Introduction: Self Filling Water Bowl

Picture of Self Filling Water Bowl

This instructable  stems from my being lazy and my very large dog that drinks lots of water.  I doubt this idea would scale down for a small dog but it works great for for 5 gal buckets.  The photos i have taken are actually from disassembling and cleaning a water bowl that i have used for over 3 years.  This is a pretty simple build.

Step 1:

Picture of

Components:
Galvanized tub (about 5 gal)
Diaphragm style toilet bowl filler
12" toilet bowl supply line
brass garden hose female fitting with 1/2 male barb
1/2 to 3/4 inch hose clamp

Tools:
Power drill and 7/8 bit
knife
screw driver

Step 2:

Drill a hole in the side of the tub, so that the diaphragm on the filler sits as low as possible.  For me this was about 3 inches up from the bottom.  I used an old junk 7/8 spade bit.  It would probably help to clamp a scrap of wood to the inside of the bucket, but i was able to punch it though just fine.  Also a file to clean up the edge would help if there are any barbs.

Step 3:

Simply mount the diaphragm filler in the hole with the diaphragm facing down.  I found it best to use the rubber seal with the kit on the inside of the tub.  Just cinch it down until its tight.

Step 4:

Take the supply line and cut off the compression fitting.  Then slide on the hose clamp and work the barbed fitting into the cut off tube.  Its a pretty tight fit so it takes some work.  Tighten up the hose clamp to hold it in place.  Screw the plastic end into tub and the brass end into a garden hose.

Step 5:

Turn on the water.  when the bowl gets close to full use the adjusting screw on the valve to get the water level just right.  With a little tweaking  you can get the bowl to fill right to the edge without overflowing.  I will go out once a week and tip the bucket over just rinse it out and get all fresh water but other than that i never mess with it.  3 years and still working great!

You can skip the garden hose adapter and hose clamp if you use a compression diswasher adapter. Proline CP 158nl (3/8 in OD Cmp x 3/4 in FGH). Works like a charm I could not find a toilet supply line large enough to accomodate a garden hose adapter, but this works great. http://www.lowes.com/pd/BrassCraft-3-4-in-x-3-8-in...

Ingenious, the price is right, and easy to access parts!

I would love to plumb this inside my house. Maybe use either the shower water supply (which is currently exposed in my bathroom, sigh...), or the toilet water supply!

Good idea. I was recently thinking about an idea like this while visiting my sister and her new pup. I was leaning towards using a level sensor and a valve. I wouldn't have thought to use toilet parts. Very cool.
