My spa height is about 2 feet above ground and when I clean the filter by shutting off the system, closing the intake valves, and removing the filter housing... The water continues to flow back from the spa through the heater and into the bottom filter housing. Its not a huge problem, but with water that continues to flow back into the bottom, it makes it hard to fully clean out the housing. I was thinking about putting something between the filter and the heater and was curious if I should use a ball valve or check valve and if a check valve, which type? TIA
Ball Valve, Swing Check, or Spring Check to prevent backflow

Spring check. Never use a valve that can be manually closed on the output side of the plumbing. You will manually forget to open it, deadhead the pump and cause damage.
