Hi everyone, we bought a house with the pool few months ago. Recently the wall fitting for the cleaner got broken. I bought a new one on Amazon and was not smart enough to keep the old pressure relieve valve. After I installed new connected with the new valve, I have noticed that pressure relieve valve is gushing a lot of water and cleaner runs much slower than it was. Checked everything few time - don't see any defects. Water is gushing from under the valve cap. Given that noting else has changed in the system, the only thought that comes to my mind is that the spring on the valve is too weak and valve opens and a lower pressure than the previous one. Was wondering if anyone experienced something similar or knows what pressure cleaner should operate under.

Did you buy OEM or aftermarket? It makes a difference with those parts.

Have you tried tightening the pressure valve cap? See whether you can hand tighten it. If it's already pretty tight, you can try a pliers very gently.

Fully tightened using wrench. However I am not 100% how tightening impacts the relieve. If I understand the principle, water pressure pushes the black cap against the spring.If that is correct I am not sure how level of tightening impacts the opening pressure.

If the cap is not fully tightened, water can escape from around it. This is as designed to allow the user to optimize the pressure going to the cleaner.

Tightening or loosening that cap determines how much water is released. More pressure on the spring means harder to open the valve.
 
I got a new "proper" Polaris valve. After installation no water is being pushed through the valve anymore. So, the cheap valve I bough on Amazon was bad (while was described as a proper valve for the cleaner I have). Thanks everyone for advice.
