SO 36i water pressure

[timturner]

The pressure to the shower head is insufficient to keep the shower head switch engaged to shower and also makes the bathing shower a joke. Have Jeanneau resolved this in the 2008 models? It seems that the pressure switch is just not sensitive enough to make the pump maintain the pressure - it really never was "fit for purpose"!

Hi. We have the same problem with our 2007 42i I think the pump needs to be more powerful.

Guys

The pressure on our shower is fine I even use the shower rather than the onshore services (we do use Ecover products).

The pump only turns on when the pressure needs rebuilding in the system.

So far I have yet to find anything wrong with the boat.

Happy sailing.

Geoff.

Geoff is obviously happy with his "eco" showering and the rest of his boat, good. The real purpose of my forum message is whether it is a 2007 boat problem or has it been rectified for 2008 or later built boats - my SO 36i hull is number 96. For example, I did complain that the saloon rooflight would not open against the kicker, it had been fitted with the hinges towards the stern. I subsequently found out that production models are now being fitted with the hinge nearest the mast so that it will open! My agent was able to persuade Jeanneau that they shoiuld refit mine and it was done very nicely, full marks for common sense prevailing. I have been in retailing for over 35 years and I have seen this type of problem occur with early production models of many things and inevitably, my company was obliged to help resolve these issues with any unhappy customers. Complacency has never progressed anything.

Hello All,

First the shower issue. In my view the shower rose fitted to the 36i is NOT suited to a boating shower. Firstly, even in spray mode in my view the water flow rate is too high. Yes you can turn off the tap a little but a nice spray is always preferred even if the water droplets are very fine.

We find it very frustrating that the shower rose keeps reverting to single flow instead of shower spray mode. That is a real pain. It looks great at a boat show but in practice I don't think it is the best suited shower rose for the job.

Secondly, yes the hatch on the latest models is reversed so that the hinges are closer to the mast and hence it can open in reverse. That is fine unless you live in a really hot climate and you desperately want to have some breeze through the saloon.

We asked for our to be reversed from the factory (so it was facing with the opening forward). Our request was overlooked and it arrived opening toward the rear. We tried all sorts of wind scoops to get air down the opening and in the end got the hatch reversed by a local shipwright. We are now very happy, however we intend to lift the kicker onto an open cheek block hanging from th boom when at rest so we can open the hatch a reasonable amount when at rest.

We will probably not do anything about the shower rose unless we see one that perfectly suits our purpose. We have resolved the hatch issue so when on a swing mooring or anchored, we get a lovely breeze into the saloon.

These two very small issues don't detract from our overall enjoyment of this great value yacht. ;D

Regards,

Trevor

CLEARLY THE PUMP DESIGN NEEDS TO BE RE-ASSESSED. IN THE MEANTIME, TO MAXIMISE FLOW. LOCATE AND ENSURE ALL STRAINERS FILTERS ETC ARE REGULARLY CLEANED. (THEY CLOG UP IN NO TIME DUE TO INADEQUATE FILTER SURFACE AREA) THE SYSTEM IS ACTUALLY QUITE ADVANCED FOR A YACHT. THE PRESSURISED WATER SYSTEMS ON MY JEANEAU SO 37 ARE FITTED WITH AIR ACCUMULATORS WHICH ASSIST TO PROVIDE INSTANT FLOW WHEN A DEMAND IS MADE. THEY ALSO DAMP OUT PULSATIONS WHICH USED TO DRIVE ME NUTS WHEN I HAD A B.....EAU 321 (APOLOGIES FOR THE SWEAR WORD). GETTING BACK TO THE SHOWER PROBLEM - THE SHOWER CABLE IS NOT RIGID ENOUGH. WHEN THE HEAD IS MOVED AROUND THE SHOWER TO RINSE OFF, THE SOFT INNER CABLE SWAN NECKS, CUTTING THE SUPPLY AT THE BASE OF THE TAP WHICH IS MOUNTED ON A HORIZONTAL PANEL TO THE REAR OF THE WC (C.MON JEANNEAU, SPEND A FEW MORE PENCE ON A STRURDIER CABLE!)

My Jeanneau 36i left the factory in July this year and is now sailing in the Gulf of Thailand. The shower problem still exists. The rear facing hatch is no good for catching the breeze at anchor in this tropical climate and I would have preferred the previous method. These are two minor problems in an otherwise splendid boat.

[Trevor]

Hi Velaroo,

It seemed quite straight forward when we had our hatch reversed. The job was very neat and no leaks have occurred. I think you could probably reverse it yourself without too much stress. I think the sooner the better though so the sealant doesn't have too much time to go rock solid and make it difficult to remove.

The front facing hatch is MUCH better in hot climates.

Good luck,

Trevor

With our recently commissioned 36i, our shower would also switch out of 'spray' mode as the pressure droops before the pressure pump kicks in again.

