Hairline crack developed in bottom of old gunite pool and apparently caused a slight leak. Crack has been filled with pool putty and leak apparently ended for now but what might i expect in the future? I will continue to monitor the situation. What else, if anything, would you suggest doing...

sorry for lengthy post but i am baffled by bubbles. my pool suddenly has more air bubbles coming out of one of the returns. I've historically had bubbles from that return for a little while after stopping and restarting the pump, but now it is continuous. Pool has three returns, but the...

in attached pic, i've added a finger pointing at what i think is the air bleed. Correct? I've never used it until today, and i'm just not clear on the concept. i expected some air to come out of the little hole, because i definitely have a suction side air leak, but it immediately looked...

when running pump at low speed there are air bubbles coming out of returns, but no bubbles at high speed. Why is this? Looking through the transparent lid of the pump body, it looks almost full of water at high speed, but only half full at low speed. I guess it takes the pump less effort to...

forty-year old 23000 gallon gunite pool with two skimmers and one floor drain, hayward superpump with new v-green variable speed motor. I've lowered the water below the skimmers to allow for tile repair but it might be a few days before i receive the thinset and grout. Will it stress any part...

my v-green 165 motor was fine for 4 years but suddenly has become very noisy. There was a high pitch squeal at first, which made me think bad bearing. The squeal went away after a few days but the motor is still way too noisy. I've pulled it out of the pump body and inspected the impeller...

I called Poolife support line and the guy explained to me they have two different NST products: one formulated for use in skimmers and one for in-line feeders. He said do NOT use the feeder product in a skimmer. The label on the feeder formulation (bucket with purple lid) is not crystal clear...

I'd like for my white plaster pool to be a little warmer, and i've been told that a dark finish replaster would make a significant difference. But i'm concerned that dark finish would make it harder to see if algae starts to form despite my best yet sometime imperfect efforts to maintain FC...

i suddenly realized there are considerable patches of algae growing in the rough-textured underhanging edge of the concrete deck just above the top tile joint. What do you think about my spraying it with bleach before i brush it and let it fall into the pool? into the

Many sources say that baking soda acts as a "buffer" to prevent pH swings, but i just don't get it. It seems to me that baking soda is more just a "neutralizer" to acid. To try to raise TA i add baking soda, and the pH goes too high, so i add muriatic acid to bring the pH back down, but it...

i bought a new, still in-the-box v-green 165 pump last month and installed it, but there was nothing in the box about warranty info so i called Regal Beloit (the mfr) just to ask if i should register it. They said no need to register. They said the warranty period is 2 years from install or 3...

this article Pool School - Suction Side Air Leaks is helpful but it almost sounds like zero tolerance for air in pump basket. My superpump basket seems to stabilize with about an inch of air in the top, resulting in some swirling and some occasional small bubbling at return -- is this...

wiring instructions for v-green 165 motor are for black wire to go to L1 and for red (or white) to go to L2. But the attached pic from step 46 at http://www.inyopools.com/HowToPage/how-to-install-a-variable-speed-v-green- 165-pool-motor.aspx shows black on L2 and red on L1. Is the pic...

Anybody have experience / opinions on relative noise levels of Century V-Green motors vs Pentair intelliflo? Lots of folks on this forum like Pentair and i was leaning that way, but i have a Hayward superpump and i could more easily and much less expensively just pull out the current one speed...

i saw a video that says if you have 1.5 inch plumbing, you can use an adapter to connect to a 12 inch straight run of 2 inch into your pump. Anyone agree if this is ok with an Intelliflo? thanks

Can anyone comment on running intelliflo pump in cold weather? I am thinking of buying one (to replace old single speed pump) and i see it has an anti freeze feature that can automatically turn it off "to protect the pump." Would it hurt the pump to just keep it running continuously during...

When do you need to run a VS pump at other than low setting? I'd think if low setting moves enough GPM to turn your pool water over in a day, you wouldn't need high setting except maybe when vacuuming or running a water feature. But a local pool eqpt sales person told me a hayward VS should...
