Hi! Amateur pool owner here that spends lots of time learning from the pros at this site but I’m stumped! Last year, I replaced the sand filter and motor for our abover ground pool. We had a great season with no issues. I followed all the instructions for the winter closing. Upon opening the pool today I started up the filter. Great water flow and intake. Let this run for an hour or so and got ready for the first backwash. The intake is not existent and the water is free flowing out of the waste hose. The rinse and waste cycles work fine. I took off the multiport valve and checked it in both locations (directly under the handle and the entire component. Everything looks clear and operational. Suggestions??? Please help!

Welcome to TFP! 
Let's start with some pics of your filter, its connection, and the overall equipment pad. We might see something right off the bat to help.

Flute-player,
If your MPV is in the "Filter' position and water is coming out of the backwash hose, then the MVP's spider gasket has to be bad.

Please also post a pic of the lines going to your filter and an overall shot of the equipment pad.
Sorry I'm so dense, but I don't understand the problem you are having.. 
Are you saying that when you are in the backwash mode, that you are not getting any flow, or very little flow out of your waste line?
What does "the water is free flowing out of the waste hose" mean?
Thanks,

Your hoses are backwards! I just did the same thing, pool looks to be filtering fine but will only flow with no pressure on backwash. I could be wrong but almost guarantee this is your issue.

Exactly why I was hoping to see some pics to confirm.
Filter, waste, and rinse cycles all function properly. No leaks. My only difficulty is with the backwash cycle.
Understood and I was in the same boat. I found a old post where backwash was a
And it will appear that way just do yourself a favor and make sure "pump" is connected to hose from the pump. If you already checked and all is well disregard but I could not believe I had done it lol. Good luck I'm headed out to sweep mine.

A lot more common than one might think at spring opening. Lots on an owner's mind during the opening process and sometimes the most obvious thing just gets past the eyes.
You guys were right. Backward hoses for the win. Lol. Thanks for your help!

That was my gut feeling earlier. Glad you got it resolved. Now on to more important things.
