Question:

My hoses are 1/2", and the filler tube is a little over an inch. Is the item with the cap next to the cement in the picture you sent the fitting for the filler tube? If so, is that the right size to fit what I think is a standard green and white water filler hose?

Helpful Expert Reply:

I've attached the fresh water fittings page so you can get the connections you need. I unfortunately can't give you parts without knowing the hose measurements and the tank measurements. For instance it looks like you will need the Valterra ABS Tank Fill Kit with Threaded Cap # RK909, but that kit comes with 2 elbow adapters and it looks like your current kit only has one elbow adapter.

We have 1/2 inch, 3/8 inch, and 1/4 inch straight fittings and the same in elbow adapter fittings. I've attached the page to our parts to assist.

For your system I recommend the Valterra Male Adapter - 3/8" MPT x 1/2" Barb - Polypropelene # RF840 for your 1/2 inch hoses and also the Valterra ABS Tank Fill Kit - Straight Barbed Fill # RK908. This will give you the cement and the fill you need as well as the drain nuts that will be required for your fittings if the new water tank does not have the threaded fittings for the hose adapters or the drain plug.
