More Guppy Repairs

On our last excursion we discovered that we had a water problem. When using the pump for water from the holding tank there would be a burst of water and then a trickle. Thought maybe the pump was wore out. Pulled the plywood off the bed to get at the pump. Saw that it was almost 29 years old, it was made in '97. Started looking online to get an idea how much new pumps cost and last week stopped in a RV dealer to price pumps. Decided before buying a new pump would check the screen between the tank and pump.

In line screen after I took it apart and cleaned it.



After pulling the screen and cleaning it, I looked at the tank and saw it had a couple of bathtub rings inside. So I pulled it out and started cleaning it. 

It's cleaner on the outside than inside.

Looks like it has a date on it, 10-18-88.
This is the original tank that has been in the RV since it was built in '89. So far I've filled it with soapy water and agitated it by using a blowgun with a piece of small tubing on it. I would stick it in thru the filler hole and move it around while blowing air. The tubing was soft enough that I was able to bend it and direct the air at most of the dark lines. 

Today when I drained the tank after I had it soaking for a couple days, I discovered that the water wasn't coming out of the line very fast, just a trickle. Took the line off the fitting on the tank and blew air in thru the fitting. The water came out at a good rate after that. Looks like the screen was plugged and the fitting on the tank may have had something restricting the flow.

The setup I used to test the pump.
Decided to test the pump, so I filled a bucket and ran the pump. At first I wondered why it kept running and the level in the bucket kept going down. Then I remembered I had drained the water heater. It took most of two buckets to fill the water heater. After that the pump shut down and I did my test, I opened a faucet to see what kind of water pressure there was and it gave a good stream after the pump kicked in. I don't think I need to replace the pump. It still won't give you a good shower (The Old Lady says it's like taking a shower in a phone booth even when hooked up to city water), but at least you won't have to wait a long time to fill the coffee pot!!

Right now I have the tank filled with water and some bleach to sanitize it. I'll let it sit for a couple days before draining and rinsing it out. I'm going to replace a couple hoses when I reinstall the tank. The hose for the drain is pretty black inside and so is the vent line. I'm also going to put in a new valve for the drain.

  1. I replaced a water pump in Alaska. I think it cost me $80 back in 2006. I haven't even started checking out the Class C I purchased back this winter. One thing and another has kept me busy. Have to hook it up and go through it this weekend. Would like to take it out for a trial run trip.
