Increasing grey water capacity
« on: April 01, 2016, 10:12:28 AM »
Hi,
I have a 12 gal. grey water tank on my HW27SC which is too small. I wish to increase my capacity. Has anyone used some type of pump to transfer the grey water to another type of tank in their pickup bed? The black water tank is also 12 gal, but doable and I am trying to avoid the totes.
Thanks for any input.

I rented a HW27KS last month...it had a hose fitting for the grey water drain.  Is yours the same?  If so, I should be pretty easy to rig up a pump for that application...pretty much any self priming pump that will lift a column of water 8' or so would do.  Just make sure to not use it for fresh water later! :o

Many have "Blue boy" totes.. which work great for that, They come in 5,10,15,20 and larger sizes (30,40 and more as I recall)

The 5 is luggable, the 10 has wheels and you can drag it th 15 has an optional hitch adapter (Which I modified to fit the 10) I think the adapter is also used on the 20 (kind of a fork thing) and larger than that the hitch adapter (fits a ball hitch) is built in.

Fill it, Hook up, drive to the dump station and waste away.

Or you could get one of these to put on the end of your sewer pipe then use the pump as stated above.  What would you have in the truck? A 50 gallon  drum?

When we had a pop-up, I carried two 5 gallon jugs and used them to empty the gray water tank. It had a garden hose fitting, so I used a 90 degree elbow to fill the jugs.

It may not sound like much, but 10 gallons is a lot of gray water in a pop-up.

I agree that a tote tank is the logical route, but you could pump it if you feel so inclined. I would use a transfer pump like this one from Home Depot , tied to the adapter that Rene linked to.

Or find a water pump out of a junked RV. There are plenty around. Give the guy $5.00 if it works.

Thanks for the suggestions.  I have the 3" to garden hose adapter, and will have a 25 gallon drum in the truck.  Trying to find the best kind of 12V pump, thinking that a diaphram pump as opposed to a impeller type would be better due to particulate matter in the grey water.  Anyone have any experience with this or suggestions?
Thanks,

Before you make up the hose to the end cap, install one of these.  It will stop any particles from entering the pump.

I would still recommend a transfer pump, but a normal RV demand pump such as the common shurflo would work as well. I think I'd go with a larger strainer basket like this over a hose washer screen.

Most certainly easier to clean...

when we were popping up, I used an aquatainer, approx 5 gallons.

Usually it was pretty much hand washing with a bit of tooth brushing waste, and since we were in the wood (state park) I would usually take it out to some bushes off path, and distribute it.... yeah, I know, not supposed to.  Hopefully I've crossed teh statute of limitations...

before the aquatainer, I used a 5 gallon bucket that had some mysterious weep holes in the bottom...???

Over on a popup forum I used to frequent this was often discussed.  One guy came up with a way of venting one aquatainer into a second one, so that when teh first one filled it would overflow into the second. He had a small 12VDC pump rigged up to transfer water up into his truck, etc...

On another note, i have considered adding a second grey tank under my MH, by teeing into the drain pipe and hanging the tank in an open area the drain pipe runs through.  The only thing I never sufficiently figured out was how to vent it.  Eventually I dismissed it as too much work.

I do not think that type of pump woudl work well in that application

Drill pumps (Simple rotary pumps that you drive with a hand power drill) might work better.


For a 12 gallon Gray tank, and no black tank, I say a 15 Gallon Blue Boy tote with towing fork is the way to go.. Bigger get kind of pricy.

Well I started my project.  Would like to post photos but not sure how to do it but I'll try.  Attachments limited to 350KB.  Anybody know how that equates to megapixels for photos?

1 megapixel is a bit less than 1Mb file size.

640x400 pixels equals (wait for it ...) 256,000 pixels or 250 KB (1024 pixels per KB). That's a good size to display on almost everyone's screen and should upload OK, especially if they're saved in JPEG format.

Try selecting email if your camera has that option, or load the image into Paint and use it's Resize function to reduce it's size.

Since most picture files are compressed, e.g. JPG or PNG format, the actual file size will typically be much less than what Lou describes. A typical 640x480 picture is often only 30-40 KB in size. I have photos with resolutions in the 2000 x 1500 range that are only about 275 kb in size. though most are somewhat larger.

2048 x 1536 = 3.1 megapixels. Depending on the subject matter and degree of compression, the resulting file could be anywhere from 200 KB to almost 20 MB. There are numerous free tools available for compressing files to any desired degree and some even let you specify the target file size. The compression tools can either be installed on your computer or run via a website such as http://compressjpeg.com/

This is a photo test. I got this barrel from a car wash, it was used for soap.  Made a cradle for it from 3/4" plywood and lattice strips.

Nice!  I did something similar with a couple of 50 gallon barrels and some pallet wood.

If you want to use a barrel to transport waste, the fine thread bung is standard 2" pipe thread.  You can use standard PVC fittings to bring this up to 3" PVC and mate to a standard RV dump valve and sewer hose connector.

I used a macerator and hose to fill the barrel through the coarse thread bung on top, then transported it to the dump station and dumped it like an RV tank using the dump valve and hose on the fine thread outlet.

I use a macerator like this one to pump my waste water into a blue boy in my truck bed. It's been working great for 9 years now.

I am familiar with the flo-jet but did not want to spend that much.  Below is what I wound up with.  Works great with fresh water, have not had a chance to try it out while camping.

Sorry about the link.  I can click on it and it opens, or highlight it and open in a new window and it opens.  Don't know what the problem might be.

When I try, (a couple of different ways) it wants me to sign in to Google. I guess that's what others are seeing also. Most of us would rather see the pic posted on the site, rather than click on external link. One really doesn't have a clue what the link really is until we click on it and then it can be too late.

I understand. I did not have that issue as I guess I was already signed into google.  Will try something else, just not familiar with the process.

Here are some additional photos, hope they work.  There must be an easier way than having to select each photo individually.  Still learning, thanks for  your suggestions and patience.
