I just had a new pool constructed and started up this week.
Communications with the builder has not been the best, and the turnover was fairly simplistic.
After they left, they said to sweep/scrub the pool daily towards the deep end so that sediment from the plaster work will be drawn into the main drain and filtered out. This is very fine particulate and mostly produces a small cloud when swept. However yesterday being the first day I noticed that there was no visible intake of this cloud or smaller debris that would float right over the main drains. I went to the equipment and noticed that the valves were set so that suction would mostly come from the skimmer with just a small portion from the main drain.
I moved the handle so that it was mostly or all Main Drain, and as I did, the pump began struggling and I noticed that the pump filter pressure gauge fell to nearly zero which to me indicated that there was very little flow. The noise from the pump was very loud (the noise of water being churned with air I suppose as it struggled to suck from the main drain). I checked the returns in the pool and there was a small amount of water flow, so that seems to indicate it is not totally plugged. I then moved the valve back to mostly skimmer.
So my question is: Is this normal? I had a pool in the past and I dont ever recall the pump struggling no matter where it was sucking the water from.
Second question, the pump is running 24 hours a day. The timer is set to the ON position in the over ride. They told me to just scrub scrub scrub and they will check in on me every few days to test the water balance, but in the meantime I have not been able to reach them.
Hoping someone can help me!!!
