I am wanting to use the large water tanks for the garden which I think is connected to a downstairs toilet..?
My first question is;
Since the tanks have been at the rented property before we started renting (over 5 years), should I test the water in the tank , which is 90% full, or just completely drain out and start again?
2nd question;
I would like to connect a garden hose to the pump to use on garden/lawns and do not have a clue where to start ..???
