  1. Pool Pump Filter Size Mis-Match

    in All Swimming Pools Types

    It looks like the crimp is mostly above ground. Here is a bigger picture:

    Thanks,

    So, if I'm understanding you the possible problem would be pressure and not GPM.Yes The HW company only mentioned the GPM as a mis-match. How can I tell what the pressure should be for the filter and if the pump is within that range? That is hard because every system is different(plumbing wise), and pressures will vary between systems. Any where between 10-25 with the filter clean.

    Also, any idea what the squeezed pipe could be caused by. The HW said the pump ran dry and it boiled the water and it melted the pipe.That may be correct! What is the HW going to do about fixing that? That pipe is bringing water from the pool. Between that pipe and the pump is the pumps screen filter. It doesn't make sense to me that nothing would happen to the screen filter (plastic) but would the plastic pipe. Melting point of the pipe is lower than the pump pot. Sometimes the basket(screen) will melt. All depends on how long the pump ran dry.

    Is the melted/squeezed pipe above ground? Or was it unearthed and exposed?

    First, i don't think you could get 100 gpm to that filter, with the size pipe you are using. Now pressure, that's a different story. I think that pressure, not too much flow, is causing the leak. What is the pressure gauge reading when it is running?

    Going buy the graph you provided, you would have to have less than 60 feet of pipe between your pool, and the equipment to get even close to 100gpm. Oh, and this is with NO 90 degree elbows in the plumbing. If you have 90's, tee's, or any other fittings that redirect the flow of water(you do), you have to add distance to your run.

    With 2 inch pipe:

    90 elbow = 5.5 feet

    45 = 2.8 feet

    Tee's = 4.3 feet (line flow)

    12' feet (branch flow)

    You have 12 90's that are above ground, that i can see, not to mention the re-directing that goes on inside the heater. And those are all 1 1/2" 90's that are 4 feet each. Thats 48 feet of head just in fittings, and who knows how many more 90's underground en route to the pool. And don't forget to add the straight pipe.

    Note that these are rough estimates.

    Advise the HWC they need to take a class on hydraulics before commenting on, or denying this type of claim. There are a gazillion system 3's with 1 1/2hp pumps on them on this planet!

    Now to the reality...

    The probable reason that the filter is leaking is that this particular filter is the first generation system 3. Probably at least 15-20 years old (guess), and the tank o ring could be as old. Even an o-ring 5 years old can leak depending how many times it has been taken apart and reassembled. Each time you disassemble, then tighten those hand clamps, you crush the o-ring a little more, and that takes a little form from the oring because it wont rebound(return to its original form) the same when disassembled. Because of this, it will take a little more tightening each time to make it leak proof. Now you get the picture how the o-ring begins to leak.

    If it is the o-ring that is leaking(around the middle of the tank), it is a maintenance issue, and you should probably pay for it.

    Sorry i rambled on, only to tell you in the end that it's on you...

    Good Luck

  3. Pool Pump Filter Size Mis-Match

    I have a cartridge filter system that says the maximum GPM is 100. I have a Sta-Rite 1.5 hp pump. The filter is now leaking and the home warranty company is saying the filter is not designed to handle that size of a pump. How can I figure out how many GPM the pump puts out? The model of the pump is P6E6F-207L. The filter is a System 3.

    In addition, I noticed the 2" conduit from the pool has collapsed. How can this happen?

  4. Help Me Understand My Pool Equipment

    Thanks for the responses and diagram. I do not have a water feature. One thing I'm trying to figure out is how to keep the Spa warm. I'll explain. The pool person put a 60 minute timer on the spa. I have to turn it and the spa heats up and the jets operate. However, when the timer expires the spa heat is then "mixed" with the pool water and quickly cools. I'm not sure why this is happening. I was trying to noodle out where all the pipes go and see if there is a work around. Any ideas?

    Thanks,

    Byron

    This might be what you are looking for, typically the spa suc and spa return are set up on the same side so the actuators (electric Jandy valves) do not have to be re-cammed. Do you have a water feature, I'm wondering what the extra return line is...
