Hello everyone. This is my first post. I have a 1968 Rolls Royal trailer. Love it. Everything is in good working order except for the running water. I located the pump system and filled the tank and turned it on. The pump made noises but no water came out. I looked at the pump system and I see the pump but can't figure out what the other two devices are in the pictures. I've attached the pics here. Can anyone help me figure out what I am looking at here? I recognize the pump, but what is the thing with "FURNAS" written on it. Any help to help me solve this would be appreciated.
Here are links to the pics:
Thanks!

I can't tell from your photos but it might be a compression system? which uses air pressure to provide water. The Furnas box looks like a water pressure switch, which I've never seen in a trailer. They are used in home well systems to turn the water pump on and off. Is there a big roundish metal tank?
Can you take photos with a wider view?

Vikx, thank you for the reply. sorry, It is in a tight space. I will try to look for the pics I have at a better angle. The trailer is a1.5 hours away right now, otherwise I would take more shots. I added notes to one of the shots. I think there is a compression tank there at the bottom of the shot in ths pic: thoughtfoundry.com/staging/20200515%3D1968_rolls_royal_pics/IMG_4559%3Dwith_notes.jpgI found another angle of the pump setup, hopefully this will give more info:
Thanks! |

The grey Furnas box is definitely a pressure switch. It turns the pump on when the pressure gets lower, similar to a home well/pump system. (look up how it works) The thing behind it (black with a grey top) is an accumulator tank that prevents pump and water system noise. It's really not necessary but people like them.
The pump is a water pump rather than a compression system air pump. It may need to be primed or replaced. Sometimes they just loose the ability to pump due to bad parts. Or the pressure switch may be bad. I'm not seeing the necessity of the switch, you might be able to bypass it but you said the pump tries to work, in that case, the switch is probably working.
It appears somebody knew what they were doing when they plumbed this part of the water system. Next time you get to the trailer, see if you can find a tank about 3 feet long, either round or flat and take a picture of it. This could have been changed out from a compression system by a home pump expert. LOL. You say you filled the tank, does it have a shut off valve somewhere? If there's no water to the pump, no water out...

Vikx, Thank you so much for your help. I wanted to order a pump but didn't know if I needed to replace anything else. Do you have any brand recommendations for pumps?

Pumps depend on what you want it to do. I use tiny "one fixture" pumps for my trailers. Yours will need a Shurflo 288 or 8000 series if it's got a water heater, toilet, etc.
Find out what is wrong with your system before buying a pump. Not sure I would keep the pressure switch. Normally, the line from the tank is connected directly to the pump and out to the rest of the trailer. (there's often an inline filter before the pump)
I'm not sure how the pressure switch will operate because with a modern tank there is no pressure... This needs to be researched a bit more. The only thing I can think of is to ask a well/pump specialist to see how the pressure switch might work in a trailer.
