Why Siphon Aid?

Now you can 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 re-purposed 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 

There is a 3rd option which requires re-plumbing

your bathroom which can be very costly AND 

will require getting permits - good luck with that.

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.

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!

 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 . . . .

  • 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.

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.
