Like many other cities ours requires the installation of a p-trap on our sewer drain at the time the pool is built, even though we are using a cartridge filter. We won't have a drain line running from the pool equipment, just a spot that we can run a hose to when we need to pump water out of the pool. I will include a picture below. (In the pic the p-trap portion has been left uncovered until the city inspection.
I have a few questions about this:
1. Do folks tend to leave the tops of these uncovered when not in use? (I'm thinking about debris or critters that could end up in the pipe.)
2. I know the purpose of the p-trap is to prevent sewage fumes from wafting out of the pipe. However, if the pipe is rarely used any water at the bottom of the p-trap will evaporate and we will have sewage fumes in the front yard unless we replenish the water at the bottom of the trap. Do I need to periodically put a little water down the pipe to take care of this?
3. I'm leaning toward putting a cap on this pipe and sealing it when not in use. Any reason not to do this?
