Brand New Polaris 380 Weak Backup Pressure

[nazran]

Installed my new Polaris 380. I am not sure if I just need to tweak it or I have a real problem. I replaced a Letro Legend II? that was 15 years old

1. I used the blue plastic flow thing in the wall fitting.
2. I got exactly 28 RPM on the wheel speed test.
3. My hose is a bit too long (2ft) I wanted to make sure I was a little over as opposed to too short. (I will adjust this more)
4. My thruster is towards 11 o'clock
5. It seems to climb the wall REAL well, so much so that as it turns around the tail does spray out of the pool (seemed excessive?)
6. The problem I noticed right away is it got stuck on my stairs. After 3 minutes of this I was thinking... why hasn't it moved.
7. I got down in the shallow end and brought the backup valve out of the water and when it engaged the pressure seemed weak. There is a little trickle of water when it is not engaged but my old valve did that too.

Think I should take the valve off my old cleaner and try it or do I need to run the red plastic wall fitting ( I am at work not sure which one is more restrictive)

Come to think of it... I am not sure there was a head float on it when i put it in the pool.... maybe i left it in the box?

Was not the Head Float... it was installed.

but reading some posts about the head float needs to be pushed in on a new Polaris? I'll check that

Just updating... it was a bad backup valve. I plugged my old cleaner back up valve in to the new polaris and it started behaving properly.

The new backup valve was faulty?
I have an older 280 and nothing comes out (tiny trickle maybe) of my backup valve when its not engaged.

Yeah the new one was faulty. Nothing obvious to me externally. I held the new (bad one) up out of water and it was like a water hose nozzle set to full rather than stream. Connected my old working valve and when I held it out of the water it was like a jet stream and was shooting a lot farther.
