OFFICIAL - 450DA Owner's Thread****

Fresh water question. Both bathroom facets have awesome pressure. The kitchen and bar facet have almost none? Do the two pumps do different parts of the system or just add pressure to the system?
 
My system has been changed by the PO where the pumps were moved off of the engine room bulkhead to the ER bilge area.

Beyond that caveat, on this boat the pumps provide pressure IN TANDEM, pressurizing the entire system. It is my understanding, but not gospel that this is the factory setup.

Suggest you check the strainer in the faucets that are operating at less than par pressures.

By the way, one of my pumps will on occasion trip the breaker - i am suspecting a weak breaker but it,s still aways down the list.

I continue to find sediment in the pump pre screens, which I continue to monitor and clean periodically.

The addition of an accumulator with a pressure gauge has been a big help in adjusting the pump pressures.

Also, I added an in-line filter for the icemaker and a serious household water filter to the galley - no more need to bring on fresh water for coffee/cooking.

Saverio,
while we dont have the same boat, I had a similar issue when I first bought mine.
In my case, the kitchen sink was made by Grohe and there is a cartridge the goes in the top of the faucet and a quick couple on the lines that feed the sink.

I replaced them and solved the issue.
you will need to check models but mine looked like

and

Note the quick coupler comes in different flow rates(color)

Mark,

I discovered that the new owners of B&G don't support the old Network series of instruments. I was able to get my VHF repaired and reset to new specs about 5 years ago, but on a second go-round in 2021, the mother board needed to be replaced and there was no support for parts and I had to replace the VHF with an ICOM that fit the panel.

This is who I used:

The phone number I had for them was 954-229-0208, but I note on the above website th at the number has apparently changed.

I had an additional complete set of B&G network instruments but the new owner of my 450DA wanted them with the boat. He is working in Venice, Italy until the end of the year so I cannot contact him until then. As an option B&G instruments occasionally show up on eBay.

Hi,

We can supply you with a replacement that will fit in this

hull housing and work with the Network system.

Hello all,

Have owned a 1999 450DA for 12 yrs and she's been flawless (up until now). Bilges always dry, solid decks, no evidence of leaks, flawless engines, etc. Last survey (for reference) was done 5 yrs ago for insurance purposes and passed with flying colors. No issues until today.

Just put her on the hard for the winter and was busy cleaning her. Opened the large hatch in the cabin sole in order to clean out the gray water sump when I discovered the floor was cracked pretty severely. In addition, the section where the cracks were was raised (swollen). When I lifted a cracked section of the flooring, I found the underlying wood structure to be quite wet to the touch.

Trying to figure out what thee cause of this is. At first I thought a leaking sump, but the flooring in the whole area is dry to the touch, saw no evidence of standing water, water staining or the foul odor that accompanies a leaking sump. I even went as far as disabling the bilge pump and filling the sump with water, but I found it not to be leaking. Also no evidence of water on the stringers in that compartment (no stains, etc.).

I usually have miscellaneous stuff stored there that covers the floor so I can't really say how long this has been going on. Ironically, all the stuff stored there is also dry, which makes me wonder where the water is coming from. Its obviously coming from outside the compartment, probably the area between the stringers and hull.

Looking for advice from the collective hive to try and figure out what's causing this as I can't find any evidence that water has leaked into that space from above or from the sump. Also concerned as to how that wet floor will affect the integrity of the boat both short and long term.


UPDATE: Went back to the boat with a friend who has a skipper moisture meter. The floor as well as the stringers pegged the meter. The stringers in the compartment just forward also pegged the meter, although the floor there did not. Might be time to drill a few inspection holes in the stringers and see what shows up. Since there are no limber holes in either compartment, I can't check to see what, if anything, is between the stringers and the hull.

Your input is greatly appreciated.

There is no floatation foam in a 450DA. What you see under t he floor in the bilge is expanding closed cell sound deading foam.

However, don't be fooled by the term "closed cell". If you let it stay wet it will soak up water and smell like small dead animals!

Thank you. No odd smells as of yet, but also have no idea how long the flooring has been wet. Working on tracking down the leak. Fridge, washer/dryer water connections are good. Working my way one connection at a time, starting with fresh water system....

I suspect the floor was compromised by water over the years and when they lifted the boat with the slings then set it on blocks it buckled somewhat.
 
heres a photo of what I found under the salon table posts:
