Water Supply Connection - Leak
So I was given a basically new toilet by a family member that bought a new RV and they upgraded their stock toilet. They had the shop doing the update box up the new unused one for me. So I installed it right before winterization last year along with other work I was doing to my fifth wheel... Now I have an issue. I hooked up the water supply and it high pressure leaks. Arn't the threads on the water supplies for RV toilets all the same? I didn't use thread tape but there wasn't any orginially on the orginial toilet... Should I use some? I havn't checked but a buddy said maybe there is a gasket on the female side coming from the rv...? I was thinking about replacing the supply line with a new steel braided line with an cut off valve built into it anyways...
Basically what do yall think my problem is? Is there any special ways these supply lines should be hooked up.
