Hi all, Dawn from PA here. I have been fighting with my pool for about two weeks now, the pool is winning thus far. I have been doing some reading here, but now I think it is time to come forward for help. Circulation is my problem. I drained my 27 foot round pool down to about two inches and started to refill. As soon as possible, started vacuuming and got everything looking pretty good considering how bad it was to start with. So after wading in the muck, getting bitten everywhere, vacuuming and refilling, I was ready for the final before swim vacuum. Now, it seems that I don't have much suction. There is some suction, but it is not adequate for a good vacuum, or to circulate the water properly.
Before starting this endeavor, I replaced a cracked strainer housing on my Hayward Matrix 1 1/2 HP Pump. When I lost suction, I thought perhaps the cover plate on the pump was also cracked. I ordered a new one and installed it. I also replaced the o-rings and lubed them with Leslie's Pool Lube. When I put everything back together, it was more of the same. The pump makes a noise, but not a grinding noise. It makes the noise on the filtration cycle and the Recirc cycle. There is no abnormal noise during the backwash or rinse cycles. Also, the water is continuously churning in the strainer during those two cycles while it begins with a churn and suddenly goes flat in filtration and Recirc. If I put my hand in the skimmer basket, I can feel suction, but only when I am far too close to the hole (ouch, there is a sharp edge in there!). If I look through the lid to the strainer basket, the water just appears to vibrate.
Today I have checked the hose to the pump, the hose from the pump to the filter and the hose from the filter to the pool, all are clear and were tightly in place. A gentleman at the pool store said that perhaps my impeller was cracked. I had already made sure it was not obstructed by debris, but I did not inspect it for cracks. As of right now, my pump is in pieces. I took it apart to the impeller, which from what I can see, is not cracked. I am afraid to take anything further off of this pump. My next step is to attempt to take apart the filter (yikes) unless someone here can steer me in another direction from what I have described.
I have tried to do a prolonged backwash and rinse and backwash and rinse cycle, but it did not improve anything. I replaced a broken pressure gauge and it has been reading at a very 'jumpy' 18. As of right now, my chemicals seem to be good from the pool store readings, but I know that won't last if I do not get the water moving in this pool.
Any and all help greatly appreciated!
