    Not sure what I have with the house I bought.

    So, this is my first house, and it comes with a pool!!! My parents had an above ground 15' diameter and my grandmother had an inground pool and I helped with both. But I'm realizing there were several things I didn't pay close enough attention to.

    The previous owners closed the pool for me. We saw the house w/ the solar cover on the pool, but I could tell the water was nice and clear. They had been using chlorine, so I'll probably go with that for now.

    First question: The pool is 15' by 30'. I'm guessing about 4' deep (it's an above ground but set in the ground.) How can I figure the gallons?

    Second question: This was a big dumb move on my part... I was cleaning things they had left out of the basement. I thought they had an old pump down there, but now I realize it was the only pump. Believing it was an old pump and not thinking, I threw it out. It's long gone... (It was one of those late nights you have moving into a place when you really should stop before you do something like this.)

    The sand filter is outside, wrapped in plastic, and I can see where the pump would have set.

    What do I need to look at to determine what kind of pump I need to get.

    The cover of the pool has collected some rain, and there is a small pump I found in the basement that I've used to remove the water from the top of the cover. (I do not run it all the time, just for about a half hour at a time.) Is this the right thing to do?

    I suppose I'll have all the chemical questions to ask in the spring when we want to open back up. I figure I'll start asking now to give myself time to prep. Thanks in advance.

    Re: Not sure what I have with the house I bought.

    Given the opportunity I would go with a 2 speed pump. I would guess you need around 1.5 hp for the pump. Whisperflo seems to be a popular choice for pump model. Can't be sure about the depth of the pool since it may have an expandable liner in it. Go over the documents from the sale of the house to see if the pool info was included anywhere. You also may try calling the realtor that listed the house for the seller. They may be able to contact them and get that information for you.

    Welcome to TFP.

    Bummer about the pump. We've all pulled bone-headed stunts. You won't do that again!

    First and best thing you can do for yourself is to read Pool School. Then, learn how to use the Pool Calculator. It has a section toward the bottom that figures the gallons for you when you enter the size of the pool.

    If the previous owners used liquid chlorine that's the best thing you can do.

    Read up and then come back and ask questions.

    Re: Not sure what I have with the house I bought.

    Hmm... using the Pool Calculator, I figure I'm about 13,500 - 16,800 Gallons. (depending on if I'm 4' or 5' ft. deep)

    According to the Pump Basics page: pool-school/pool_pump_basics I should only need a half or 3/4 HP motor.

    What would be the difference between this:

    this:

    As your reading of the pool pump basics page has doubtless told you, having a bigger pump is not always the better solution. The WhisperFlo is explicitly recommended for inground pools, though I believe the other two you mention would be appropriate (but perhaps oversized) for your above ground pool. How large are the existing return and suction pipes for the pool? If you have 1.5" suction and return pipes, a 1 HP pump might be overdoing it -- you want the right size (hp) pump that will turn over the pool's volume in 4-8 hours.

    From what I read on the forum, AG are usually 4' unless you've got something unusual going on. So I'd go with the lower number unless/until you have some reason to think it's bigger.

    Re: Not sure what I have with the house I bought.

    As Paul said, most AG pools are 48, 52 or 54" deep. Even then, the water level will be less than that. If you have a sunken end or middle section then you'll have more volume and you'll most likely have to guess at that. On our 52" deep pool the water level is normally at 48". The best way to figure volume is to actually measure the water depth and figure from there. By the way, close counts!

    For a 15' X 30' X 4' rectangular pool I get 13,500 US Gallons. I think that's the number you should start at. You can always adjust that number if you find out that the PC (pool Calc) recommended additions don't work out right.

    Re: Not sure what I have with the house I bought.

    Ok folks, thanks for all the help so far.

    I'm going to go with 13,500 gallons for now.
    The suction pipe, that comes from the skimmer basket, is 2". The return, that comes out of the sand filter is 1.5".

    I've included some pics:
    http://mark.phillk.net/gallery2/v/mk...ew+House/Pool/

    PIC_0182 shows the skimmer pipe (at the far end of the pool, far from the pump). There is some sort of connector shown there, I can't tell if it's a Union or Check Valve. Any thoughts?

    What can you folks tell me from the pics?

    Re: Not sure what I have with the house I bought.

    I can tell that you have a multi-tool and one big honking pool!

    I assume that's the filter under the plastic bag. That's a union in the skimmer line. You probably need to drain some of the water off the cover with a hose or submersible pump. Can't tell much beyond that.
