Welcome to affordable water conservation

Do you want to save water?
Conserving natural resources is never a bad idea.
What if you could use your Bathwater for your flowers!
Reusing bathwater could save you water and money.
Bathwater and laundry water are sometimes called gray water or water that has not been used for sanity (toilet) purposes. For this reason gray water can be usually be repurposed for use as irrigation or landscape water.
The SiphonAid is a simple device used for Bath to Landscape gray water reuse.

A Gray Water Bath to Landscape System may help
There are two ways to move your bath/shower water outside
1. A bucket
2.  A siphon
The SiphonAid can make siphoning with a garden hose quick and easy.

Bath Water, including shower water captured in the bathtub, can be siphoned to shrubs, bushes and trees in an easy and cost effective manner and your plants will benefit from it.

Use only when plants are thirsty.

It pays for itself in water saved, uses no energy!
Use your bath tub like an indoor rain barrel.

Saving water is one way to live sustainably.  A sustainable lifestyle benefits everyone. 

Bath to Landscape (B2L) using a SiphonAid is a very cost-effective gray water system.  B2L gray water using a SiphonAid can be a good alternative to more expensive gray water systems. SiphonAid is sensible conservation tool. No expensive plumbing or parts – use your existing garden hose.

Every bath tub can be a “rain barrel” – and every bath tub user can benefit by having a SiphonAid handy.  Use it whenever your outside landscape is dry, just save that bath/shower water.

There may be no need to use your SiphonAid every day – just when you have sufficient water saved in the tub and when your landscape outside needs water. Another tool like the old standby toilet plunger, the SiphonAid may not be used every day but when you need it – it is good to have on hand.

The SiphonAid is a “high tech” alternative to the bucket.


SiphonAid is optimal during dry seasons as over watering in rainy times may not be practical. It is not difficult to save bath/shower water in the tub and siphon it out to thirsty plants.  Watch the video . . . .

This is a product for your customers that will allow them to save appreciable amounts of water. This is sold to agencies for distribution as a water saving tool to allow your customers to recycle their bathwater (gray water) for use on appropriate landscapes.
  • Green! Uses NO pumps or electricity.
  • Easy to use!
  • No construction – no re-plumbing – nothing to get permitted.*
  • The most cost-effective means of saving water in the average household.
  • Your bathtub is a valuable resource. Like an indoor rain barrel it can be used to collect grey water.
  • For water suppliers to use as a useful means of promoting water conservation.
  • The most cost effective water saving element your water agency/company can use.

The Siphon-Aid™ is designed as a Gray Water system that allows the user to easily transfer everyday bath/shower water outside for use in watering landscape bushes, flowers and trees. This is not a plumbing product but a handy household device!  


            Important Operating Instructions

    From time to time people say that “their SiphonAid doesn’t work.”    

Under the right circumstances a siphon will always work.  The Law of Physics tells us this.  The product shown here is an “aid” or assistive device to help you create a siphon action – moving the bath water outside to your thirsty plants.

    Here are a few tips to ensure your success.

1. The outside end of the hose should be lower than the bottom of your bathtub; a few inches, several feet – just lower.

2. Make certain there are no kinks or obstructions in the hose.

3. Hold the SiphonAid w/ hose attached to the faucet tightly enough to force the faucet water into the hose.  With a little practice you will learn how long it takes the faucet water to get outside.

4. When you achieve that (here’s the important part) very quickly thrust the SiphonAid and hose into the tub of water.  The water that is already outside has created a suction and if that suction is broken, i.e, air getting into the hose – you will automatically lose your siphon action.  Hydrostatic pressure holds the water but air will cause it to be lost as illustrated by the “water in the straw” demo on the video. 

    So when you get enough water going through the hose from the faucet – QUICKLY – as fast as possible thrust the SiphonAid/hose into the tub water.  That brief millisecond of air will not be enough to break your siphon action.

5. To help you maintain the hydrostatic pressure try to keep the first few feet of hose after the SiphonAid laying in the bottom of the tub.  This will give you a bit more pressure to insure a good siphon action.                                

* Multiple agencies have noted there is no permit required for this household device.  There is no construction involved and no plumbing required.

    It has been brought to our attention that some people cannot operate their SiphonAid because they claim to “have no gravity at their house”.  Be assured that you have an adequate amount of gravity at your home. In the event you have NO gravity at your home, SiphonAid assumes no responsibility.  Check with NASA for assistance with low or no gravity.

    Another problem that sometimes occurs is that people cannot get water to go through the hose.  Check the hose for kinks and/or other blockages.  Water that is siphoned is not under pressure so it flows gently and cannot force itself through a blocked hose.

    The SiphonAid is made in part with rubber.  It is the user’s responsibility to best fit the SiphonAid to the bathtub faucet.  Remember, this is NOT a plumbing device and is not meant to hold itself onto the faucet.  The user must hold the SiphonAid up to the faucet forcing the water to flow through your attached hose.  This will take a few seconds; long enough to get the faucet water going through the hose up and over the window (see the above video).  Quickly drop the SiphonAid and hose into the bottom of the bathtub.  At that time the principal of hydro static pressure along with your gravity will be sufficient to pull your bath water out to your thirsty plants.

    The SiphonAid is meant as a tool useful for occasions when you have a sufficient tub of bath water that you would like to siphon outside.  There may days when you don’t have an adequate amount of water saved in the tub or days when outside plants do not need watering.  The SiphonAid is usually an occasional tool. Like the toilet plunger; you may not use it every day – but it is handy when you need it.
