Hi all, just opened a new Polaris 380 today and have spent all day tinkering with it trying to get it to work without much success. Water seems to be flowing as it is supposed to, but I am not getting enough rpm’s from the tires and it is constantly getting stuck against walls or in the angled corners at the deep end, typically only running for 5 minutes or less before it stops. The backup valve will sometimes get it to back away from the wall but not enough to change its course, it will drive straight back in. It will also get stuck in the deep end with the rear wheel off the ground and it will just float there and not move. I trimmed the hoses as prescribed, have tried different settings for the thrust. I tried removing the blue disc from
The connection port to improve rpm’s but it made things worse. I feel a lot of water coming out from the pressure release valve, not sure if the issue is coming from that? Any tips I can try before I send this thing back?
 
You need to get the RPMs right. That's step one. If the RPMs are not in the correct range, any other changes you make will probably not fix issues.

Water should not be coming out of your pressure relief value under normal operating conditions. You probably need to tighten it. The flat-ish part where you probably see the water escaping can be screwed tighter. Or possibly, there's an issue with the spring inside the valve (that keeps it shut except when very high pressure is experienced)

Did you have a Polaris prior to this new one? Was it the same model? If you replaced with the same model, you will probably need to put the blue disk back in after tightening the pressure relief valve.

Silly question, but you do have a booster pump on this? Are you getting plenty of pressure out of the UWF? Are there any restrictions in the feed hose? Is water leaking out of the water management system inside, instead of going out of the three jets in the main suction tube?

I have a good amount of flow coming out of the pressure relief valve (which is good and tight) but mine works just fine with this.

Thank you, I took off the pressure relief valve and put it back on and made sure it was good and tight. After that I felt no water coming out but my rpm’s were 17. So I tried again taking the blue disc out of the connection port (before when I did that water was just spilling out of the PRV and it actually made things worse) and this time I only felt a small amount of water out and the RPMs improved to 26 and it seems to be running much better. Need to adjust the thrusters a bit because it seems to want to spend most of its time in the deep end but hopefully we aren’t getting stuck any more.
