Why don't you see if you can get more details from the retailer as to what they are proposing. Get model#s for the pump and filter. What they are suggesting may or may not work but we need the details to make that determination.

It was a sta- rite 22" sand filter with a 2 hp pump. I am 99% certain it was an above ground model because we were talking about the pump being built in to the sand filter. I am buying my pool from them but not necessarily the equipment. Anyway, not sure if that helps or not, but I will post more when they get back to me.

Here is the pool
http://radiantpools.com/pools/detail/metric_round/
 
If it is a sta-rite combo unit, then it probably is one of these:

http://www.pentairpool.com/pool-pro/pro ... em-400.htm

However, I don't think it comes in a 2 HP version according to the web site. The the SRCF2022DO2160 combo unit comes with a 1.5 HP Dynamo which is actually has the same performance as the 1 HP Dynamo and neither is a terribly big pump but I think it would work fine with your setup and it should support solar as long as the solar is not installed too high and they don't use too many fittings getting from the pool to the pad. The downside to that combo unit and in fact all combo units is the filter size. It is a little small for your pool size but that just means cleaning it more often. So if that doesn't bother you much, you could stick with what they are proposing.

However, there are a couple of trade offs that you need to consider and there are two ways to design this system.

Option #1

If you go with the combo unit, you will want to keep flow rates low to keep the filter working properly so having long runs of 1.5" plumbing is not a bad thing in this case. Plus combo units are cheaper than buying them separately but the downside is the system will cost more to operate ($$/turnover) plus you will be cleaning the filter more frequently.


Option #2

If you go with a separate pump and filter, you can up size the filter so it can handle more flow rate and if the filter can handle more flow rate, you can up size the pipe (2") to reduce head loss so the pump can actually deliver higher flow rate. In this case, the same 1.5 HP Dynamo will operate close to 20% more efficient than in option #1. Plus you will be cleaning the filter less but again, the downside to this is that the pump and filter will probably cost more than in option #1.

I wanted to give you both options because both will work in my mind, they just have different trade offs. But to give an idea of the difference, I modeled two systems based upon your specs and here is what I come up with:

Option #1 - Combo Unit, 2.3 sq-ft filter, 1.5 HP Dynamo, all 1.5" plumbing, single 1" return eyeball
Option #2 - 4.6 sq-ft filter, 1.5 HP Dynamo, all 2" plumbing, dual 2" return eyeballs (that size pool should have at least two returns)

mas985, thank you.

They have to have more than one return in that thing or I will have to get out the hole saw :D.

I am more interested in getting the right stuff than skimming by. The up front costs don't bother me as much as the ongoing ones.

So you are saying to get the dynamo and maybe this sand filter if I understand you correctly?

http://www.poolsupplyworld.com/poolsupplies/poolfilters/products/140210.htm

I don't know how to convert your numbers for a cartridge filter they all say 75, 100, 150 sq feet etc. Maybe one of the Pentair Clean and Clear models?

Not sure if you caught it but I am actually going with the natural gas heater. Solar is an after thought depending on how the gas bills work out this year, but it would be nice to have the option.

Finally, would it be better for me to move the EQ pad closer to the pool? i can put it anywhere along the part marked 33' in my sketch up. I would have to run a longer natural gas line/ electrical line, but that could happen.

Thanks for all the advice.

You will find many varied opinions on filters. So to be contrary our fellow Minnesotan, mcoonan :mrgreen:...I give you mine.

During opening my sand filter has been backwashed once so far and will get one more. Takes 3 minutes each time (including the rinse step), does require some time (not my time and only about 100 gallons of water) with the hose over the side filling it back up. I then expect, if it is like last year to a month and feel guilty like I need to backwash, but I don't, and I usually go two months before my next backwash (but let's say a month). Then in the fall, because of stuff falling I might have to backwash 2 times close to closing. Also, since I have the sand filter, if I have some mess I have to vacuum I can catch it in the filter, and then it's just another short 3 min backwash cycle. You can do that easily with a cart.

Total time normal maintenance spent "cleaning" filter for a normal season= 18 minutes...for the whole season!

In addition, if you do have to clean up a algae outbreak, it's 3 minutes per backflush cycle and it can be difficult (constant cleaning) if you have a cart (or DE) filter for that matter. Of course that could be alleviated by not letting growth occur in the first place.

Winterizing is: crack valve to winterized position, unscrew drain plug...done.

Water clarity is excellent (day and night) as all of us BBBers always get great compliments from other pool owners who see our pool water :party:

Here I thought you had to backwash and all that jazz on a weekly basis. I guess I was wrong on that part.
But I will still stick with my opinion (we all have our own - thank God) that a cart filter is easier to care for.
It does not matter what filter system you choose, once it is all in (that is part of the price we pay) just remember to:
HAVE FUN and Enjoy your Pool!

One thing I neglected is that the 4.9 sq-ft filter will probably need at least 75 GPM for a backwash and the Dynamo may not be able to provide that in backwash mode. It might still work ok but the 1 HP Superflo should be able to provide that backwash rate and it is a little better suited for solar and a little bit more efficient than the Dynamo. I like the pump lid better too. Overall I think it is a slightly better pump.

