Leak at the Water Tank '93 T-1700

Ok, so I have a leak at the outlet of my water tank that connects to the water pump. I can see it from a distance, and can't quite tell if the tank itself is leaking, or if I just need to tighten the pipe clamp. Nonetheless, it seems like it's going to be more work to get to the location of the leak, than it is to actually fix it.

Anyone ever need to get down to their water tank on a 1993 T-1700 or similar?

We just sold our 1994 T-1700 and I don't remember just where that outlet is located. Can you get at it from the inspection plate on the tub? Maybe go in through the cupboard under the stove/sink and take out the shelf. At least there you wouldn't see any modification if it didn't go back together the same way. Good luck. The water tank is pretty inaccessible in the 17. Maybe someone out there has done this and has some other suggestions?

JohnB is on a distinguished road
I have been to the water tank pump fittings but not on a T-1700.

Do not know if yours is made the same as mine. On mine there was is take coupling molded to the side of the tank with NPT threads in it. The plastic coupling is not very rigid as it is plastic and using tapered NPT threads can spread the tank coupling fairly easy.

I used a good qty of Teflon tape on the fittings before tightening it it. Have not had any issues so far and that was now about 5 yeas ago.

Do you know if the leak is from the fitting into the tank or the hose onto the fitting? They are 2 different problems.

Good luck and hope this helps

John

An update on the dilemma...

To access the fitting that was leaking, I had to remove the fridge and wooden panel beneath it. I also removed some elements of the interior cabinetry beneath the stove-top and sink to try and figure out the best viable option of fixing the problem. I learned a few things...

Lesson 1 - Replacing the water tank seems to be almost impossible. Anyone with a T-1700 that has to replace a water, I feel for you as just short of ripping out all of your cabinetry, I'm not sure how you would go about this...

Lesson 2 - The fittings that used on these water tanks are cheap and pathetic.

As the poster wrote above, it is a cheap plastic NPT fitting that is fitted against the tank; well, mine was split, as well as what looked like some kind of flange (green color). There were only two options to fix since the tank is near impossible to replace...

1. Cut a hole in the top of the tank to get behind the fitting. Remove it/Replace or somehow seal it up. Cut a new hole for a new fitting, and then patch the access hole that we would have cut from the top. We did not chose this route.

2. Use a combination of Teflon, pipe dope, DUMDUM tape caulk, an additional steel hose clamp and PET plastic welding to seal the crack.

Option 2 was a success. If I can get a picture, I will.

I have a T1700 also and you are right it would be quite a task to get the tank out. My favorite fix is JB Weld I have used it on some amazing things with great success. My tank system also had a leak but it was not the tank it was added fittings for the pump and shut off valve. It had a very small leak at one of the joints and they "fixed" it with a shimmies wrapped around the fitting worked as long as you remembered to wring out the shimmies. The pump is not a real easy thing to get to either.

Not the best work I've ever done, but it sure beats trying to replace the tank!