As this can be a little annoying, I pulled apart the shower rose to see if I could modify it some way to keep the 'spray' mode on. I found that it is a very easy job to disassemble the shower rose and remove a spring which forces the shower rose back to 'single' flow. Now, with the spring removed it no longer reverts to 'single' flow automatically, but it can quite easily be switched between 'single' and 'spray'. It now stays in 'spray' mode for as long a shower as you want, regardless of the pressure drop. We're much happier with it this way.

Cheers,
Geoff.

Sounds a great trick

I will try the mod on our 39i this weekend

Although our 36i is in winter storage for the next few months, I will attempt to remove that spring,

Thanks for the information,

Happy Sailing,

Hello all,

I own a 02 SO43 and have been reading this thread. One of the things that I noticed on my boat is then when the shower head is pulled out all the way and the hose gets twisted, the twist in the hose went down through the shower hose penetration. The next person that used the shower pulled the hose all the way out causing a kink in the shower hose where it couldn't be seen. The kink in the shower hose caused a reduction in water pressure causing similar symtoms. I had to physically remove the board to get at the kink and untwist the shower hose. A simple thing to check out.

[timturner]

I started this subject and will definitely try this when we launch in the spring. Thank you everyone for the ideas, especially Sailingpages. What a great Forum, Tim

Hello all,

We are one week into a 3 week holiday on our 36i and I have just performed the EXTREMELY simple modification to our shower rose. It works like a charm.

Many, many thanks to sailingpages for this outrageously simple modification that means so much to us. ;D ;D ;D

Regards,

Trevor

HI TO ALL THOSE HAVING PROBLEMS WITH WATER PUMP PRESSURE, I HAVE FOUND THAT MOST PROBLEMS ARE DUE TO EITHER NO ACCUMULATOR TANK OR NO AIR PRESSURE IN THE TANK TURN OF POWER TO PUMP DRAIN WATER FROM THE PRESSURE SIDE OF THE PUMP AND PUMP THE TANK WITH AIR TO ABOUT 18PSI THAT IS THE ACCUMULATOR TANK NOT THE WATER TANKS OF COURSE THE BLADDERS IN THE TANKS WILL LOOSE AIR PRESSURE OVER TIME, ALSO YOU CAN ADJUST MOST PUMPS PRESSURE SWITCHES WHICH WILL ALSO HELP TO ELIMINATE CYCLING IF YOU DON'T HAVE A PRESSURE TANK IT IS VERY SIMPLE TO FIT JUST TEE IT INTO THE DISCHARGE SIDE OF THE PUMP THEY ARE READILY AVAILABLE AT MOST GOOD COMMERCIAL PUMP SHOPS
IF ANY ONE WOULD LIKE TO TALK TO ME ABOUT THIS SUBJECT DON'T HESITATE TO CONTACT ME PERSONALLY REGARDS TO ALL BILL GORDON WERRIBEE VIC. AUSTRALIA NEW MEMBER AND NEW SECONDHAND SUN OD. 49 CRUISING EAST COAST OF AUST.

You are correct that the shower hose can often get twisted, but sometimes the pump pressure isn't quite enough to keep the shower rose in shower mode. There is a small red tab tape on the bottom of the frsh water system pump. The best way to access it is to undo the 4 screws securing the pump and tilt it out to expose the little label. If you peel this label off there is a small allen key screw. Tighten this about one turn clockwise and remount the pump. That will usually increase the pressure enough to keep a proper stream at the shower rose.

Good Luck!

Lee

They changed the shower head in my boat twice before they got it right. It's a known issue, but it's not with the pressure, it's with the shower head design. Mine works perfect now, but it took some "pressure" on the dealer to keep them on it until it was fixed.

PM me and I can refer you to my dealer for more info.

I have come across both problems ie. deck hatch and water pressure.As to the water pressure I found that the shower head at the transom had split, why I dont know ,but this is the second time it has happened.It was replaced the first time and as we have just launched we will be bringing it to the attention of the agent. About the hatch did you have to pay to have it turned or did the agent cover the cost

[dan]

Hi Guys Im relatively new to the forum. I too excperienced the same problems thet you guys are having on our 2008 42i.

As a plumber and heating engineer i was not prepeared to put up with fluctuating water pressure. I made lots of enquiries and got nowhere untill i had the pump assembly out and examined how it all worked.

Underneath the pump body, you wont see it whilst its installed, There is a tiny allen screw which adjusts the pressure on the delivery side of the pump, ie going out to your taps. You need to turn this clockwise 4-6 turns and the pressure will increase and the shower heads will spray away for ever or untill you tank runs dry!!

[dan]

NAC.

We have had 3 new transom shower ours split every year caused by them freezing up.

[SteveT]

NAC,

On a similar thread, we had to replace the mixer tap on the transom shower due to frost damage. I fitted in line valves the the hot and cold lines to be able to isolate the shower and also allow me to completely drain the mixer / shower head at winter layup.

[jdathena]

how do you pump air pressure in the accumulator pump?

[MalcolmP]

On our 39i I have tried a car foot pump but not convinced it improved things. I am planning to dump the OEM pump and pressure tank and replace with a higher rated unit that doesnt need the tank - think it is Shuflow that have these