If you wanted to go with a cartridge, I would recommend a 400 sq-ft or larger filter such as the Clean and Clear Plus CCP420.

As for moving the pad, as long as the installer uses 2" or larger pipe, you should be ok with a remote pad.
 
I talked to the guy at Radiant. He said I can either tell the retailer to add another return or just do it myself. He also said in MN I can use rigid PVC above ground but need flex PVC in ground because of movement.

I am assuming the returns should be close to opposite each other and it would be wise to run them outside the exposed side of the pool (around the edge a few inches underground) which means I will have about 30 feet of flex pipe to the first return and 80 to the second.

Does that change anything with your calculations?

So far I am planning on this pump and this filter

http://www.poolsupplyworld.com/poolsupplies/poolpumps/products/340042.htm


http://www.poolsupplyworld.com/poolsupplies/poolfilters/products/140210.htm

Those are both for in ground pools so I just want to make sure they are the right thing. If there is a cheaper filter that would work I would appreciate a recommendation.

As I mentioned before, that is the penalty for going with a separate pump and filter. The combo units are much cheaper:

I ran rigid for my pool, but I think I agree with the flex being a better choice for underground here. I didn't want to pay for it and my pipes are not very deep (and my run is short) so that I can replace them if needed.

Those look good, though I would be interested in Mark's thoughts on the 1 hp superflo being enough to backwash that filter. From Mark's table the 1 hp superflo with plumbing curve C still only goes to 70 gpm. Would a 1.5 hp superflo be a better fit? pn 340043. Looking at pentair's curve the flow rate with plumbing curve C might be above 80 gpm? That would be closer to pentairs recommended 20 gpm/sq. ft. backflushing recommendation.

Thanks Linen. I will wait to hear back from Mark on your suggestion.

Secondly, just a note for posterity :D. While speaking with Radiant I mentioned the idea of insulating the bottom with 2" insulation and covering it will a gorilla pad mat to keep the edges of the pavers from puncturing the liner. He suggested taping the between the pavers and the insulation, but otherwise thought it was a great idea. They are pretty big on their insulated sidewalls saying that no one thinks about the heat lost through the sides and bottom of the pool and thought this was a good idea to shore up heat loss from the bottom. With the sunlight beating we get in the pool area of the yard and the heater I might just have an Arizona pool in MN.... :D.


Also just ordered the pool- now just waiting to see what pump/ filter to buy and I am off to other challenges- like installation, ownership and seeing if my gas hookup can handle a 400,000 BTU's. The lady at Centerpoint shuddered a little I think when I threw out that number.

Those look good, though I would be interested in Mark's thoughts on the 1 hp superflo being enough to backwash that filter. From Mark's table the 1 hp superflo with plumbing curve C still only goes to 70 gpm. Would a 1.5 hp superflo be a better fit?

I was targeting 15 GPM/sqft max for filter mode. Backwash mode will have a little more flow rate because of the reduced head loss when bypassing the return plumbing so it should be a little higher and backwash fine. Plus looking at this from a theoretical point of view, a filter should only need slightly more flow rate to remove the dirt that there was placed there in filter mode. Slower flow rates in filter mode means that the dirt will not get embedded into the filter as deeply and should be easier to remove. Part of the reason that some recommend 20 GPM/sqft for backwash is probably because that is also the filter mode rate. 15 GPM/sqft is only recently been put forth as a recommended flow rate so probably not too many existing pools are designed that way.

But if you do decide to up size the pump further, which I don't recommend, then I would go with the Whisperflo WFDS-3 or 24. Flow rates about the same as the Superflo 1 1/2 HP but the energy use is 10% less.
 
Great points Mark! Seems like everything points to that 1 hp version then, which is nice since during filtering it should be more efficient than the 1.5 hp. Note, the 1 hp superflo is 230 volts (not 120) but since you are doing a new install that shouldn't be a problem.
 
Sweet- now I can fill out my sig line will all my cool new gadgets.

Thanks for all the help guys, I think I have it all covered now.....


....just kidding- I'll be around to take advantage of your services as all my stuff starts to roll in.
 
Just wow is all I can say : ) soooo, I have the same
Size pool and the filter that came with the pool seems
To be extremely inadequate. I don't want to sink 1000K into
A filter/pump combo, so what am I looking at with a S210T filter
And a 1 HP dynamo. I am not sure what dynamo. I can't tell.
The volts are 115, 12 amp, 3450 RPM. I thought I could better
Tell the exact pump, but can't.
 
Sorry this posts seem so short. I am typing on a phone, and am so
To start the install this weekend,
Unfortunately, I had totally forgot about the filter size
Might be too small, considering it is bigger than the one that
Came with the pool.
 
Here is a picture to a filter and pump for $200. The guy says it came off an inground pool. I asked him about how he moved and he seemed as if it was taken care of. Is there anyway that I can look at it when I get there to make sure nothing is broke? I also can not tell the manufacturer. I doesnt look like the standard hayward sticker.
