Low point drain trouble

Question

I have a 1997 Fleetwood wilderness travel trailer and my low point drain in the back has obviously been redone by the prior owner. Recently, one of the tubes started pouring water out of it. It's been dripping for a while now but just started pouring water today. There is not a cap on it. I'm wondering if I should cap it out look for a busted water pipe. I have bypassed the hot water heater and the water pump since we are always on city water. I'm scared if I cap it will the water start leaking inside the trailer? And yes that is a bolt in one of the tubes. I didn't put it there but I'm gonna replace it with a valve.

if its a low point drain it will either have a cap or a valve to be able to drain it.&nbsp; if yours has the valve and you closed it and its still pouring out then you need a new valve.&nbsp; if it was a cap system like mine then it needs to be capped, or you can replace the caps with a valve.&nbsp; oh and there is no picture in your post so I have no clue what bolt your talking about&nbsp;

Ok I capped it and now it's leaking out around the tube. I found a crack in the tube so I'm going to replace it but I'm not sure where it leads to it how long it is. If we turn the water on it pours out but we have good water pressure. I thought the low point drain was there too build pressure in the lines and if it wasn't capped there would be no pressure in the lines. I have bypassed the water heater and the fresh water tank as well as the water pump.

that is all you can do, fix the cracked section and see if the leaking stops.&nbsp; did it get frozen over the winter with water in it ?&nbsp; I know I got caught last fall by a freak cold snap but luckily all that was dammaged was my water heater isolation valve.&nbsp;
