I love this forum. Here's a slightly different kind of pool problem.
I live in a high risk fire area. Three years ago a fire swept through, and destroyed 32 out of 200 homes in the area. My next door neighbor's house burned to the ground. I was lucky, mine survived with very little damage. After that experience I became very committed to making my house as fireproof as possible.
One of the things I did was install a 2" sprinkler line on the hillside behind my house. There are 10 sprinklers about 50' down the hillside mounted 6' off the ground. All I have to do is turn a valve, and my 2 hp pool pump starts pumping the water from my pool to the sprinkler line. The system works great. It can dump about 5000 gallons per hour onto the hillside behind my house. I figure if I have to evacuate again, I can turn it on and leave.
It does have the disadvantage that if the power fails it won't work, but all of our utilities are underground, so I'm not too worried about that. Plus the entire 300' sprinkler line cost me about $300, so I consider it cheap insurance.
I need to make sure that I'm only drawing water from the deep end drain, and not from the pool vac inlet, or the skimmer (so I can utilize all 22k gallons of water in my pool). I have a valve that controls the amount of suction between the pool vac and the skimmer, so the pool vac inlet is easy to turn off.
I have a skimmer with two inlets in the bottom. My understanding is one goes to the main drain, and the other goes to the equipment. I believe what I need to do is somehow connect the two skimmer inlets together. Does this sound right?
I was thinking I could build a little u shaped pipe with some kind of quick disconnect fittings. The problem is the two threaded holes in the bottom of the skimmer are only about an inch apart, so there's not enough room for that.
Any ideas? Does somebody already make a product to do this? Maybe just a length of flexible pool vac hose would do the trick.
