With no autofill, the water level lowers over time due to the RDF cycling as well as evaporation. As the pond water level lowers, the water level in the RDF also lowers, and continues to use less and less of the drum to catch debris.
As a result, less drum surface area means faster clogging means more cycles for the RDF. More cycles mean more wear and tear on the parts. I would recommend some sort of autofill or trickle system with overflow to keep the pond level consistent.
This is true if you are using pond-water for the RDF spray bar, which I do in the winter time and have to top off the pond weekly. Once past pipe freezing time I use an external water supply from the house and the opposite happens so I use a pond-over-flow pipe in my skimmer.

So rdf s dont come with a water levelor ? i figured since the rdf uses a water from your home to spray off the drum that maybe they would also have a levelor inside rdf.
I did not have one for my Blue Eco nor do I have any for the Red Labels. I opted for a flow through system on the Blue Eco and took the waste tray lid off as my over flow. For the Red Label RDF’s I set up a flow through system and have an adjustable over flow so I can raise and lower the water level.
Ok thanks all
Has anyone had any expiereince with installing tprs in a bowl shaped pond . Since i am not using block or cement for walls the sides are not straight top to bottom they are tapered wider at the top , so if i make them flush with dirt sides they will be aiming up towards surface and if i put them in where they should be the top of the tprs woud not be in dirt and liner would lay on top of 2 inch pvc connected to tpr i could pack dirt on top of pipe sticking out of dirt but i did that on my old pond and had a rip in liner at that point from water weight pushing on it. Any suggestions ?
You could probably use the https://www.dreampond.com/tangential...urn-1-1-2.html type TPR with the flange and twist it to give you the angle that you need.

Thanks Rich but thats exactly what i have in 2 inch but the more i aim it towards the floor or even parallel to floor the top of pvc pipe and flange are not covered by the dirt side wall.
I kind of cut the dirt from under mine and then cut the pipe back a little to make it more vertical with the dirt. Or you can build
the dirt up around the high side to fill in the gap, and then either way, pack the dirt (or mix the dirt with a little cement) really
well. Then when I filled with water I filled up over where the tpr would go so it would force the liner up against the flange and
compress anything that might move... then I drained the water out under the flange to cut the liner. I just tried to leave a little
extra liner in case it needed to settle anymore.
