I wonder if anyone has installed a check valve on the return pipe? I am interested in: 1. Does it reduce flow power? 2. Does the ball valve rattle when water passes through? 3. Which is better, a ball or a spring valve? Thank you.

Reduces, clogs. It was rattling with a spring.

I also installed a regular spring hydraulic valve. It didn't rattle, but the flow decreased and it got clogged. In the end, I gave up and installed a faucet - I close it manually when needed.

Well, it didn't work out to be the smartest. Last night the power went out, and the aquarium started draining excess water into the sump with such a noise that I panicked and rushed for mops, buckets, and rags. I thought my heart would stop. There's always that thought in the back of your mind... "WHAT IF IT BURSTS OR LEAKS!!"

Hello! The check valve has been in place for four months and has never let me down (even though the SAM is made with a margin). I threw away the spring. Your controller was placed in a food container a week ago. The SAM has been covered with acrylic glass since day one. Two coolers are working. The first one, 80mm, is running at half power, blowing air over the algae reactor - around the clock. The second one, on the side wall, is 120mm and operates on a mechanical timer for one hour, 15 minutes at a time (except at night, so it doesn't disturb my sleep). There has been no condensation...

Thank you for the information, then I will install a non-spring check valve after all. Now we cover everything with liquid plastic after assembly. We check the operation right next to the bubbling SAMP. It is assumed that the contact pads will all rot within a couple of months, but all the other electronics will remain intact.

So, the thing is... Today, a check valve was installed on the return pipe. There is only one advantage to this solution. The water level in the aquarium remains unchanged when the pump is turned off. Disadvantages: 1. The ball rattles at any pressure. 2. The return water pressure has significantly decreased. 3. The return part of the system has become inconvenient to maintain. The valve was dismantled and nailed to the wall as a symbol of disbelief in others' mistakes.

The fewer nodes in the system, the more reliable it is!!!
