I just bought a new place with an in-ground pool 2 weeks ago. (pool is around 27,000gallons) 38.5x17 rectangle (rounded corners) with a 3ft shallow, 8ft deep.
Upon the first heavy rain storm I wasn’t really sure what to add, chlorine was down so I added chlorine and ½ a jug of 5% algaecide.
I then shut the pump off, cleaned out the skimmer at the pump. Filled it with water and turned the pump on. At this point I realized I had to fill the basket a few times to get the pump to “prime”. Went with my business not knowing what im doing. Bam 1/2hr later the pool was full of foam. My father came over to show me some things and right away was like “Wow put enough algaecide in there”. That night I backwashed out about 2-3inches and filled the pool up to dilute it, and skimmed the top of the water
Next afternoon the pool was perfect. This was 1 week ago. Just maintained the chlorine and have vacuumed the pool since.
So Last night I shut the pump off, opened the skimmer lid, cleaned the basket, tossed water in, turned the pump on.
I jumped in the pool and noticed a lot of air bubbles etc. kept opening the skimmer adding water etc. Come out 1hr later to make sure the pump wasn’t running dry and notice this **** foam everywhere again! So skimmed off it etc.
Now Obviously I am missing a step when pulling the strainer basket out.
The only “valve: I have going into the basket is the Multiport. 2 Lines run into it. there is PORT 1 on the one line, PORT 2 on the Other. I can turn the dial anywhere in between to mix them and turn it to OFF. Am I suppose to be closing this prior to pulling the basket? Then filling it, turning the pump on then putting it back to my ½ port 1&2 setting?
There is no Pressure relief valve on the top of the sand filter either.
Thanks for any help. I have a big house warming in 3 days and want a nice looking pool!
