Hi all.
Does anyone have a Benny Oceanis? If so... Do you have the same problem as I with the waste water from the heads basin taking FOREVER to run away? I've dismantled it...blown it through... there doesn't seem to be any sort of blockage.
I can only surmise that it's due to the right angled joint at the basin waste end that's causing it. If I'm right then the only solution would seem to be to fit a straight through joint. Has anyone else had this problem and have they tried to fit another joint...and did it work? Or did they find the problem was elsewhere?
Most grateful for comments.
Thanks.

I ahve a 311 and dont have this problem. On mine the basin is drained by a straight pipe to the through hull fitting ( as far as I remember). It takes a few seconds as the outlet is under water and it only drained by gravity, but is not particularly slow. If you want me to do a test and see how long it takes to drain a full basin of water - then I'm more than willing; I shall be at the boat tomorrow (Friday).
Which Ben do you have??

Never mind...I totally misread his question...thought it was the toilet bowl taking forever to completely empty.

Alan,
It's a 36CC. 2002 model. I'll try Sonsy_lass's suggestion but if you can be bothered I'd be interested to know how long yours takes to empty. As the bowl size may be different it might be better to time a given amount of water...a couple or three pints, for example.
My galley sink is a straight-through fitting, and that drains away in seconds. Admitted...the pipe bore is larger...but for all that ....
I'll time mine as well, this weekend.
More interestingly though, I'm encouraged to find that other models have a straight through fitting. Probably means I can get a straight through to fit mine.
Please PM me after the weekend with your findings...and thanks very much.

Hi Cliff,
Well I just popped down to the boat (10 mins walk) and did the test. In the heads it takes 7 seconds to drain 1.5 litres. So, say 4.5 secs per litre (around 8 secs a pint). In the galley it takes about 6 secs for 1.5 litres; so very similar. These times are approximate and I did the test with the valve closed, tipped the water into the basin and then opened the valve (didn't use the basin plug).

However, I also checked the fittings and in the heads (contrary to what I said earlier) the attachment is actually a right angle to the sea-cock; in the galley it is straight and the also in the galley the tube is a slightly larger diameter.

How does 5 secs a litre compare with yours??

Alan.
