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. ------------- God's pod '11 model 177 '17 Ford F-150 4WD 3.5 Ecoboost Jim and Diane by beautiful Torch Lake "...and you will know the Truth and the Truth will set you free." |

In our pod the pump is a Shurflo 2088-422-144, which is a 45 psi pump, available on Amazon, but if you have yours out you don't need that info. I'd be very tempted to go with a 55 psi model if I had to replace mine.
It sounds the vanes may have no hold on the shaft. Motor working but vanes not turning. Total guess. Probably winter related. I don't like your air only method of getting water out of the lines for winter. Sorry... That may not be it, but it doesn't take much water in the pump to cause damage if it freezes. I hope it's something else easy but a new pump is "only" about $75 - $85. TT ------------- 2010 176 FJ Cruiser |

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. ------------- Mike Carter 2015 178 " I had the right to remain silent, I just didn't have the ability." |

I'll be interested to hear the answer to this. I don't like my idea very much, but as for losing its prime, the pumps are made to run dry, which mine has done. If they can run dry it seems like they must be self-priming, almost by definition. Here's another dumb idea: is there water in the tank? While you have the pump out it shouldn't be much trouble to jerry-rig a hose on the intake side into a bucket and 12 volts to the pump so that you can see what it does up close.

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:) ------------- Mike Carter 2015 178 " I had the right to remain silent, I just didn't have the ability." |

Make sure the screen "jar" isn't cracked.. A common issue with air winterization is that it doesn't get emptied..

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. ------------- God's pod '11 model 177 '17 Ford F-150 4WD 3.5 Ecoboost Jim and Diane by beautiful Torch Lake "...and you will know the Truth and the Truth will set you free." |

If needed, a new front housing can be bought on Amazon...

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.

Jato, Makes sense, the hoses are very good, pretty durable, but stuff happens. On the 177 is the line under the bed and then to the pump at bottom of sink cabinet? I think you have isolated out the pump. I also have never had an issue with air purging, except last time it took 10 mins to get water out of faucet. The only thing I could figure was the line had enough air in it to slow the pump prime. Just strange. I would like to know what you find. ------------- Mike Carter 2015 178 " I had the right to remain silent, I just didn't have the ability." |

Maybe you need to pressurize the holding tank.. ------------- |

Sounds like you've narrowed it down. Glad it's not the pump. Maybe a crack or a loose fitting.

Not sure how to pressurize the holding tank, with the vent by the filling hole, might be a bit of a challenge. BUT anyway it was decided to fill the tank to full by adding the other 20 gallons. Hooked up the water pump and ran it for probably another 20 seconds while it continued to sputter air and spurt water. Then all of a sudden a steady stream of water came out of the cold side which I was running at the kitchen sink, switched it over to the hot side to purge out all the air, then to the shower sink and finally to the water closet. Now I am really confused . It didn't work with 10 gallons in the tank but did with 30 so now I drain out most of the water till I have 3 - 4 gallons left. Repeated the same scenario as above, pump works flawlessly! Hmmm. An air bubble or what, I don't know but at least it now works. Don't you hate it when you "fix" something, but don't know how or what you did to arrive at that result? The hardest part was putting the water pump back in its original position, I managed to ruin a great watch, pulled the stem out and couldn't find it, and also had my patience tested, took the better part of 30 minutes to secure the pump back down in place. One positive, it sure runs a lot quieter than it used to, again, don't know why but it does. After a couple of hours, conjutating on all this, decided to run it again for another 10 minutes until the tank was dry and then added some additional water to make sure this wasn't a fluke; it wasn't. Still runs ! So I conclude by thanking you all for the wisdom shared. That is what makes this a great forum!------------- God's pod '11 model 177 '17 Ford F-150 4WD 3.5 Ecoboost Jim and Diane by beautiful Torch Lake "...and you will know the Truth and the Truth will set you free." |

Hmmmm. Interesting. Probably some sort of air lock, which I'd think a self-priming pump should be able to deal with. Yeah, might have been worth a busted watch if you found the problem and understood how you fixed through your efforts and ingenuity. Really frustrating when you go through all that and don't come out any better or wiser than when you started. It does work now though! TT ------------- 2010 176 FJ Cruiser |

Jato, Good. All sounds familiar to me, still have no idea why. ------------- Mike Carter 2015 178 " I had the right to remain silent, I just didn't have the ability." |

I concur with TT; I think you had some air in the line, and you just hadn't purged it all yet. Glad you got it "fixed"... ------------- bp 2017 R-Pod 179 Hood River 2015 Ford F150 SuperCrew 4WD 3.5L Ecoboost |

I think that having more water in the tank (e.g. full) makes it easier for the pump to pick up prime since it does not have to lift the water as much. I'll get a chance to verify this when we pick up our 'Pod next month.

SH,
I never had this issue until I winterized with air. I had the same issue as Jato, the self priming pump is not a "rapid" self priming pump. The only thing I did to assist was siphon some water thru the antifreeze add line with the pump, that seemed to speed it up. I never had a full FW tank. It just took time for pump to get water. Debatable, but air winterization leaves no water in lines and antifreeze winterization has liquid. Last year when I did antifreeze never had issue. Agree best to try on your own when you get Pod back. Interesting. ------------- Mike Carter 2015 178 " I had the right to remain silent, I just didn't have the ability." |

Interesting in that except for the first year I owned this pod I have always used air to winterize my 177. Since 2012 that has been the standard and this is the first time this ever happened. So while I am glad everything works well I am discouraged in that during this process I didn't gain the understanding of what exactly I did or didn't do that caused the problem and/or the cure. Life and experiences go on. . .
