Leaking Pool Pump, what to replace?

[kucster]

Hello I noticed over the weekend my pool pump has started leaking I think where the motor joins.
I have an Hayward super pump 2, 1HP.
From my research I think there are seals that can be replaced although most of the info I found said it should be leaking from the bottom and mine is leaking from the top, see video at link below.
I'm wondering if it would be worth it to replace the seals, the motor, or the whole thing?

From that video, it looks like a very old pump. If it were me, I would probably replace it with something new.

Thank you for your help!

Is there anyway you might be able to recommend a new pump?
My pool is 13,000 gallons and I use a cartridge filter that is 75sq.
My currently pump is 1HP do you think that is sufficient?
I did the calculation and I don't think a variable speed motor is going to save me enough to make it worth it but I see Hayward has an energy efficient single speed, do you think that would be worth it?
Thanks!

Hello, no problem. Looks like an easy fix would be a new shaft seal. Can you provide a better picture of the pump overview, not so close. You may want to consider getting a 2-speed motor. Once the shaft seal starts leaking, water gets to the bearings, bearing start rusting/seizing, which produces more heat in the windings, then then the insulation breaks down on the windings causing the motor to short out. Then you'll need a new motor.

Thank you for the quick reply, I will send the pic tonight.

I'm sorry for the delay, here are the pictures, thanks again for your help

Nothing appears wrong with the wet end of the pump. I'd replace the motor and be done with it. If you're looking for some energy savings replace the single speed with a two-speed motor and run it in low most of the time. Do you have any water features?
Here's a link to the owners manual if you don't have it: https://www.hayward-pool.com/pdf/manuals/SuperII.pdf

Replacing the motor is pretty easy, google it, you'll find lots of videos, also don't forget the shaft seal. If you're really looking to save some money, you can get a refurbished motor, usually 1/2 the price of a new one. Check craigslist. Here in Florida there's no lack of motors.

By replacing the motor you won't have to redo any plumbing or such. The motor is a replaceable part.

If the housing is good, I would suggest going to a 3/4 hp motor, spx3005c impeller and ps-1902 seal.

You have a single 1.5" line for suction and return. You really don't want to put a lot of horsepower on that. More hp will mostly be wasted trying to move water through the plumbing.

Thank you for the response I'm all for going smaller as I image it would be cheaper to operate.
Would a 3/4 HP motor be ok with a pool cleaner, I am currently using the below.

I was using that cleaner. It was would work on high speed for me no issues. My flow rate was about 48 GPM. On low it would work with a very clean filter. Needs a flow rate of at least 25 GPM. You should be fine.

 

[JamesW]

Should be good for the cleaner.

Thank you so much for your continued help, would I also need to replace the impeller to work with the 3/4 HP motor or will the one I currently have that is working with the 1 HP work?

I also found the below Energy Efficient Motor, do you think it would be worth the upgrade?

It's a bit more cost but should save on power. Payback depends on usage. Either way should work.

You would have to replace the impeller.

Thank you so much for your help, I took a screenshot of my cart does that look about right.

There are 2 motors in the cart because I can't decide on what to get, my calculations show I could save about $80 a year with the efficient one but I'm a little worried about it lasting as long as the other one because of the extra electronics.
Any thoughts?

 

[JamesW]

I would say it's 50/50 on the motor. They don't last very long, so it might not be worthwhile paying extra.

For the seal, I would go PS-3868 or PS-1902. The seal is the critical component. A regular seal is much more likely to fail, especially if the pump ever runs dry.

Note: I think that your leak is due to a leaking housing gasket. I don't think that it's due to a cracked housing. However, it's hard to tell so make sure that the housing is ok before ordering the motor.

 

[kucster]

Thank you for your continued help.
Would I be able to see the housing crack from the outside or would I have to take off the motor?

 

[JamesW]

You can try tightening the bolts (don't over-tighten) or replacing the housing gasket to see if the leak stops.

Not sure it's worth changing out the impeller and motor, you're energy cost are pretty cheap, the saving is going from a single speed to a two speed. With a 2-speed on low you move 1/2 the water but at a 1/4 of the cost. I'd get a 2-speed 1hp, and keep your current impeller. The saving between a 3/4 and 1 hp isn't that great.

 

[kucster]

I was wondering if the 3/4 HP motor would save enough to make the impeller worth it.
I think to start I might just order the, Hayward SPX3000T Housing Gasket and the PS-3868 Seal Assembly. If the leak goes away then I'll order a new motor does that sound prudent?
