Bronze equipment can be found on http://www.italnordic.se and the things we need is not that expensive. For some reason I believe most of the products are made in Italy.

Today I started replacing the seacocks on my 2006 Hanse 400e. The hose connection from the toilet just crumbled.

Based on the information shared on this thread I am also in the process of replacing all thru Hulls on my 2009 Hanse 370e. Based on the recommendations on this forum I have gone for True design thru hulls. True Design suggest that the Ball valve should be directly fitted to the thru hull fitting however I notice on my boat there is a male to female 90 degree connector fitted directly to thru hull and then the ball valve is fitted to 90 degree connector.
I would welcome other members opinions on this. Will fitting the 90 degree connector directly to thru hull be cause for concern. Regards Alan

Hi, if space allows, I will recommend having the valve straight on the thru hull and a 120 degree bend after it.
This gave me both shorter hoses and less restriction inside the hoses: ![]() Edited by Lykke - 31 January 2022 at 18:58 |

If this fits well in the cabinet it looks great! Had I known about this before I would have done the same with my bronze equipment. Valve directly to the skin fitting - 100% the best!

Looks nice,
But the brand of the bended hose tubes is not the same as the valves I suppose. Which brand did you use ? Gerard

greetings all
If I may add my tuppence to the excellent advice and information here, the inspection of any critical boat component should never be based on periods of YEARS - it is the environment, use and climate that creates variables -inspection periods should be based with due consideration to the afore mentioned things. I also sail every week on my race boat and do physical checks of key components every few months but with our Hanse which is used like a caravan and never raced I prioritize critical items differently-in the interest of relativity to this thread it is the environment that has greatest impact on the failure of the metal fittings. Eg if you are in the northern hemisphere there is every good chance that your boat spends periods time winterised, on the hard, and lesser time in the water or if your waters have higher or lower levels of salt concentration than the urine in the toilet lines reacts differently in the chemical process of the metal breakdown. Our boat is immersed all year round in sea waters. When I replaced mine at around 5 1/2, years the worst was the cabin toilet and crumbled when the plastic hose was being removed but the seldom used front berth toilet was much better - it is seldom used. The only valve that I did not replace with Trudesign was that on the sail drive - it was inspected and was sound but had it replaced with a bronze fitting. Reference to Trudesign website provided technical information that allayed all my concerns in use of a non metal based valve system plus one of my earlier yachts I owned some 39 years back still has the then a little used but radical radical “non metal” fittings installed - I think they were Marlon brand but only a guess.

I want to ask you all for some advice. I own a 2007 430e. I bought the boat in 2019 and I was given reciepts that show that the seacocks were replaced in 2017. I have no reason to doubt that they were changed. The handles of all my seacocks are not the red stamped steel ones in the pictures of the failing units, but are the flat steel typically seen on ball valves. So my seacocks have been replaced with hopefully something that is made of the proper material, but I'm not certain that they were. This year I will change to Trudesign but I want to ask about the thru-hulls. From my observation the thru-hulls on my boat are bronze.
While I could be prudent and replace both the thru-hulls and seacocks at the same time, is it necessary to replace the bronze thru-hulls? Have you seen failures in the Thru-hulls?

If you are absolutely convinced that the thru-hulls are made of bronze, they would not need to be replaced. But since this matter could be the difference between life and death, I would buy the Trudesign thru-hulls anyway. The ball valves are a bit expensive, but the thru-hulls are relatively cheap. I sail in places with medium to low saltpercentage in the water, but my thru-hulls were corroded anyway. If you read all posts in this thread, you will discover a boat sailing in fresh water in Holland with no corrosion at all, while two other posts mentions the thru-hulls falling apart when they were dismounted. I replaced the seacocks with Trudesign in 2013, and until now I have no problems. I sold my old Maxi back in 2005, with seacocks of bronze 28 years old. The new owner still has the old seacocks fitted on the boat, now 43 years old, and still going strong. His old Volvo engine is also still working.

The 120 degree bend I used, are made by Trudesign. But these are not sold at every place that sells the valves. ![]() I bought mine here: https://www.maritim.no/trudesign-slangestuss-120- |
