Need to replace pump

[sasgharian]

We have a 50K IG pool with a Hayward DE-6000 filter. We think the pump is orginal equipment(we've only been in the house 2 yrs). We want to replace the pump with a more efficient model. What would you suggest? I don't know if it matters, but we use a commercial Dolphin for the pool cleaner. Thanks!

Need some background

What size is current pump?

What diameter/length are the suction and return lines?

Do you have a spa or water feature? How many jets? Run off same pump?

Do you also have a heater and/or solar?

All these things are important when deciding pump size. Also, here are a couple of good sites to help you decide what pump you need:

hi, I am also in a similar situation in need to replace my pump. Here is my setup:

1) Hayward dual speed 2 HP pump using 230v and 9.1/3.4 AMPS (Model SP-1615-Z)

2) ~26000 gallon concrete pool

3) 1.5" incoming and return pvc pipes

4) Pool is approximately 15ft from pool.

5) Nautilus FNS 60 filter

I also use a Polaris automatic cleaner. What brand and HP would recommend to save electricity. I probably would only use the pool a few times a year. A pool repair guy suggested that I get a new Pentair 3/4HP Whisperflo pump and would do it for $625 total with labor. Anyway I can do it for cheaper? Also I am a total newbie when it comes to pools but I am willing to learn as long as the mistakes are not costly.

Thanks!

Hi, Are you sure the suction (incoming) line is only 1.5"? With a 2 hp pump the suction should have been 2.5 although many builders will install 2".

Madgame, I assume that you must have several suction and return lines at 1.5" in parallel. If not, as Zina pointed out, 2 HP would be way overkill.

If the pump does not also run a spa, water feature or cleaner, you can probably go with the 3/4 HP pump. Otherwise stick with the 2 speed.

Also, you can do it for cheaper only if your willing to install the pump yourself. Otherwise, seems like a pretty reasonable price.

Sorry for the misinformation as I'm a newbie and learning as fast as i can. The pipes coming from the ground attaching horizontally into the pump is 1.5". The size of the piping between the pump and filter is 2". The return pipe going back to the pool is 2" but soon decreases to 1.5". Again I may be wrong about this as there are other things attached to the pipes including a heater that is not being used and a booster pump for the polaris.

On average, how long would it take to replace a pool pump? Thanks again!
