I have a 2000 340 Sundancer
The pump for my water system, cycles on (for just a fraction of a second) and then off cycles off. This occurs approximately every 30 seconds. I must be losing pressure somewhere within the system thus causing the pump to turn on briefly to rebuild the pressure. I had this same issue all 2022 season and did not find the source of the issue.
Early in this 2023 season I thought the issue (might have) resolved itself. The pump was not cycling on/off initially this season. BUT, when I refilled the tank this holiday weekend with water and I also poured an ounce of bleach into the tank (to cleanse the water) this cycle on/off issue started to occur again. I'm wondering if the bleach killed any "gunk" that may have temporarily been blocking the site of the pressure loss? Or maybe it damaged a gasket/washer?? (I'm just guessing here).
However, I "THINK" I may have found the source of the problem. I ""think"" it may be coming from my Jabsco water pressure regulator (located in the stern locker). Very late last season I noticed the (white) cap on the regulator was off and the there was water dripping out of this regulator. And the area below the regulator, in the locker, was wet and blackened (mold??). I put the white cap back on (see picture below) in April 2023 and the cycling "seemed" to stop.
However, I noticed today that the cycling has restarted (after this weekends water tank refill and bleach add) and I also noticed some drips today coming from the regulator.....See Picture
1. Has anyone had this cycling on/off issue?
2. Was the Water Pressure Regulator the source?
3. Is the Jabsco part still available for purchase? (I have the SeaRay part number)
4. Is the regulator difficult to replace (any how-to instructions)?
I'd appreciate any help/guidance/advice....... Thanks
