Water Pump

Finally got our 177 out of hibernation today and much to my chagrin, water comes out in spurts.  Double checked the bypass valves and also the one used when I blow it out with compressed air, check.  Took water pump out and physically looked to see if anything was amiss, found nothing.  Screen on inlet side of pump was clean as a whistle.  When running I can put my thumb over the outlet and hold the little bit of pressure that is generated.  I couldn't find any hairline cracks in the 3 baffles where the pressure is generated inside the pump proper; or is there something else it could be? 

The one thing I thought odd when I turned it on was how quiet it was.  For the past 6 years I always found it kind of noisy, maybe that was an indicator of something amiss.  If I indeed need to replace pump, what would you recommend - hopefully one that is a tad quieter than the one that FR installs.  Thanks and enjoy this Memorial Day weekend, honoring our nation's veterans.

Jato,

How long did you let it run? When I use air to winterize, it really surprised me how long it took pump to prime. You might try taking a jug of water and putting the antifreeze hose in it, I had some luck with that. Might also be why it's so quiet, not primed.

Probably more accurate to say it doesn't prime fast. I had same problem after air winterization, why I suggested put the antifreeze line in a jug of water. I can only hope Jato has water in tank:)

Thanks TT I will try that tomorrow afternoon.  I may be old but yes Mike, I do have 10 gallons in the tank.  Mr. Furpod, after blowing out I still unscrew the screen jar even though since doing this every year since 2012 I have never had even a trace of water left in it.  The motor works fine so it has to be something with the vanes although nothing noticeable could be seen with the naked eye and a bright light.  Thank you everyone who gave me some pointers to check out.  Will let you know after I do the TT test tomorrow afternoon as far as how that pans out.  Had a birthday celebration for one of my boys tonight, this can wait.

Well here is the deal.  Opened the 3 way valve under the sink and ran the pump, works perfect.  Also took the line off in front of the screen jar, pump works perfect.  So . . . . all I can figure out at this point is I must have a hole in the plastic line somewhere between the fw tank that has 10 gallons of water in it and the water pump.  Do you concur?  Hooked up the pump to the water line, as it was in the beginning and get a little water, and a lot of air.  At this point I am thinking a hole or crack in the plastic line.  Will search for that tomorrow after I get off work, hopefully that will be by noon or so.  Will keep you posted.
