My 455 is built in 2015, now it had leaking faucet problem. Contacted local dealer to replace it but was told this type of Faucet is not available anymore. can anyone share where can I get same unit? I did check Boatnoon, but no stock there as well.  |

You dont need to replace the whole thing, only the cartridge if it leaks. There are plenty of sizes on Amazon, measure yours first before ordering. |

One of ours is leaking as well. How do you get the mixer handle apart? Like the one in the above image it does not seem to have an obvious screw like some of the mixers have. I thought the handle unscrewed but haven't tried that yet. ------------- Wayne W Cruising, currently in the Pacific until the end of 2026. |

| Yes unscrew the handle, then there is a hidden screw inside, unscrew it too, then remove the cover, get access to the cartridge. There is a topic about it covered somewhere on this forum how to take take ot apart, with pics. I will try to find the link... |

Marsella, Thanks for finding the info. I could see the "decorative button" hiding a retaining screw on the other tapes onboard but the one in our cabin is per the Sanya455 image. As you say unscrewing the handle should uncover the retaining screw. Thanks again. I still learn something everyday. ------------- Wayne W Cruising, currently in the Pacific until the end of 2026. |

| I have exactly the model that Sanya posted, and was able to take it apart easily multiple times. At the end I complained to my dealer that it shouldnt leak because the boat is factory new and they dropped me two brand new faucet assemblies by UPS. Boaton price was around 200 Euros something for the whole thing at the time I looked at this problem but I have seen cartriges only on Amazon for around 10$. |

It’s worth mentioning that this leaking has been directly related to over-pressure in the hot water system. This is caused by running the engine for an amount of time which raises the hot water temperature to near 100 C. Eventually the pressure will be relieved by the safety valve but not before the faucets start leaking. Eventually this damages the cartridge and the faucet will leak even under normal pressure. Best solution is an expansion tank which Hanse should have fitted in the first place. There may be other causes but this is the most likely. ------------- Leon / ARCADIA 2018 Hanse 588 Sag Harbor, NY |

| I havent fitted the expansion tank yet and Hanse sure knows about this problem. My Hanse rep advised a very simple workaround which I usually follow - whenever underway with engine running, turn off the water pump and keep the sink faucet open. |

whenever underway with engine running, turn off the water pump and keep the sink faucet open. Actually I followed the same, one faucet kept open with hot water position, another faucet kept open with cold water position. Seems end of day, pressure still damaged faucet. Will for sure add expansion tank after faucet is fixed. Thanks again for everyone's input here.

This is very welcome info! I'd like to order a couple of spare ceramic valves but I am not anywhere near the boat to measure. Can someone post a link to a suitable valve (I'm in Europe). Thanks! ------------- 2016 Hanse 505 #120 |

it is popular ceramic 35 mm cartridge with fixing/retaining nut. When I opened mine it looks like that (google "Reich 209 keramik ersatzkartusche") |

Followed the idea in this post, now need help on last step, how can I take fault cartridge out? Any help here?  |

You have to unscrew the ring that keeps the cartridge in place. Its a bit tricky, you need a special faucet wrench for this, check amazon for something like that |

Doing the same repair now. Don’t know if you’ve had success or not but here’s a tip. That tapered silver outer ring will unscrew to reveal the retaining ring. I used WD-40 to free it. You can’t really get pliers on it and it will scratch easily even if you use a cloth. ------------- Mike S/V Dulces Sueños 458 #087 Tampa, FL |

| This thread is really interesting as i have just brought a 2015 hanse 455 and have the same problem and was suprised no expansion tank and then don't get me started on the madness of the who pumbling system used - i am now thinking of changing everthing to standard Push Fit (JG / Whale) and replacing the system as without very specialist tools you cannot add to the system / repair leaking pipes / change taps. Anyone done that and any advice - i cannot see any connections to the the tanks / pumps that are not non-standard (all look like BSP). I have a 2005 Bavaria before and it was all Whale 15mm and BSP for the taps and had an expansion tank |

Just passed expansion tank exercise on my 458 which should be the same as 455. Check my post here: https://www.myhanse.com/yanmar-4jh57-water-heater-calorifier-shutoff_topic15449_page3.html" rel="nofollow - https://www.myhanse.com/yanmar-4jh57-water-heater-calorifier-shutoff_topic15449_page3.html Can confirm the hot water pressure goes well above 100PSI, which is not good |

For the whole unit, Manufacturer, Reich Part number, 574-971000R We just bought one in the UK which was special order through a motorhome (camping car) Reich dealer. Price ~£180 (210€, $240) and took ~2-weeks. https://www.leisureshopdirect.com/water/caravan-taps/reich-taps/reich-trend-e-with-extractable-outlet" rel="nofollow - https://www.leisureshopdirect.com/water/caravan-taps/reich-taps/reich-trend-e-with-extractable-outlet We had leak plus the chrome finish had deteriorated badly in our forward head. ------------- Ian & Andrea SV Gabrielle (H445) Liveaboards - currently Montenegro. www.facebook.com/sailinggabrielle |

| Thanks Ian - that's great - however from memory the connection to the water system is that printeo push fit system (addly the showers do seem to have 1/2" BSP so easy to change) so it's very hard to swap out - hence why i am thinking of replacing the whole water systems with JG/Whale 15mm |

Hi Duncan, Must admit to not having looked at the how this tap is plumbed in but hoping if there is a Prineto fitting, I can cut red/blue hoses near the fitting then slide over the new tap hose barbs ... but I'll not be back at the boat for another five weeks so we'll find out then. I can see why you'd want to change this pipe system out. Be interested to hear how you get on. Cheers.  ------------- Ian & Andrea SV Gabrielle (H445) Liveaboards - currently Montenegro. www.facebook.com/sailinggabrielle |
