about 1.9" to about 2".

For a 2.0" fitting male thread, the O.D will be about 2-1/4" to about 2-3/8".

Get a 1.5" or 2" male adapter and see which fits.

In any case, you can just use a reducer bushing.

You guys were all right. All set and installed. Except appears pump is dead after one day, so gotta figure that out.

Was in the pool shed backwashing. Turned pump off, switched to rinse, turned it back on and pop and a cloud of smoke came out of the back..

I pulled back cover off and checked for anything. Checked the impeller. Turned it back on and its running. Little concerned, figured a capacitor blew but I am not seeing it.

Have a message out to Dohenys. Not sure if I should let it run. Appears to be running fine.

In good news, new straight pipe into pump is working well. Great flow and no bubbles. Cant catch a break though

Um, that’s what we call a “Bad thing”.

Maybe a wire shorting to the case?

Can you show a picture of everything?
