1990 Sunliner

[Sunline3698]

Hi, retired pulling 14ft Sunliner. It has a leak below shower. Any information on fixing it appreciated. Other than that, it's a gem. Been across USA and Ontario with it already.

Hi Sunline3698,

Welcome to Sunline Owners Club and congrats to you on your Sunny.

To your leak, and the repair, we need some more info to be able to help better. Is the drain leaking and you need help to repair the plumbing, or is the floor rotted and you need help on replacing the floor?

Please tell us more on the leak so we can help give better info on how to fix it.

Pictures in these cases go a long way in helping show us what you are up against. Please post if you can.

Also what year and model camper do you have? This will help us sort out which camper you have and the way it was made. Sunline changed the shower over the years and the methods of making them changed along with them.

Hope this helps

John

It is a 1990 Sunliner t1551. 14ft. The leak is coming from under the outside bottom below the shower pan. I was wondering also if it is possible to pull up the shower pan to access the tank. I will try to get some precise pictures tomorrow and will see if it also leaks when flushing the toilet, I don't think it does but we don't actually use the toilet. We do use the shower. (We chose not to use the toilet as we are both smell sensitive, we use public restrooms).

OK thanks. The pics will help but here goes from what you told us.

There should be a small access panel to the shower drain trap somewhere. Since I can't see what you have yet, I'll let you know what I have found. Some times the access panel is on the side of the shower the basin drain is on. Other times when the floor plan does not allow a side access panel, under the camper they have a removable section in the black waterproof membrane right under the shower trap.

Hoping you find that access panel, then look for a large nut on the bottom of the shower drain which compresses a rubber gasket. The nut may be loose. See this pic of ours. I'm assuming yours has a nut as well to clamp the drain basket into the shower basin


As to pulling up the basin to look, there are several types of showers they used over the years and I am not familiar with which one you have. The pics will help on that. Some are easier to come out then others. The newer ones are not easy at all to get out. Hoping your older one might be.

The shower water drains into the gray water tank only along with the bath and kitchen sink. The shower is not connected to the toilet tank (the black tank). The toilet has it's own dedicated black tank.

Hope this helps

PS. I looked in the 1990 brochure and did not see a T-1551 model. I found a T-1550 and a T-1661. It could be the brochure did not include the T-1551 for some odd reason or did you have a typo in the model number?

There never was a T-1551.

I have found the exact issue. Where the shower trap goes into the tank is cracked - when draining the shower water is going on top of the tank apparently and into the bottom metal underpinning of the camper then leaking out. Will that WrapIt silicone tape fix this issue more or less permanently or must I take it in for a new trap - I can't figure out how to get the old one out new one in if I do it. The space is pretty small. I tried taking a picture but it was pretty dark - the crack is obvious. Will silicone wrap tape work for this?

If the elbow going into the tank is the issue, the elbow can be sealed back up.

I am assuming the piping is black plastic? If so this is ABS plastic that can be repaired (welded) in place to make a permanent correction.

See these posts on how to fix cracked ABS tanks and piping.

The silicone may be a problem. If it does not hold, then odds are high the silicone is stuck on the pipe and it makes anything else very hard to stick to correct afterwords. Silcone has not shown to hold up well in these flexing situations of the camper when folks tried to use them on roof or joint seams.

Ideally you can solvent weld the crack closed.

Hope this works
