## Questions & Answers

**Q: Will this fit a whale inlet.**
A: I have an Autosleeper Warwick with the Whale system, this cap fits but is rather tight, I use it regularly with no problem, just hook up and walk away till the tank overflows, cant guarantee it works on other models, but it cetainly works on my one.

**Q: Hi does this fit all Dethleffs Motorhomes?**
A: All I can say is it fits my Carthago (and I seem to remember that is a three lug fitting).I seem to remember there is a conversion plate included, for other types.

**Q: Hi does this fit a vw california t6**
A: If the water cap is the standard one then it should fit.

**Q: Is this item a push fit?**
A: This cap pushes and turns to lock just like the original tank cap. You can change the inserts to suit your water tank. Some tanks have an overflow fitted and some don't. The cap can be changed so that the water leaks out when the tank is full. Hope this helps.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Takes the drudge out of filling large water tank in our Hymer motor home 👍🏼
*by D***G on 1 September 2020*

Gosh! this really takes the drudge out of filling the fresh water tank of our Hymer motor home (which has a large capacity tank)Good quality, well priced, speedy shipping, well packaged.Very easy to use, perfect fit, and negates the need to stand with hose in hand waiting for the tank to fill up (seems to take an age!)Definitely worth purchasing 👍🏼

### ⭐⭐⭐⭐⭐ Makes filling up the tank very easy
*by P***E on 25 June 2021*

This clever little device make filling up the water tank on my motorhome very easy. It saves standing there holding a hose for ten minutes or more and getting sprayed with water. It comes with several adaptor rings to fit various filler holes but just fitted straight into mine. You simply insert the device and click on your hose using a standard tap adaptor fitting. Turn on the tap and allow the tank to fill while you do something else. The only thing that would improve it would be some kind of auto shut off device once the tank is full . On my tank there is an overflow outlet and as soon as this starts to run you can simply turn off the tap and disconnect the hose and the device. A great little product

### ⭐⭐⭐⭐⭐ Great little gizmo!
*by J***F on 31 December 2019*
