Non Return metal foot valves now scrapped on both Whale Hand and Gulper electric, manually operated pumps, replaced with plastic strainers only no valve. The pump tails are now movable so each can be placed in a bucket for independent testing without the need to pull fuses.
The faulty Rule
2000 second one, (first stopped when switch failed in on position the alarm
stopped working after 5 minutes and ran for 9 hours dry) has been swapped for a 1/4 of the price
Asian knock off. To see if that is any better or worse than branded unit. Have a new Rule 2000 in storage
just in case. The knock off plugs straight into the Rule base.
Replaced the Whale electronic level switch, because once it switched on would not turn off. That is the third replacement on the boat in 3 years.
First one switched on with no water and stayed on.(caused pump and alarm
Second just did nothing when tested one time.
Third turned on with water but would not turn off unless it was de-powered.
I guess I need to test theses things more often, the sad thing (maybe not) they have never worked in anger. The only running they have ever done is testing or during sensor
