Newbie Question

Howdy, Howdy. Have a plumbing question. Just bought a 91 32ft Holiday Rambler Alum-Lite XL, she is almost brand new condition, and we are the 4th owners. Learned we needed a water pressure regulator after being hooked up to house water pressure for about 8 hours while I tried to fix a leak at the water heater. Got that fixed but now there is water running out of a drain pipe under the trailer by the water heater. There are 3 short pipes, grey, about 3 inches long, hanging out of the trailer and water runs out of one, even after putting a regulator (40 lbs) on the inlet. Is this normal, or did a pressure relief valve open. More than a drip, but not a gusher. Former owner said it did that with them too. Been looking through all the literature they kept but have not found anything yet. Maybe the brain pool here can help. Thanks in advance.

Are they maybe drain valves that are not closed? look in the area (the bay or cabinet that is above them for a water drain valve that is still open ot leaking. There should be no water leaking out of any line under the trailer under pressure. look for a leaning valve.

Possible fresh tank overflow? Check your valve position on the fresh fill control. Could be just a little open.

It sounds like your water heater has a bypass system on it.. it's 3 valves that allow you to bypass water heater for antifreeze the system and drain the water heater.. for winter storage.. it is meant to keep you from having to use 10 more gallons of antifreeze you don't need.. so.. 1st check the pipes hanging down.. follow them inside the bay.. most of the time.. there is a secret door panel.. you pull it out and you should be able to see the valves.. try them see if you can get to stop.. but really 30+ yrs old water heater.. it could have ruptured.. so that's a real possibility.. sometimes they hind the valves on the back .. so cell phone with camera and flash and record up under and over water heater is best friend if your head does not fit.. use is all over.. also recheck drain plug on water heater.. they are usually plastic and pop out a thread or 2 to stop over pressure.. then crawl under coach.. mine has a hinged door.. that gives you access to water heater.. good luck with that.. mine is so rusted that Thor and his hammer could not budge.. keep us posted

Newbie question

Thanks to everyone for the answers. I also talked to a rv service person who said it might be the check valve in the water pump. Can someone now tell me where they hid the water pump in my trailer. I looked everywhere I could think of, no luck. Once again thanks in advance. You guys are golden.
