This gadget is somewhat mandatory for RV owners - you need to flush out your hot water tank once a year and this gadget is perfect for that. It has a shutoff, which you need, and the long thin hose, curved at the end, and sized to reach all corners of your heating chamber.
Only problem is, the quality is questionable. Mine arrived in new sealed packaging with a split in the wand where it connects to the yellow body. This makes it useless, but it can easily be repaired. I''ve seen one reviewer who described the exact same issue - and they worked around it with a piece of gaffer tape. Another reviewer talked about how the wand popped off under water pressure, and was ejected into the tank, never to be retrieved again.
So let me see... not only does it not work, it is also dangerous if you insist on making it work. Baad.
As always Amazon is awesome, so when I initiated a return, I had a choice to either get a replacement sent out immediately, or get a no-return refund. I chose the latter. My rationale is that there is some chance that the replacement has the same issue (other users have had this problem too) or develops the same issue after using it, and I didn''t really want it anyway, for precisely that reason.
Now I see what this gadget is all about, it occurred to me that I could make my own, and way better. Use a brass hose shutoff, and then get a 3/4" to 1/4" hose barb adapter, and then fit some 1/4" tubing on it. If you use copper tubing, you can easily bend it to the right shape, and form a nozzle at the end of it. Yes it would cost more than $10 to make it, but probably not much more than that anyway.
I could also try to repair this Camco one, since I was already refunded, why not give it a try? My approach would be to first try to glue the crack, to keep full length, and if that doesn''t work, just cut it off and shorten the tubing by 1/2". I tried repairing the split with super glue (cyanoacrylate) over night, but it didn''t hold at all. I could also try PVC cement, but neither would be holding it structurally - they usually require totally flat surfaces to bond properly. So I cut it off. Done. The tubing is not flexible at all, and would not go on easily. I tried to dunk it in boiling water, but that didn''t soften it. It''s not like 1/4" vinyl tubing, it''s more like hard PVC plastic. So I pointed the heat gun at it, watched it start to melt, then pushed the tubing on the fitting. Done.
Now, to ensure it won''t split again -- and more importantly, not shoot off into the hot water tank while flushing it -- I need to upgrade it to add some type of protection with clamping force. I thought about putting a hose-clamp on it, but those things are dangerous, with sharp bits sticking out, and a clamp would also shorten the usable length of the wand even further. So I decided to put some heat-shrink tubing. The heat-shrink is pretty stiff and strong once shrunk, would provide a bit of clamping force, would completely envelop the end, and protect it from external damage. A blow from a sharp object at the fitting would be enough to initiate a tear in the plastic which is under tension.
As for Camco -- if you''re listening -- you can *improve* this product and make your customers happy. I think you should put a clamping ring over the fitting, such as a pex-style copper or plastic clamping ring. The copper ring uses a compression tool to provide clamping force. A plastic ring is used in some types of pex fitting, where you use heat to expand the plastic fitting and it shrinks in place as it cools. It''s also possible to use stiffer packaging but that won''t cure the weakness, only make it less likely to happen in-transit to the consumer.
So, there you have it. Get to it, Camco!
