I wonder if there is a tape you can carry for emergency repair?

When the pinhole appeared in my hose I made a temp repair using a liquid type tape, let it dry and then applied another coat.  I then wrapped that with a bit of fusion tape.  It lasted a couple days before I could acquire a new hose.

I don't want to sound dumb, but what is fusion tape?

Fusion tape is generally a self bonding, self fusing silicone/silicone rubber tape.  It is non sticky to the touch and needs no tools/heat to make it work.

Update on the fix:
As Barry suggested previously, I called Thetford Customer Service today re the leaking hose.  All I needed to tell them besides describing the leak was to give them the serial number on the Twist-On unit that we have and the date we purchased the PC.  Since we are still within the one-year warranty period, they agreed to send us a new hose.
I call that great customer service!

Thanks to those on this forum and this thread I have been alerted to a real problem---the sheet metal screws that could pierce the hose. 

I checked our 2350 today and sure enough, one of those little screw ends was almost against the hose and would be with only a little  vibration or movement of the hose.   SO, I twisted the hose from its existing position where it connects to the pump, adjusting it about 15 degrees to move it away from the screw.  Then, I cut two pieces each about 1/2 inch long of insulation from a #12 wire and forced the little piece of plastic insulation (which is now is just a small piece of tubing) over each screw end.  They fit very tight and I suspect will be there from now on.   I was packing for a trip and didn't want to take the time to replace the screws with small stove bolts.

I sent Thetford a email asking about a temporary emergency repair.  It is scary being out and have to dump and stuff squirting all over the place.  This is their reply:

"Well when the hose breaks or has holes in it we, as you said, suggest replacing the hose itself. But if you were looking for a temporary fix you can use any type of tape or glue that would stick to the hose. Personally, I would suggest using super glue or hot glue to seal it, if you were looking for tape I'd suggest duct tape or masking tape".

I have been confused as to the pin hole so many of you deal with.  Is it where the hose comes out from the hose storage compartment?  Or is it located somewhere else?

If located by the pump, could you file down or replace the screw as some have mentioned, cut off the bad part of the hose (the last 2" or whatever) and re-clamp it?

Does anyone have a picture of the sharp screw and the damage it has caused?  I will have to look at ours and see if we too have this "sharp screw" condition.  We have not yet had a hole in our hose and it has been 7 years now.

Ron,

The hose leaks seem to be happening at various points.  I found the leak in our hose about 5” inside of the storage bin in its relaxed state (about 12" from the end of the hose where it connects to the pump).  It was in the seam of the hose and looked like it had just split apart a little there.  That part of the hose would never make contact with the ground during normal operation even when it was fully extended.  So I’m thinking that it was a manufacturing defect that did not stand up to the pressure inflicted during dumping.  

Others have had punctures in the hose just outside of the storage bin.  The hose in ours goes through a hole in the end of the storage bin.  The hose is encased in a small plastic bushing there that protects it from the edge of the hole in the bin.  The plastic bushing is held in place at the end of the bin by two small screws--sheet metal ones with sharp pointed ends.  Some hoses have been punctured by contact with one or both of the sheet metal type screws.  While I was replacing our leaking hose I replaced the sheet metal screws with short machine screws and nuts that have no sharp points that could puncture the new hose.

I'll try to post two photos of ours:
One shows hose in storage bin going out to the pump.  Ours had a leak about 5" inside of the bin.
The other shows the hose coming out of the bin.  The sharp machine screws use to be on each side of the hose (where you might now see the machine screw heads).

As a precaution, I also replaced the self tapping screws with stainless steel machine screws and nylock nuts after reading all the posts.

For an alternative, an easy fix is to buy small plastic caps called Screw Protectors. I bought a bag of 4 pieces at Lowes for about $1.00. Buy the size that fits 1/4" screws. They fit snugly over the tip of the self tapping screw and eliminates the sharp point. I used one of these on a screw that was protruding upward in the propane compartment. I jabbed myself several times on the screw before the fix - less painful now.

Thanks for the pics and detailed explanation.  I know your situation better now, and will see if I have simply been "Lucky So Far".

A few hose issues aside, has anybody had much of a problem with the Sani-Con pump itself. We've never had a macerator in any of our 4 RV's.
Listening to the hose issues, I think we'll carry an extra hose with us if/when we get a PC.... 2o2

We've had no trouble with the macerator pump during this first year of owning our PC.  We had never owned an RV with one before and really appreciate having it now.

A nice feature with the way it is connected to the PC is that you can simply bypass the macerator if it were to fail to operate.  Just connect up a standard style sewer hose to what is known as the "emergency" dump valve at the rear of the coach and dump in the old fashioned gravity flow method. 

In fact, we carry a 15' hose to connect to dump gray water regularly when we're in an RV spot for more than a couple of days.  Since we only use it for gray water it never gets stinky in the storage bin.  Here is the one that we use:

When it's time to dump the black tank we just whip out the little macerator hose in place of the big one.  Love it!

I already have that hose sitting out in the RV barn leftover from our previous class C. Used it once for grey water. That setup for dumping both ways is a super! idea.....
