2007 4460... Forward head sink's sump pump is running every 3 minutes. Is it using the forward shower sump pump? I have looked at that visually and don't see a large amount of water in there but not sure on further diagnosis. Thoughts?

Forward head sink will most likely have the shower also plumbed into sump pump. Sounds like the anti drain back valve in the discharge of the pump clogged or hardened from someone pouring bleach into drains! Never use bleach into sump pump drains, the Cl will harden the natural rubber check valve and it wont prevent back flow from the discharge hose/thru hull fitting which would cause your pump to keep cycling. Dont hink you can just gt a anti back flow check valve so best advice is get a new electronic float switch operated sump pump. We went through this twice in last 6 years, no bleach in drains, use H2O2 (hydrogen peroxide) to clean sump, check valve, and drain lines.

Seasunofthesoul,
On my 4460, one year older than yours, the sink, shower and forward air conditioner all ran into the forward Sump which was located in the access hatch on the floor of the Main berth, just outside of the main head and shower module. On my 4460 that sump always ran in short spurts rather than longer runs. I think it was due to the electronic float switch that is used in that model sump along with the fact that the sump holding tank is very small when compared to the rear head and sink sump. I was going to swamp it out with a whole new sump mechanism with a bigger holding tank after my first year of ownership, but as you know there isn't much space in that forward hold if you have a bow thruster. Not sure if it is any better without the thruster either. I couldn't find anything that would fit down there which was any bigger than the one I had.
So it running frequently is to be expected. I'd also order a spare electronic float, as on my boat I ended up replacing one of those two electronic float switches in the forward or aft sump once a year. After having one fail with no spare, I always made sure I had a spare on hand and order a replacement the day I ended up using the spare.

Good news: It appears to have just been a dirty/clogged sump pump. I was able to figure out how to pull it apart and clean it all out this morning and I think it’s all good now. Haven’t had to do that before, but it’s good to know for the future

Well I should have mentioned that cleaning that little clear mesh tube is a pretty regular thing if you don't want the sink or more importantly the shower to back up. However, even with that clear, I think that sump is really too small for use with the shower up there. It ends up running multiple times a minute, instead of just a few times during the course of a shower.

Sump pump running is most likely a function of how hard and how long you take a shower? We have had electronic sump pump switched units for about 3 years, no problem, but, we pour about a pint of H2O2 ( hydrogen peroxide) down all drains once every month. Dont use bleach! Also, dont wash any greasy dishes in sinks, the grease will solidify and cause switches to malfunction and plug anti drain back valves in pump housing.

GoFast, my issue with my 4460 was the size of the sump enclosure. The pump was fine other than the electronic float switch failing. Maybe hydrogen peroxide would have helped with that, but the enclosure should have been bigger for the function it was supporting. The sump enclosure was no bigger than a 1/4 gallon, so the pump would go on for about 10 seconds, stop for 10 and then back on. I didn't think that was very effective. Having a sump that held at least 3/4 fo a gallon would have put less strain on the pump starting and stopping so much.

How long do you take a shower? When son takes a shower uses minimal water flow and pump does run about ever 30 seconds or so. Reduce water flow, soap up after getting wet,turn off shower, wash, then turn faucet back on to rinse off. Too many folks think they are at home with unlimited water supply (hot and cold), matter of experience of using a shower on a boat?

Gofast, I hardly use any water, and I have turn off switches at the base of the shower wand. I’ve been boating for over 50 years, and I know the limits of working with a limited supply of water. With that said my wife followed the same protocol but she has long hair and it takes smite to get the soap and conditioner our. It just never drained fast enough to be honest and the sump size was way too small for a shower. It only hold about 16 ounces before it pumps and then waits till that 16 house fills again.

OK, dont have a wife with long hair anymore  . Put a small pad on the shower floor drain to catch long hair. Maybe look at a sump pump with a higher flow capacity (GPM) rating than what you have now? i have been boating for 54 years but our 4160 is the first one with a shower and sump pump (actually two showers and two sump pumps. In our fresh water lake actually easier to jump into lake, get wet, back up to swim platform, soap up with liquid hand soap, scrub off, jump back into water, and back out to dry off? No, dont think we are polluting the lake, never too dirty when doing this? |

I purchase. a new complete Rule unit from Boat ID for our 2007 4460. It was bigger than the original unit and we have the bow thruster so it took a little wiggling to get it in and I didn’t anchor with all 4 bolts but it seems to work very well. It’s a 13.3 GPM model. As posted above, got to keep the screens clean and make sure nothing builds up in the float switch that causes it to not move freely.

if I still had my 4460 I would be making this change! I looked and couldn’t find something that would fit well. clearly, there was something out there. I think this is a nice upgrade.
