pump hums

Just opening the pool and i primed the pump, but it just hums. same thing happened last year when i first opened the pool, the pump just hummed and i followed the advise of this forum in explaining to me how to get the impreller to start, which it did and the pump worked all last summer without any problems. now it's doing just as last year, the pump just hums.... my pump is 15 years old, it is a hayward superpump, self priming. i have an inground 21,000 gallons. my question is, should i do as you guys instructed last year with the impreller and try to get the pump running or do i just need to go ahead and buy a new pump since this one is 15 years old and it done this last year? please advise me as to what to do. i really need your help. thank you

I would try what you did last year first, you have nothing to lose, if it doesn't work, then buy a new pump:D

15 years from a pump. Pretty good. That pump owes you nothing. replace it.

Yeah...it ows you nothing but if it is a simple fix then save some $$$. Check this thread:

Could be something as simple and cheap as a crummy starter switch or bad starting capacitor.

it was a simple fix of just spinning the impeller and i have had no problems since. but i am concerned of the pumps age and wanted your opinion as to whether you think i should think of replacing it after this year. looks like my liner is also on its way out as it is also 15 years old also and i am now getting tears above water level.

If it would give you peace of mind then replace it. At least do your homework and figure what you want and where to get it when the time comes. I'd milk the old one for all you can. Then again, some people say I'm a packrat and never replace anything unless I have to.

YA THINK???? You forgot to tell the part about not only will you never replace anything unless it is totally dead, but then you want to keep all the old useless dead stuff around the house, too!!!! :eek:

i have a heater and i noticed a leak from the screw that is underneath the pipe that goes to the heater. this screw is what i have to unscrew when i close for the winter. i did tighten it when i opened it but there is a drip. i put a small pail underneath it last night and this evening the pail is full. when i emptied the pail i also noticed the water was warm to touch. i do not have the heater going yet so i couldn't figure why the water was so warm. then i noticed the pump motor was hot to touch...i have never noticed the motor being hot before, but i never really have ever touched it...is that normal? i shut the pump off and i could hear a hissing. i put my finger underneath this screw and the hissing stopped. can you give me advise about the leak and if that is normal about the pump motor. thanks

That drain plug is easy. Take it out and wrap about 10 turns of teflon pipe tape on the threads and screw it back in. Tighten until the leaking stops and be careful not to overtighten. As for the motor, they do run hot especially if in direct sun. Think I remember 140F or so on mine with an IR thermometer and that's inside a poolhouse. Could the water just feel warm because the air was cool? Only way a pump could heat water significantly is for the flow to be almost blocked and pumping only a trickle then all thre energy from the motor goes into heating water rather than moving it.

I just had a similar experience with an old Anthony that became sick beyond repair. The advantage of having a Hayward is that everyone carries new ones and can serve old ones.
You can get a new Hayward SP 1 HP at a store for $350 and for $300 plus shipping on the Net.
I got mine at Seasonal brick and mortar pool supplies store for $350 with two years P&L warranty.

If I were you, I'd take the old pump to a dealer who offers both repairs and new ones at a reasonable price. They can open it up and assess what needs to be done at what price. If only one or two parts need to be replaced and everything else is in good shape and there's no corrosion I'd go for repair if it's no more than $100. Otherwise I'd go for a new one.
Make sure you tell the dealer that you're committed to get his service/sale no matter what way you choose.
Be cautious : Some dealers may quote you $500 for the same pump. Make sure you have a quote of $350 or less before you bring it for repair.

not had anymore problems with the pump. but i just tried to fix the leak at that screw but it didn't help, actually i made the leak worse so i may not know what i am doing. i took the screw out and wrapped the tape around it. when i turned the pump on it leaked worse so i took it back off. the screw is like a wing screw(i guess that's what you call it) and it leaks from the middle of the screw. can you tell me what i have done wrong or what i can do to fix it? thanks.

I've got the hum on one of my pumps too. I tried spinning the impeller and it won't spin at all. Is this a sign that the pump motor is dead?

Try what Al has said in the past by hitting the pump motor with a 2x4. Not hard, but hard enough to give the contacts a bump that can get them to start. If that doesn't do it, you may need a new capacitor for the motor. The pool stores get about $25 for these, but you get get them at Grainger for about $5.

Good luck.

If you have tried this make sure you struck the pump long ways closer to the back part of the motor with the 2x4 not just in the center of the pump.

my question was what to do about the leak at the screw?????????0.

"...the screw is like a wing-screw and it leaks from the middle..." (Sorry, I've never mastered quoting from other posts:o ) It sounds as though you might be describing a petcock. They can wear out. If it is then you can match it and put a new one in. Good auto parts stores are a source. Around here, NAPA would be my first stop. Hope this helps!

I agree with Sumo....and if you can't find a replacement petcock then just get the right size pipe plug and use teflon tape on the threads.
