I live in warm climate the Caribbean to exact so my water temp are generally 25-29 degrees all the time. Can I use this developer to develop at such temperatures?
It is important when using this developer to get the temperature down to 20 C, or 68 F. When the temperature is higher it is necessary to greatly shorten the developing time, otherwise the paper can be over developed, and gray out the whites. A little ice can help to lower the temperature.

Does this have to be specially disposed or can it be poured down a regular drain?
From my research, Eco-Pro developer can be poured down the drain. I bring all my used fixer to the dump where it can be disposed of correctly. This developer is fine to go down the drain from my opinion.

question
About how many prints could you make with this before it's exhausted? 5x7 or 8x10 size.
I dont have an exact number to give, however I can say that I have made at least 50 prints (5x7 and 8x10) I never thought to keep count. I have yet to see a change in development time and I have been using it since February. Hope this helps.
