I'm thinking about installing a shower in my norman 22 widebeam.sorted water/ gas / flue.my only problem is the waste water I was thinking of directing a flexible wastepipe as close as I can get too the bilge pump under the floor and pumping out the water by said pump.opinions please on feasibility.

Whatever pump you go for it is best to contain the water in a small sump and not let it tun into the bilge to stink.

I fitted a gulper in my 32. It saves having a sump and you can get the shower tray lower because the gulper can be put any were because it sucks the water up. |

The shower sumps have a coarse filter cylinder on the inlet. It's a 2-minute job to clear them once in a while especially if you have left a floor panel easily removable above.
My shower sump and pump is now 12-years old and, touch wood, has never given any trouble. |

£12.99 for a pump Deano - hardly breaking the bank! How much is the Gulper?
And how high is it if one is chasing headroom inches?
You can always stick the little pump inside a bag made from her Ladyship's cast-off tights foot end, then all you do it take off the bag and throw it away periodically. How many bags are you going to use in a season? You get two for every pair of tights, how many of THOSE does she discard in a year?
Save a penny - spend a penny, save 100 pennies and buy a tinny!

The downside of the small bilge pump in the sandwich box style pump out systems is that it will eventually get clogged with hair and soap scum. Not a difficult job to clear.... but unpleasant. The float switches and little pumps fail with annoying regularity too.....
Go for a Whale Gulper...... they appear to last very well, almost impossible to block... you just have to get over the sound of the copulating frogs.... I fitted one 6 years ago..... it has been trouble free.... and gets a fair amount of use.

I did this for a chap on the Dawncraft Owners club on Facebook - same crowd that used to run the web site.
He asked the same question - having done several on my own boats I did him a sketch. You have an easier time of it because Normans have a deep vee hull so a lot more space under the floor to create a sump. Trust me - keep the deepest part of the sump as small as possible commensurate with the bilge pump size, that way you can pour or use the shower to flush it with clean water or it will stink.
Automatic bilge pumps are £12.33 on ebay, use plastic tube and buy a plastic skin fitting and install it above the waterline of course.

I'm not an expert - I'm not even well-informed - but it seems counter-intuitive to have a system to keep your bilges free of water and then discharge waste water into the bilges, anyway. I'd be following the advice of others and looking at systems which remove the shower water direct. |

I had a bilge pump and float switch under a slatted floor on my old norman 25 in the shower and it worked well but there was always a bit left to clean out with a sponge, I had one like the first link on my RLM 31 and that was better, as Fred says shower water will soon start to smell.
The alternative is a diaphram type pump switched on when you shower as long as you don't mind the sound of a randy frog, this is what I have now on my princess.

You can make a much better job of it by using a shower sump with built-in float switch and pump:

Even cheaper Chinesey ones on Ebay:

Drawbacks of doing what you suggest are that wherever you site the waste pipe the water will spread throughout the bilge, the pump will run for long periods draining the battery and never completely clear it. Dirty soapy water in the bilge will stink after a while. You will never be sure if water in the bilge is from the shower or from leaks elsewhere which may even be indication of something serious. Best to keep your bilge pump ready and waiting for its intended use!
The shower sump unit pumps are fairly low powered and operate only while water is flowing into them through a built-in float switch so are light on battery use. They are sealed units (top can be removed for cleaning) so no smell.
