Im very lost and hoping someone can shed some light on my issue. I have done endless research and spent a little to much money and need some help.
Issue My AO Smith B2848 HP=1 SF=1.65 Died and ceased.
A friend of mine had filled his pool in because he was tired of it after 15 years gave me a pump and motor he had just sitting around doing nothing. This pump is a AO Smith 2853 HP=1 SF=-1.25 and is in great shape and came with a SP-3200 Series pump. After re-plumbing the inlet pipe to the new motor and pump and replacing the lid seal and even putting silicone at all of the joints to make sure there is no leaks the pump will not filly prime and will only put out 10psi to my filter.
Now where things get interesting. There are not leaks of any kind that I can find. Also when I turn off the pump it holds a seal and no water is lost and no extra air comes into the pump. I can then turn on the pump again and it starts working right as it was. Before my pump died it would put out 15psi and the pump would prime with no issue. The Pump was old and didnt look in good shape so I opted for the new pump on the new motor.
I spoke to a few Pool stores and even had one come out. They informed me that the new motor I got just didn't have the correct amount of power. They informed me to get another 2848 or 2858. So I looked around in my area and a 2858 was local and a good price brand new. After installing the new 2858 HP=1.5 SF=1.5 motor on the Hayward SP-3200 I get the same result that the pump will not fully prime. But now my PSI went up to 15psi. Again when I turn the pump off it holds a seal.
Other information about the pool. Impeller is clean no debri, Piping is 1.5", only a skimmer no bottom drain, Liner pool, 18,00 gallons, and salt water pool.
I know nothing about the impellers. Thought it may be that that's why Im now reaching out TFP.
Thank you anyone for advice.
