Have a look at the steam holes in the bottom, they should be nice an clean with no blockage. If they are blocked up you will need to remove the calcium buildup inside the iron. Get some LimeAway at HDepot, pour it into the water reservoir, let sit overnight. Next day turn the iron on and try steaming on some old papers covered with an old rag or towel, once it starts working steam for a few minutes, then unplug, drain it, put in clean distilled water and flush it out until the steam comes out clear. Use distilled water not tap water, it has much less mineral content and will be less likely to plug it up. Most pharmacies and Walmart sell distilled water. ! gallon about $1.25.

Irons heat up to 410° on the cotton setting.  If yours is leaking, it could be the sealant from inside.  If it was ever repaired, the wrong type of sealer was used.  If it wasn't repaired, it is overheating and needs repaired or replaced.

I'm not sure of your question. An iron has a small funnel shaped hole. That is where the water goes. Some irons have a sight glass that tells you how much water is in the iron. Use ditilled water in an iron to prevent build-up of mineral deposits which can clog the iron.
