    i,m trying to find some kind of gadget that i can hook up to my bathtub drain so that the bathtub water can go into a rain barrel outside, then i can use this water to water my outside plants… any ideas????

      Hi Debra,
      A few challenges, the main one would be your home’s unique plumbing situation; everyone’s is different it seems.

      At first blush, it would seem fairly straight forward to simply hook up a water line from underneath your tub out to the rainbarrel.

      However, what about in the winter (not sure where you reside); you may not be watering outdoor plants because of the snow so what happens to the water from the tub?

      Or what about during the spring and fall rainy seasons when outdoors plants get enough water? What happens to the tub water when the rain barrel is already full?

      So, that leads one to need some sort of manual or automates valve to stop the bath water (or shower water for that matter) from going out to the outdoors rain barrel and instead going down the ‘regular’ water line out of the house.

      I like the concept.

      I am actually at the Delta Faucet Home Improvement / DIY Blogger 2011 event right now. Even though they are into faucets, I’ll ask and see if they know of any products and will let you know (via another comment to this page).

      Thanks for asking!

        Hi Debra,
        I did follow up with the nice people at Delta Faucet today.

        While they focus, as is their name, on faucets, they did say you have to be extremely careful about this.

        Different municipalities, counties, and states have their own environmental laws concerning the piping (e.g. some say it must be a different color for grey water), rules regarding how long the grey water is allowed to sit in the rain barrel to be used because it is not clean or nature delivered (i.e. from rain) water, etc.

        As well, they indicated that some municipalities will charge you for doing this because you are removing water that their municipal water sanitation and distribution utilities would otherwise receive from your home.

        So, if you plan to do this please investigate thoroughly your local bylaws and regulations.

        I hope that helps,

Speak Your Mind
