38xx Shower drain / Pump-gctid810077

[capt._ron]

The pump has gotten much slower draining the tub when taking a shower. I looked for a strainer near the pump but found nothing (my 32xx had a strainer near the pump). Does anyone know if Bayliner installed a strainer and if so where can I locate it? If no strainer is in the system I may have to change out the 30 year old hose and pump, a job I would like to avoid if possible. Thank you.

I had the same problem with the pump on my 3870. The pump is a pneumatic pump the push rod inside the bellows wore out. This made it pump very slow. It always was very loud. I took out the pump and replaced it with the below item from Amazon. It cost me less than $40.00. Did have to buy some fittings from Lowes.

This unit is working very well and the admiral likes it a lot better, and that's the most important thing. No buildup of water in the tub and is much quieter.

Neat! Not to hijack (yet here I go. . .), but where is it located? I can hear it run, but haven't been able to locate it. . .

thanks!

My pneumatic pump that I replaced was located under the hatch in the kitchen. The fresh water pump is under there and so is the three way pump out valve. I sat in a piece of board to set the new shower pump system on.

Do you have a name or a part number for the pump you purchased from Amazon by chance?

I bought nearly the same one, but got it on ebay. Haven't installed yet, but I'm putting it in the master bilge compartment so I can also run the fwd a/c drain to it. If it weren't for the a/c condensate my fwd bilge would always be dry.

This is the info I have on the order from Amazon:

Amarine-made Boat Marine Shower Sump Pump Drain Kit System Shower Pump System - 12v - 750 GPH - Multi-port Inlet

I hope this will help you. Like I said, you would be standing in 4" of water waiting for the old pump to pump it out. Don't get me wrong, the pneumatic pump will last for ever. But it is slower than what we are use to and is very loud in comparison to what to the new one. Basically the new set up is a 12v bilge pump in a plastic shoe box.

Yer darn skippy it's loud! SO loud, it sounds like it is right under the tub when you flip the switch.

I had no idea that the rusty old pump under the galley was the tub drain. I just assumed it was the original water pump and was just bypassed :whistle:

When we bought our 3818 the pump was absolutely silent. Oh, yeah, and missing. The tub was draining into the forward bilge. That was one of the first things I fixed.

Funny this came up - I just had mine slow way down and being the rust ball that it is I didn't spend too much time looking for a rebuild kit.

What I was shocked was the cost for a kind for kind replacement - sorry not doing that.

Bilge pump in shoe box from Amazon will show up this week for $40. If I don't get the original working almost immediately I have a quick project to do while we are out this weekend. I know the rebuild kit if I can find it would be more than $40.

For those that have changed to this style pump - did you leave the shower switch or just let it go with the float switch and be fully automatic?

[Old_Man_With_A_Boat]

I thought about putting it on the switch in the shower that ran the old pump. But the admiral said she would like it to be automatic, so I set it up for automatic operation. To change it to the switch is not a problem. Just change the wiring. So far it is working well. I have had it in place now for over three weeks.

[Cool_Beans]

Might be wise to have a manual option in case the float sticks/fails? You could probably wire it to a bilge pump style switch. Leave it clicked over to "automatic", but able to hold the switch over to manually run the pump for any reason. Just thoughts

We dump a cup of vinegar in the tub drain once a month. Brings the drain time right back. It's probably just soap scum and hair slowing it down. There is no strainer and yes, it's loud.

[capt._ron]

Thanks JV, I'll try the vinegar and see if that works, if not it'll be new pump time.

Liveaboard here... So use the shower often, and have had to replace my pump as well. I've found the scum buildup is MUCH worse with bar soaps. Switched to liquid body soap (Dial) and no more scum buildup in hosing or tub.
