H2O Tank Issues

[KozVan]

Hi! 

So I bought a water tank ( https://www.amazon.com/Valterra-R8042-Fresh-Water-Tank/dp/B002N5JBVY ) But, It does not have an large port to put water into the tank. The port connections that are there, are female threaded 3/8". 

Please help me with what to get to be able to fill this tank (non-pressurized) from a hose (pressurized).

Thanks!

well you can install your own. that tank is ABS so you just glue a fitting in. however if it was me I would just return it and get a tank with a proper fill inlet, like this one,

there are plenty to choose from on Amazon.

You can easily add ports into a tank with a "uniseal" fitting. You need to start by knowing the diameter of the pipe you are putting into the tank, then purchase the uniseal for that size. The uniseals require a specific size of hole drilled into the tank. A regular hole saw works for that. Then before you put the uniseal in place just rinse out any debris from the drilling. The piece that gets cut out of the tank will stay stuck up inside of the hole saw when you cut it through.

There are many places to purchase Uniseal fittings from but for your convenience here is one company I have purchased them from in the past. https://www.usplastic.com/catalog/item.aspx?itemid=89951&catid=477

I would suggest before you make a purchase you do some research. You can see uniseals being installed in a variety of films posted on youtube. Professional companies do post videos of this process. You will also see quite a lot of them from people who are doing home brewing or doing acquatic farming or chemical storage and such. A lot of uses for tanks with plumbing besides RV uses.

I learned about Uniseal fittings from a local Marine Sanitation Supply store which sells and then customizes tanks with additional ports. Fortunately for me they also stock Uniseals. I needed them for my fresh water and grey water under the sink cabinet tanks. I had purchased the right size and shape of tanks from Amazon, typicallly used for food trucks, but they did not have all the outlets in the location I needed them in. So I have had to adapt using Uniseals. Having spin welded fittings put in would have cost me $30.00 per fitting which was more than an individual tank cost me. So Uniseals were the affordable way to go.

Interestingly enough, I have that H2O tank too lol. Same company, maybe different size tho, and thanks I will have to make the adapter since I cant return tank as its just the right size.

Excellent! TY! I will check for uniseal fittings - I just had no idea what it was even called or anything.

So once I get the uniseal for the inlet to the tank, what should the fill side to the tank look like?
