Dual Speed or a Variable Speed for a plain Jane pool.

[mas985]

Here are my estimates,

Current Setup:

1.8 Turnovers/day
200 kwh/month
$21/month


Two Speed Pump (WFDS-24):

1.8 Turnovers/day - 30 minutes on high & 6.5 hours on low
99 kwh/month
$10.24/month


Intelliflo:

1.8 Turnovers/day - 30 minutes @ 2700 RPM & 9 hours @ 1000 RPM
61 kwh/month
$6.36/month


So either pump would save you energy costs and the Intelliflo a little more. You could also save even more if you reduced the runtime to one turnover per day.

Given there is a rebate for the Intelliflo and you can find one with a timer for less than $900, it probably makes more sense to go with the Intelliflo.

Wow Mark, thanks. I sent some pictures over to the email provided above. Hopefully the plumbing will work with the Intelliflo.

Is there a website that you folks recommend over others for quality, customer service and price?

again thanks.

Thanks Ben. I plan on redoing the plumbing and electrical this spring. Is there anything that anybody sees that I should change or add? I am not to sure what that 1" or 1 1/4" is that is capped of. I assume it is for a threaded outlet on the inside of the pool on the side that does nothing right now, but not sure what is supposed to do.

Mark's already started; I'm going to let him work with you on the details if that's OK.

The capped line was probably a pressure side cleaner line at one time. They may have capped it off because it was leaking so if you want to make that active again, I would pressure test the line first to make sure there isn't a leak.

It looks like whomever plumbed the heater took some short cuts. You could fix this pretty easily by dropping the 3-way valve to the same the level as the heater exit so you could eliminate a 90 and the coupler but you would probably need a new 3-way valve to upsize the branch line. This could be a future project at some point since it is completely independent of the pump and I would only redo it if you plan on plumbing in the cleaner line.

As for the pump, the replumb should be fairly simple and you have enough line after the suction side 3-way so you shouldn't need to touch that. Just make sure you use at least 2" line on the pressure side, replace all the pipe from the pump to the filter, and it looks like the suction side may be 2.5" so carry that through the suction side if possible.

Also, do you have a spa? That would change the two speed choice if you decide to go that route. Otherwise the Intelliflo would handle that fairly well.

As for the pump

Hey Mark, I have a few questions again. When you say they took short cuts and I should lower and remove the 90*, is that because (on the pressure side) the more 90*s you have you lose pressure? Or are the short cuts more extensive.

I went out and measured the pipe again. The suction side is 2". The pressure side to the spa (I believe it goes to the spa) is 2". The pressure side to the pool is 1.5". Maybe be vice/versa. Those are going in to the ground. Will the 1.5" be an issue when plumbing for the Intelliflo? Also, it has 1.5" going to the filter. I have never looked under there, will I be able to take 2" to the bottom of that type of DE filter?

When I re-plumb this I want to do this in one shot. So, I was looking around for some plumbing schematics, and I believe this one will work. I am correct in my thinking? If it is, what is the purpose of having 2 valves for the spa, especially the "Spa Make-up" valve before the check valve? What is the purpose of having the 2 directional valves for the Spa?

Thanks again for the help.
