first check if the pump get power. I presume your pump is 12V DC. If you have a dc tong tester that is one way.Or disconnect the motor and reconnect directly to a battery. Then a more crude way to test is to take one lead off and touch it together again. If your pump is stuck but the motor is still o.k. you will get a reasonable spark. No spark: your motor brushes are worn out or your motor is toast. You have a spark your pump is stuck with debris. Try to run it reverse(reverse the power leads) and or clean it out. You can see the cutter knifes from the intake end and should be able to turn them with a screw driver. New pumps on ebay: I paid $125
Your description sounds like plumbing from before bacteria was discovered. The output from a Saniflo macerator should be sent to a foul drain or cesspit and not a rainwater drain.
Some authorities allow local rainwater runoff into foul drains but this situation is gradually being designed out.
Could be your Saniflo installation didn't meet building regulations when it was installed. The fact it has been working fine for 2 years doesn't count for anything if it doesn't.
I know nothing about the Saniflo system but I suggest you check in the supplied literature if any routine maintenance is recommended and if so I think it would be wise to do that before looking for further explanations (problems).
Bail out as much as you can through the toilet bowl. Unfortunately this is a messy job regardless and you will still need newspaper on hand.
If you lower the water level below that of the rubber gasket connecting it to the toilet though, you will be able to undo the jubilee clip holding this and slide the unit away from the toilet, hopefully without spilling much waste water.
If you can dislodge the blockage from this angle, great. If not, you might also have to take the lid off by depressing the plastic clips on each side and accessing the chamber from the top.

Sorry but they give you 8" for a reason, they did the testing etc. You might get by at 5" but that will probably just get by and limit the service life.
You need to adjust the float. Or, you can buy the complete inexpensive float valve assembly at Lowes or Home Depot and can install it in less than 5 minutes. Turn off the water supply, drain the tank, sop up the remaining water in the tank or put a pan under the tank opening for the next step, remove the valve assembly and float and install the new valve assembly with the float included. Turn on the water supply and set the water level adjustment valve to about 1/4 inch below the stand pipe overflow drain. This is done by the float assembly. Turn on the water supply. This completes the change-out.
What type of pump is it? Is it a shallow well pump or submersible
pump? Is the pump connected to a pressure tank? How have you confirmed that the pump is working properly? Is there a drain valve, and is there water pressure from the drain valve when it is opened? If the pressure tank is of the pre-charged type, is it working properly? Is there water coming out of the air valve? Are there any shut-off valves in the system which may have been turned off, preventing water flow?
You should be able to purchase this at any local hardware store.Lowes, Menards , or Home Depot. They may have to order it but I am sure that if you take the old parts they can make you a replacement if they do not have the direct replacement hose there.
sounds as if thewater is filtring back due a possible blockage do not put paper or towles in them the water expands them a causes this problem cleaning is a messy job if they are blocked disconect from toilet connection but have a bucket and mop handy
Sounds like the pump needs to be de-watered completely and cleaned. There is a pressure chamber that contains, I am guessing here since I hve never taken one apart, a float and a microswitch. If the float gets heavy with gunk or gets a hole in it, it will not float as well and will take more water in the drain pipe to cause it to rise up and activate the micro switch. I don't know how hard it is to disassemble these units but hope it is fairly simple since they are pricey. You said it was only on a sink, not a toilet or both. It is possible that grease has built up (the gunk) and a hot water flush may do the job for you but it will take a lot of hot water flowing through the grinder, that of some grease dissolving drain cleaner.
Sure hope you got that fixed. If not you can try to make the rubber more flexible with heat, either a towel/rag soaked in hot water and then applied to it for a few minutes or a hair dryer on low blowing on it for a few minutes (be careful you don't burn the rubber).
The "tank level" switch is stuck on. You may be able to clear it by cleaning the system/pump with a water hose (outside of course) so you will have to take the system apart then give it a good cleaning. May not help but at least you will have tried.
