Regardless of the capacity of your tanks in Spain, you should always be responsible for their use. For this reason, Maytico has published a series of tips for saving water in homes, specifically in bathrooms.
Choose a shower rather than a bathtub. A shower consumes, on average, a quarter of the water needed for a bath: filling a bathtub requires about 200 liters of water, while a five-minute shower uses about 50 litres.
Install an efficient shower head in the bathroom. Efficient shower heads consume about 6-7 liters of water per minute, compared to 12-15 liters for conventional heads. Its installation is very simple: all you have to do is unscrew the old screws and attach the new ones on the shower hose.
Take control of your shower time. It’s easy to lose track of time in the shower. There are simple and cheap tools, such as a waterproof hourglass, that allow us to know that 4 or 5 minutes have passed.
Turn on the tap only when you need water. While soaping, you can close the tap. Do the same while brushing your teeth or shaving.
Use your toilet cistern well. If your cistern is dual-flow, use the low-flow option when you need less water. It will only use half the amount of water in the tank and achieve the same result.
If hot water is slow to arrive, you can use a bucket or sink to collect the shower water until it is hot. With it you can water plants, scrub floors, etc.
Place the trash can in the bathroom. This way it will be easier to prevent the toilet from being used as a trash can, and you will save water and avoid pollution.
