New pool build -- pipes and pump sizes

[jasontx]

I think the Intelliflow sounds great and I think it is likely very energy efficient, but I don't quite trust their calculator. It seems to give some odd results to me -- but what do I know.

I'm not sure why Hobert went from Hayward to Jandy. I think a lot of customers like the PDA so I wonder if that was part of it. Hayward announced their version of a wireless / waterproof controller about a month ago (and Hayward was off my list until then). My salesman said the change to Pentair was driven by the potential energy savings of the Intelliflo. Although I don't think that is going to be the base pump they are going to offer, maybe they saw having that option as a potential differentiating factor. I'm sure the equipment manufacturers also try and get each other's clients so it might all be incentives / financial too.

I read your post in the other thread Beary -- sounds like we are experiencing the same storm system. I have drawings but keeping them handy to pull out and show people makes a lot of sense. As Hobert uses mostly their own people and doesn't subcontract very much of the work, you would hope that would help, but I'm not relying on it.

Yes, the problem for me was my pool builder was never around while I was trying to show where the workers were doing it wrong. I told him one day that I was tired of arguing for an hour to get small changes made. It was mostly the difference in languages that cause the problem. If I could just point to the drawing, then the workmen could see what I was talking about.

The other reason for a drawing is sometimes even the pool builder didn't understand why I wanted something, so he said he would do it, but ignore me thinking I wouldn't know the difference. We wanted fountains in our two tanning decks and I wanted the plumbing run where I could turn them up or down, or even off. Well the workers put all the fountains and returns all on the same pipe. I argued for an hour with the forman that I needed the fountains on a seperate pipe so I could control them seperately. There was an urgency because the crew was about to shoot the gunite. And once that is done, we would be stuck.

He put a seperate pipe on one fountain, but not the other. Not until my pool builder was showing my equipement was I able to turn valves on and off to show him the effect I wanted. His eyes said it all when I showed him why I wanted to turn off the one fountain and I couldn't. If I had a drawing made up at the time, there would have not been any arguing. Just do it.

I am very happy with my pool and I think our builder is one of best in the city. But I would have done it different next time. For one thing, I would build it in the winter where the crews aren't so pressed to jump on three jobs a day.

Another thing, check out who does the concrete decks.

Keep us up on the building, I know I whined a lot here, but it is actually very exciting.

I understand what you mean about the Pentair calculator, however You can do the math yourself as well. I am getting 580 watts to get 40 GPM flow now, I was getting 50 GPM but down sized my return eyes to keep the pressure up for my chlorinator. So I get a complete turn in about 16 hours. This should cost me under a buck a day. My neighbor runs his pumps for 9 hours @ 70 GPM @ 5.4 amps to turn almost the same water. 38K gallons vs. my 39.4k gallons. Note these #’s are from memory which is questionable at times. I have done the math before and I saw savings of approx 50% per day of what my neighbor is using. So the savings is there, but who knows where power cost will be next year. Right now the power rates are coming down again, but just a little.

The 4x160 is also a little cheaper. If I was not going to go with a full Intellitouch system I would have gone the 4x160 route. Honestly you just use about 3-4 settings anyway. You can program the 4x160 to do what you want without the monitoring functions. According to the Pentair rep the equation was simple. Slower flow = more efficient power consumption. So I use more hours but at a much lower flow rate and lower power consumption.

If not an Intelliflo I would definitely look into two speed pumps or energy efficient pumps. Remember this sucker runs 7 days a week 6-10 hours a day and even more in the summer.
