Ok,so my grandma has a cistern that's been out of service for years.MY dad says that it only need a bomb de ague,but when the lights go out so does the pump hence he prefers to get a tinaco instead.Shouldn't un inversor or planta keep the water pump running?? I don't like the tinaco idea because we'll have to bargain with the 3rd floor neighbors and I here sue son jodones and won't agree with the tinaco.My father also says the problem with the cisterna is that water stays ice cold.Inputs please,thank you.She lives in Alma Rosa
