Thetford makes good pumps. No pumps last forever, actually only 4 to 5 years of constant use because the pump sucks air at first startup before pumping fluid. Air ruins the pump. The pump also collects sand (small tiny particles) which act like sandpaper and ruins the shaft, and impeller, etc. It's cheaper to buy another pump than to fix it, because more importantly you won't find parts to fix pumps. whether RV pumps, or Fountain pumps - the reason is the pumps require to be sealed - factory seal. So no one will carry parts.

My water supply pump to house works but does not pump water from tank to house

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?

How can you tell if your water pump is even working

Water pumps FYI

A belt drives your water pump, most are the same belts that turn your altenator and air compressor. Some water pumps are turned by the timing belt. But if you can see that your belt is working the water pump, altenator and compressor, its working. If you had a water pump powered by a timing belt, you would not be able to start your car if that belt stoped.

Water pumps never stop working, they are direct shaft driven.

The only thing is they do start to leak after they get older, then need replacing.

Check the thermostat first. Follow top water hose from the radiator to the water pump. To check for problem with water pump see if you see anti-freeze somewhere leaking or do you hear a strange noise. Also check your top and bottom hoses.

Sump pump not pumping water properly

If your pump is turning then something is stopping the water from being removed. If you can see the pump check to see if the water is becoming turbulent when the pump kicks on? If the water doesn't appear to move or is moving only a little then either the pump impeller is damaged or the screen that keeps debris from entering the pump is clogged.
If it's never been cleaned it is most likely just a clogged filter screen. Clean it and it should work fine. If however the screen is clear then it is either a blocked line or a bad pump. And yes a pump can still run and not pump, if the impeller is bad.

I have a flotec water pump that sits on top of my pressure tank, pump worked ok last season, and when we tried to prime the pump to start this season, it wont pull water up from the well pipe, pump will...

if the pump is working correctly, it can either be, need more water to prime it, or something in the well, such as low water, plugged filter, etc....sometimes when you have a system that is intermittently used, it can take 20 or 30 minutes of continuous priming to get it to pull, enough water to maintain the prime.
