I have a 40,000 gallon, 20 x 40 inground pool. I am replacing the 1996 model filter and 6 way valve. I ordered the same filter brand, same model number that is listed on the old filter. Could technology have advanced since 1996 to the point where the filter tank is considerably smaller? I am thinking that the older filter was mismarked by the manufacturer. Can I have anyone's opinion on this? It just doesn't look right.
Same manufacturer, same model number, difference size...

Don't think you're going to get too many responses if you don't include some basic information like the name of the manufacturer and the model number.......

Welcome to tfp, Tigger883 
As mentioned please post the type, manufacturer, and model number of the filter. Generally, the bigger the effective filter area, the better.

It is a Pentair Tagelus Sand Filter TA/40. I tried to upload the pictures but saying to big. So I will take some again tomorrow in daylight and post it. Thank you for letting me know I needed to post that info. I wasn't thinking.
The pentair TA-40D is a small filter. I am not aware of any change in the effective filter area of the TA-40. Post your pool volume.
The literature says that model is supposed to be approx 19" diameter. Is that the size of your original one or is the new one that size? What is the diameter of the one that is different?
40,000 gallons, 20 x 40...but steps make it 44. I have taken care of this pool since I was a young child. My grandparent's owned it and I bought the homestead 13 years ago. I had the pool renovated and replaced the sand with Zeobrite and the 6 way valve 13 years ago. Pool was covered and unused for 4 years until we bought property. Never had any trouble with this pool or maintenance since using zeobrite. I replaced (or thought I was replacing) the exact filter unit that was put in in 1996. However, the filter that I just received is much smaller in size than the old filter (which has the manufacturer's label attached and that is what I went by when I ordered it). I will post picture tommorrow. Filteration system also have Hayward 1hp "super pump". No trouble with pump.
No, the original is actually 24" in diameter. That is why we are believing the label on the old filter is not marked correctly. The new one I just purchased is much smaller.
That is why I asked if technology may have advanced in the past 18 years...where Pentair redesigned the tank possibly.
No, I don't think sand filter technology has changed so that a new 19" could perform as well as an old 24". The model 60 would have been a 24". Love to see a closeup photo of the 1996's filter label.
Picture 2 of 1996 Pentair Tagelus label. I've done my research and I am thinking label was clearly mismarked after I received the new replacement Tagelus and seen the size difference. I do not want to install a new filter that will obviously not keep my pool clean. I believe the old one is a 60. Anyone's opinion would be very much appreciated. Thank you.

IF you don't mind answering - why are you replacing the filter ? unless there is a leak / split seam - I would not be changing out a working filter just for the sake of "change".
Replacing it due to leakage at the top of the filter tank neck....part can not be taken off and replaced. It is permanently attached. Some of the laterals bad, and I needed new spider gasket etc. Old filter started throwing filter media back into the pool. Easier to switch out.
