Ptitchuisse Posted February 3 Hello boaters anyone here moved the water pump located behind the galley fridge to the engine compartment ? wouldlike to move it the and add a filtering system thank you! Share this post Link to post Share on other sites
cyclops2 Posted February 3 Why ? What reasons ? Curious. Would that cause heated water ? Share this post Link to post Share on other sites

Ptitchuisse Posted February 3 The main reason is to be able to filter the water (coming from the tank/water pump) and from the city water line. I am looking at adding this filter (http://www.safh2ouv.com/Boat---RV-Owners.html) - I have limited room behind the fridge so would like to move it to the engine compartment. As we boat/anchor on Georgian bay, it will give us more water autonomy, without having to stop to a marina to fill up the tank. Please it will filter the water when hooked at the marina The second, less important concern, is the vibration noise against the hull. The fridge might be pushing the pump against it and it is making a crazy noise anytime the pump is starting (ie in the middle of the night when kids go to the bathroom :)) Share this post Link to post Share on other sites

cyclops2 Posted February 3 Noise / banging could be pressure switch acting up or set wrong. A piston pump can bang a lot. Chech mounting bolts . Chech pressure switch ON & OFF settings. Use a none piston pump. Use right softness rubber bushings to secure the pump.. Share this post Link to post Share on other sites

Does it taste bad or hard water? water from the marina smell yes and we are already using a RV filter cartridge directy at the post.

Curt Posted February 3 If you want to relocate it, it’s helpful to determine if your pump will work in the new location first. Suggest that you determine if it’s self priming or, if not, whether the new location is lower than the water source and always wet; whether the motor is rated for service in an engine compartment (flammable/explosive environment); and whether the unit has enough head and flow capacity to push the water wherever it has to go (head is vertical displacement; flow is GPM and pressure). In your documentation the pump manufacturer and model number should be identified. If not, it’s on the pump. Some internet research on the manufacturer’s site will answer these questions. Splicing water lines is easy. Good luck. Share this post Link to post Share on other sites

The fridge might be pushing the pump against it and it is making a crazy noise anytime the pump is starting (ie in the middle of the night when kids go to the bathroom :)) Most of these pumps are noisy by nature, just FYI. What you're hearing could in fact be the normal sound the pump generates and there's actually nothing wrong with it. Keep that in mind. If you do relocate the tank and pump and add that filter, where would you place it? Do they suggest a specific in-line location? I'm guessing most likely post-pump since you'll want the water to be filtered after it passes the tank and pump. You'll also have to check and see if the current pump has the capacity to push through the filter, or get a more powerful pump. Share this post Link to post Share on other sites
Curt Posted February 3 The vibration/noise could be because it’s trapped between the hull and fridge, the water line is loose and slaps when pressurized water is pushed through or cavitation (air in the system). It’s not a piston pump, rather a centrifugal (impeller). If mounted tight, with isolation bushings, they don’t make much noise or vibration. Even when failing they don’t tend to make much (abnormal) noise or vibration. Noise and vibration are subjective though. And, you do know it’s on when it cycles. So...

Hatem Posted February 3 This is mine. Original pump from Chaparral and it makes a #$%$&$% racket. Always has since I bought the boat almost brand new and it's mounted well. Notice the little screen filter container is pre-pump. Share this post Link to post Share on other sites
cyclops2 Posted February 3 I did a web search of the Shurflo pumps. They all have that surging noise. Normal. BUUUTT The cure is your water flow is to SMALL. So the pump is surging. The best cur is to install a ACCUMULATOR tank pressurized to 30 PSI...…… That cured the surging banging. People said it ran quiet when the toilet was flushed !!!! High volume no surging noise. Simple. If interested I can get the site & post it. Share this post Link to post Share on other sites

Original idea was to pump from the lake, then filter. But we were thinking to filter the whole thing (water tank or city line) Share this post Link to post Share on other sites

Hatem Posted February 4 18 hours ago, Ptitchuisse said: I think this is the same brand, but mine is on the wall behind the fridge. Where is your water tank? 2013 Signature 330, right? Is the tank in the engine compartment? If you relocate the pump, you'll have a bit of re-piping to do to extend the lines. Ideally the pump should be next to the tank. And what is the main goal besides reducing the noise, more water capacity via being able to filter water from the lake? Maybe installing a grey water system would be a better alternative for you, if you're goal is not necessarily being able to drink it. A grey water system would help extend your current water capacity if I understand that's the way the system works. Share this post Link to post Share on other sites

Already not really close to the tank I will need to look at the grey water tank. Extending the water capacity would also add weight on the boat Share this post Link to post Share on other sites

Extending the water capacity would also add weight on the boat I'm looking at the layout of a 2013 Sig 330 and the pump is actually located in the best spot possible IMO. If it's behind the fridge, that means it's right under the galley sink, yes? Then all the supply lines are relatively short runs. Galley sink, head (toilet, sink & shower) and even cockpit sink above deck. The only long run is to the transom shower. Personally, I would keep the pump where it is and if you install that filter, try to get it close to the pump if you have the room. Share this post Link to post Share on other sites
Curt Posted February 4 Another way to reduce noise, assuming the other things that have been suggested are ruled out and we’re talking about the common “whirl”, get a length of insulation, sew it into a cylindrical shape and slide it over the pump. A pair of long wire ties to “grip/cinch” it in-place works well. Suggest a U.S. made marine or aerospace grade vinyl with an anti-fungal and flame retardant as the cover that the insulation is sewn into. A less expensive vinyl is one marketed for awning/tent use. Provided U.S. made, these should also have an anti-fungal and a flame retardant. Look for NFPA-701, E-84, etc. These are the common flame standards. A yard or so should do it. For about $20 to $30 you’ve accomplished less noise (again, assuming the other stuff is ruled out or corrected as needed). Share this post Link to post Share on other sites
Hatem Posted February 4 That's a good idea, Curt. In my situation, since I have the room to do it and if the noise was too bothersome to me, I would do the same thing but instead of a cylinder, I would just make a small box out of some lightweight material as a cover and line the inside of it with some type of insulation material like you suggested and place it over the pump and clip it with a couple of screws. That would probably muffle the sound considerably and at the same time, not suffocate the pump and plausibly cause it to overheat. The same foam insulation material Chaparral uses under the hatch would probably work well. Share this post Link to post Share on other sites
