i have an above ground pool and can't get the heater to ignite, my ignitor came off during the winter and can't seem to find where to light it myself to get the pilot light on. checked the manual and no luck. would love some help and if possible to dumb donw the instruction as in please no follow this pipe to etc.

I am a civil engineer. As such, I expect the same degree of perfection as is generally expected in my work. Ihave a 20 x 40 above ground pool which has been up for about five years. The initial installation of the pool went badly. The pool was not setup in the specified spot and misaligned with the side of my house. Rather than take down the pool and start over, the installers moved the main supports by sliding them in the sand base and repacking the sand. The rest of the construction went down hill from that point on. The decks and railing did no fit and alot of pushing shimming and jiggling was required to make things fit. This created soft pockets in the sand base under the liner that were not apparent until they filled the pool. The weight of the water compacted the sand making depressions in the liner on the pool floor. The installers refused to remedy this problem. They claimed that it was not uncommon and it didn't pose any risk of breaking the liner. I ran them off, only paid half the contracted price, and never heard from them again. The depressions seem to be getting worse every year. Some are about the size of tennis ball and just as deep. I don't have any leaks yet, but I am concerned. It costs about $1000 to fill my pool. Is there a way to fill the voids in the sand without draining the pool? Any advice would be greatly appreciated.
