We have a hard freeze going on here in Dallas and I noticed we started losing water in the pool. Traced it down to the connection where the pipe for the waterfall connects to the spillway. It has a threaded connection. Waterfalls have been running constantly since Friday with the freeze protection on. Does that connection need to be spun tighter or do I need to wait until it warms up in two days to shut down the waterfall pump? Thanks for the advice!
