Video Transcript for Valterra RV Waste Valve Cap w/ Garden Hose Inlet Review
Today we're gonna be taking a look at the three inch Valterra RV waste valve cap with a garden hose inlet. It's available in clear with part number T1020-1CLRVP and in black with part number T1020-1VP. This is a great replacement for your lost or damaged waste valve cap. If you don't have a garden hose inlet, it can serve as an upgrade. The inlet allows you to connect the flushing hose for all sight drainage of your gray water. The main cap features a Santoprene seal.
So it's gonna be leak proof and the bayonet fitting makes it quick and easy to install. Both caps feature a rubber leash so you can't lose them. Now that we got all the features, I'll go ahead and show you how to get in installed. First thing we'll do is attach the rubber leash to the pin here. This is so we don't lose it.
Once it's connected, we'll attach the bayonet fitting. That's gonna complete our look at the three inch Valterra RV waste valve cap with a garden hose inlet, part number T1020-1CLRVP.

Used these to replace the stock Valterra caps on new camper because I wanted the water hose connections these have. Would have Been 5 stars except these only have two hooks to hold them on where the others have four. Since there are only two hooks; they drip when the water hose attached puts a bit of weight or pressure on the cap. Keeping the hose from pulling on the cap stops the problem.

Have trouble turning them on as knobs on edges are very small. Old ones had 4 clips these only gave 2

The seal on my old cap was cracked so I bought this. The tethers are nice. I like the garden hose hook-up. It makes it easy to flush your tanks without having to run a hose inside the camper and down the sink or toilet. You'll want to grab an adapter for the end of your garden hose to hook up to this though.

The RV waste cap with garden hose hookup worked very well. I was able to fill and sanitize my fresh water tank then run the faucets into my grey water tank and drain it before going on a trip. Seems like a simple feature that all waste caps should have.

The garden hose threads don't fit a hose. Otherwise just fine.

I am sorry to hear this Lester, this issue has not been to our attention before. What kind of garden hose do you have?

Had trouble finding this anywhere else - so glad eTrailer had it available. Our initial order wasn't successful due to external issues. Once we discovered and corrected the problem, I was impressed that eTrailer honored the pricing at the time our original order was placed. Great customer service.

The waste value cap with hose fitting is a great idea BUT isn't exactly plumb. The hose attachment is at approx. 0500 (clock) position, not at 0600. The ears on my setup are at 0300 & 0900.

- Sewer Drain Valve and Hose Needed for Current Drain SystemSince sewage connectors do need a proper seal (typically by using solvent # A05-0303) I do recommend changing out some of your sewage pipes as they are looking a bit rough. It does look like you have a 3" round pipe from your photo so if you were to keep your current system you could possibly use a Fernco rubber sleeve to connect the Valterra Coupling # F02-2025BK to either an extension or to the Valterra Bladex Waste Valve # T50. If you need an extension you will put this waste valve...

- Fittings on Valterra RV Sewer Termination Adapter T1029-4Valterra RV Sewer Termination Adapter # T1029-4 has different fittings on each end. One end is a 3-inch lug fitting that mates with a bayonet-style connector like what is on # T1020-1VP and the other is a 3-inch male pipe thread fitting that threads into your 3-inch female sewer pipe. All RV sewer items are shown on the linked page.
