Shower Drain Pump Removal
« on: June 02, 2022, 10:43:35 AM »

My 1990 MK 1 has a PAR 37202 pump for the shower drain. It has stopped working, motor still runs but no suction. It is located under the head sink and the only access is thru the door by the thru hull for the toilet, sink drain, and raw water inlet.
Access is very limited. I am wondering if anyone had removed this pump, and have an suggestions on how to do it. I have thought of removing the small holder for the t-paper and am wondering if that provides any better access.

Steve, you may have considered these already:

1.  take the door and frame off, makes the hole bigger, lots bigger

2.  check the check valve in the hose from the shower sump, it may be blogged, clogged or collapsed if it's the OEM Shurflo check valve; I replaced mine years ago

Yes. On a MKl, it will help greatly to remove TP box. Also, consider installing a Beckson access port on your head bench for better access and storage space.
This pic. was taken while installing my Raritan Marine Elegance electric head. That is the raw water pump for it not my shower pump. You can’t see shower pump in pic, but I have replaced it with a centrifugal pump.

Steve : Do as Stu suggests and check that PAR one way valve -I'm sure it's clogged!! 

Look for my Mainsheet tech note article on Installing a Strainer (w/pictures) in that shower drain line.  You'd be surprised all of the "fuzzy Wazzys" that that strainer catches!!  :thumb:

Holger,

I believe Ron is referring to this one:

https://c34.org/mainsheet/pdf/1999_no1.pdf

How did I find it?  I used the Knowledgebase and did a search (ctrl-F) on shower, which led me to his Feb. 1999 Tech Note. 

Between that and my earlier links, they should explain it all.

I have often recommended that folks use the Knowledgebase to find Ron's articles.  He's written so many but never provides links.  Can't say I don't blame him since he's written so much for so long, but it can sometimes be frustrating.

Here's the How To on the Knowledgebase:

NEW!!!-Jan. '07 -: Tech Notes, Projects, and FAQ Articles KNOWLEDGEBASE & Index http://c34.org/bbs/index.php/topic,3362.0.html is also helpful.

Hogler : I looked thru the early 1987 -1999 and that article must be in the years 2000?  Probably in the mid 2000's ( I don't have those MS issues )

What I did was install a small PAR strainer ( 3"? high w/fine screen) in the 3/4" shower drain line just before a new one way valve (same line).  The PAR strainer has a screw ON dome so I calked the base to the hull.  That stopped ALL of the backflow and kept the one way valve clean!!  An easy fix!!
