Domestic Water Pump

I have a 2007 CD 25. My water pump seems to be making noise when turned on - but is not pumping water. Have any of you had pump failures this soon after purchase? Any suggestions for trouble shooting or am I going to have to replace the pump?
 
Hi Dave,

Yes, I've heard of it. I also have a 2007 CD-25. We are on our third fresh water pump. The first one failed at a bit over a year. The second one (same model) didn't make it that long, and that was after I moved it up in the bilge so it wouldn't sit in the water. The third one is a pump designed for marine use... when I looked up the pump #, I found that the original and replacement pumps didn't have that designation.

Our first pump failure started with the symptoms you describe, and then worked intermittently for a couple months. I'd recommend you move the pump off the bilge bottom and replace it with one designed for marine use.

Best wishes,
Jim B.
 
The pressure switch on my Shurflo "went" about one week into ownership (new 25'). This doesn't sound like your problem but in my experience, assuming your pump is also a Shurflo, these people have been pretty good about responding to questions. I'd call or e-mail a description of the symptoms just to see whether they have suggestions. Good luck.
 
You might check to make sure your pump outlet hose goes up continually on its way to the outlet port. If you have a low spot it can trap air and cause a vacuum seal. I had this issue on my boat and didn't realize it, ended up burning up my pump (it was only 3 years old, a Rule 1000 GPH). I replaced it with a commercial grade pump made by Johnson pump in Illinois. It is rated for submersible operation (1600 GPH) at around $65.00, I thought it a better choice than the stuff that most marinas carry for about half the price, (just seemed to be much more substantial).
 
Hi Dave,

After two failures in the first year, I replaced the failed water pressure pump on my 2007 CD25 with the Jabsco "marine" Model #31395-0092. I mounted it on top of the battery shelf, which seems like a much better location than the always wet bilge floor area. After about a year and a very cold winter in the water everthing seems to be working well.

Thanks, Dick
 
Be sure that there is a fine mesh filter before the pump (between the water tank and pump) some boats have this filter, some don't. Any debris can be caught in the valves. The pumps are fairly easy to rebuild--and I have had some which had some debris and only needed cleaning. When you pull the head pay attention to all of the springs and check valves--and most likely you can fix it--maybe even without a rebuild kit.

The old Jabsco diaphragm pumps were so un-reliable, that when we were full time cruising we had quick change fittings on both the plumbing and electical. We had to rebuild a pump every six months. They usually went out when Marie was in the shower! I always kept a rebuilt pump and several rebiuld kits aboard. The newer pumps are far better than those.
