    Posted: 25 June 2018 at 08:54
Hi

I have a water pump on the head to be used to flush the water after a shower. The make is Flojet.
Lately when I clean the filter of this water pump the water is no longer flushed by the pump.
I need to prime the all system by placing a hose into the sinkhole on the floor and connecting the pump.
Sometimes it seems that I need also to close the sea valve of the sink for the operation to succeed!
After this the water is flushed as it should.

Any ideas on how to improve this?
Is there anything else that should be cleaned? The system is 11 years old.
Could it happen that air is entering in the system because the filter lead is not closing properly?


As a remark it seems that the water pump makes now less noise than it did in the past!

thanks

My H370 came with a waterpump for the water and same type pump for the shower drain. Useless.
I changed to a pump made for shower drain. Have showered every day and never had to do anything.

Hi sea-u.

Have also installed a accumulation tank and want to install the exact same pump on your photo.

But I have issues getting to fit in the small area.

Could I kindly ask that you post some addtional photos of your installation?
Maybe it could be in the 370 section?

Kind regards

Are you talking about the pump that empties the water from the shower tray and is mounted under the floor boards in the saloon or another pump.  If it is another pump, can you describe its layout in more detail.

Hi

thanks for the answer.
I was "talking about the pump that empties the water from the shower tray".
In the 342 is mounted under the sink in the head.

It seems that some times isn't able to empty the water, and to solve this I need to place a hose a flush the water through the system. I think this mainly happens when I clear the filter in the pump.

In our 341, the shower pump is underneath the floorboards in the centre of the yacht.  So after we have cleaned the filter, the next time we have a shower the water automatically runs down into the pump and primes it.   It sounds like that on your yacht there is very little drop, if any between the shower tray drain and the pump and so your system is relying on the pump being able to self- prime itself, initially pumping air and if the pump is a bit worn, then it may not be able to do this too well. 

As you say, firstly check the filter cover is sealing on the pump body, check the O-ring and put loads of Vaseline on it.  Perhaps you may have to continue to prime the pump the first time after you have cleaned the filter in the matter you described.  What you could do is put a non-return valve, as low as you can,  in the hose between shower drain and the pump, so that once it is primed, the pump continues to have water in it for future showers and should self prime.  This valve will also stop the annoying situation that when you switch the pump off, having drained the shower, some water then runs back out of the drain.

As Sea-U correctly states, the shower pump mounted by Hanse is of a type that is not supposed to be used as a drain pump for the shower. After several years of too frequently rinsing the damned filter,  I changed to a "Gulper" pump, which has no filters.
In my 400, Hanse Werft has succeded in placing the pump (now removed), where service is almost impossible, you can not see the filter-house, but have to feel your way to unscrew the assembly, hoping that the house, the filter or the o-ring will not fall into the void between hull and interior. My advice to you all, is to buy a "Gulper", the sooner the better. Do not wait as long as I did.
