Just had my local pool store install install a new Hayward MaxFlo VS 500 pump to pair up with my existing Hayward DE3620 filter. The tech was there only to install the pump and get the system started. I decided to go with the local purchase instead of buying online since the price after the rebate from the electric company was same, the warranty is extended to 3 years, and the electric company wont honor the rebate unless purchased and installed from a specific list of local retailers. A few days prior I opened the filter and completely cleaned the grids. I inspected the best I could and did not see any rips on the grids and no cracks on the manifold.
So after the pump was installed, the tech started it up and we dumped the 4.5lbs of DE in the skimmer. The returns were clear and no DE was coming back into the pool. I recall the tech going back to the filter, cracking the air relief valve and after a minute or two, steady water was coming out and he closed the valve. After that he was on his way.
I just opened the pool yesterday and the water is clear but there was a lot of dirt and leaves on the floor. I turned the pump off, setup the vacuum and vacuumed to waste (took about 45 min to vacuum). I had to empty the filter basket twice because it was full. I decided to backwash about 2 minutes (which was unnecessary but I wanted to play with the pump settings), kill the pump, switch to rinse for 20 seconds, kill the pump then switch to filter and proceed with adding new DE (straight from the Hayward filter manual). Again, no DE was coming through the returns.
So I tried to vent the air from the filter 2 ways (first keeping the valve open before starting the pump and second, keeping the valve closed before starting the pump) and both times after the air has vented, I did NOT get a steady stream of water ONLY. But rather a slurry of DE water coming from the vent. But no DE is coming out the returns. When the slurry water/DE mix comes out the vent and I attempt to close the valve, the DE builds up in the threads and I cant get valve to seat properly which causes air to leak out. Why am I seeing DE coming out the valve?
Some questions.....
1)What is the right way......Are you supposed to have the air relief valve open or closed before you start the pump when adding new DE?
2)I'm under the impression that every time you open the system you should bleed of the air? Is this correct?
3)These are the pump settings the tech setup.
Timer 1
8:15a to 9:15a 7 days 2925rpm
Timer 2
6:15p to 7:15p 7 days 2925rpm
Timer 3 (I dont feel any water coming out the returns)
12:00am to 11:00pm 7 days 1000rpm
Is this sufficient?
4)I have yet to see the pump completely fill with water. On the low setting the the filter basket barely has any water in it. When I manually switch the pump to the high speed, the filter basket is never completely full but the stream of water coming out the returns is very strong. I recall my previos pump was always full with water.
Thanks
