I purchased a home here in sunny Sanford, Florida two years ago in 2011. It had been foreclosed and was a serious fixer-upper. There is a screened in rectangular pool in the back that is about 4 feet deep in the shallow end and 8 feet deep in the deep end, in ground, gunite, around 24000 gallons. This is the first pool I have owned.
There is a roof mounted heater that is mostly made out of some kind of plastic helicoil like piping. It was leaking in a couple of spots, so I cut and plugged those tubes, and it seems to work for the time being, but I want to fit it right. There is what looks like a vacuum release valve that looks like it should have some sort of cap on it to keep out dirt, but it is missing, so if I push down on in the center of the thing with my finger while the pump is running and the valve is set to the the heater, water comes out rather forcefully. There are some wires that go up to the heater, some appear to be intact and others seem broken.
1. Is there a recommended place to get replacement black plastic hose for the roof mounted heater? I don't really know what the stuff is called, and that might be part of why I am having such a hard time finding it.
2. Where would I get the missing cap? Or is it not a big deal? The valve works if I press it. Initially it seemed like it had sand/debris stuck in it keeping it open and it was leaking. I opened it all the way and flushed it and that seemed to fix the problem for the time being, but I'd like to fix it right.
3. Wiring. Being that this was a foreclosure, it didn't exactly come with instruction manuals. I have a controller box mounted near the pump with a temperature dial, and I think two sets of wires coming out of it. One set goes to a valve. That works. If I turn the switch on or off, the valve rotates appropriately to either allow flow to the roof or not. The other set of wire seems to go to the roof. I think this set is broken. My thought is this must be some sort of thermostat which measures the temperature of the water and shuts the valve off when the temperature is reached. Is that right? Is there anything else to this? Can I just run new wire, or splice the existing broken parts? How can I effectively test the thermostat to make sure the system is working?
