Its a simple design bottom is intake water goes through media and gets to pump. I chose to use 1in pvc pipe. Pump already had 1in fittings so I stuck with that. As you can see in pictures the intake has 2 ball valves thats so I can disconnect the union without water siphoning out of either bucket or tubeing. The plumbing to pump kinda had to get more complex to keep it from getting to tall. The pump I have is a lifegard aquatics 3000.
1st leak test showed leaks at 90 elbow on pump, bottom bulk head and gamma lid.
2nd leak test I eliminated all leaks tightened elbow on pump, bought larger rubber seals for bulk heads, and for gamma lid used urethane on inside lip.
At first I thought of making multiple intakes and placing pump inside bucket but I though for a first time it would add to many possible problems.
