OK another attempt to fix our SHURflo SMART SENSOR 5-7 freshwater pump resulted in some good information from SHURflo support. We had to go with the SHURflo SMART SENSOR 4.0 freshwater pump instead.

SHURflo support said our SHURflo SMART SENSOR 5-7 freshwater pump is too big for our boat. It is trying to push 5.7 gal of water through the small plastic water lines we have and is one of the reasons it is cycling.
Pedro said to return it and purchase the “SHURflo SMART SENSOR 4.0 freshwater pump” and it would work better (looks the same). Model # 4901-0211 Aftermarket Marine with 3 year warranty. He said Marine Exchange could get a RG2 for the return.
Also we need to replace the small water lines coming from the water tanks. This is a project we have already purchased the parts for and is on the list. It will get bumped up.
Looks like we will remove the water pump and replace those water lines and then replace the pump with the “SHURfloSMART SENSOR 4.0 water pump”. We will return the pump to Marine Exchange for a 4.0.
This part (Drive Assembly 94-030-02) includes a new diaphragm which has at least one hole in it.
SHURflo support said the reason it failed was the small intake water lines were cause a vacuum and work the diaphragm too hard and that that the time frame is about right as it will last about year or so and then fail.
They also suggested we could go with an accumulation tank and a diffident style pump.
For space savings alone we think a “SHURfloSMART SENSOR 4.0 freshwater pump" is our best option, at least we will try it first.
Note:
We decided not to go with an accumulation tank. Also our SHURfloSMART SENSOR 4.0 fresh water pumphas worked great for years now. We did rebuild it once. It works great also for fresh water wash down of oir anchor chain, 2018.
Because we were concentrating on finishing off the refer, we have put off fixing this pump situation. We used the breaker switch turning off and on the pump each time it was needed.
That in turn just caused the breaker switch to fail. JD at Downwind Marine came up with an original replacement for the 15-amp water pressure breaker. We had to hijack the blower breaker for the frees water pressure pump. Now to replace the breaker also 😀 but hay, we got a working refer!

Yellow diaphragm.
We are also buying a Drive Assembly 94-030-02 for the old RV SHURflo SMART SENSOR 5-7 fresh water pump we mistakenly bought not knowing it was an RV pump.This part (Drive Assembly 94-030-02) includes a new diaphragm which has at least one hole in it.
