What is the function of foot valve in the pump?
A foot valve, in relation to a water well, is a check valve at he bottom of a well to keep the water from running back into the well from the pump when the pump is not running. If the check valve does not hold the water the pump will lose it's prime and will not pump water.
Should water of any amount be in the sump pump and would it have anything to do with my kitchen pipes being blocked.?
If you have any water at all coming into the sump, there will always be a little in the bottom unless it stays dry long enough for it to evaporate. The design of the pump doesn't let it pump the last little bit out. If there is not a check valve in the discharge pipe, what is left it the pipe going out will drain back into the sump. If the discharge pipe is connected to the house drain and there was not a check valve in that pipe, depending on where the kitchen clog is, the sink could drain into the sump.
What are the Advantages of reciprocating pumps?
A reciprocating pump is basically a piston in a cylinder with 2 check valves in ports in front of the piston. When the piston is moving back in the cylinder, a check valve allows fluid to fill the cylinder from the intake port, while the discharge port is blocked by its check valve. When the piston goes back the other way, the check valve in the discharge port allows fluid to pass while the check valve in the intake port closes.
Your grinder pump runs properly and when the pump shuts off a loud slamming noise occurs which the plumber states is caused by the check valve closing Is this normal?
Yes if the installer used the wrong type of check valve as the flapper is reseating
Why centrifugal pumps wouldn't be used for pressure transmission?
Centrifugal pumps are used to transmit fluid from high suction head to low delivery head.....by converting the kinectic energy into pressure energy which raises the fluid up to the delivery head....... pressure transmission doesn't take place but fluid transmission takes place...
What location must a check valve be placed?
Generally, placed close to the supply discharge of the pump.
In sump pump discharge line check valve is installed before or after gate valve?
after gate valve, because when you want make maintenance for sump pump , you don't want all water in the pipe drop down sump pump - gate valve - non return valve
What does the check valve do in the sump pump?
It keeps the water that is pumped out from flowing back into the sump when the pump shuts off. Most sumps discharge several feet above the hole the pump sits in. If there was not a check valve the sump would just refill and pump out the water over and over.

Sump pump continously runs?
The sump pump could run continously for 4 different reasons:The switch is bad. The switch is what tells the pump to turn on and off, and it is possible the switch is stuck in the "on" position.The pump is undersized. If the pump is undersized the pump will not be able to keep up with the incoming water and it will continue to run.The pump discharge is restricted. The discharge pipe could be resticted, kinked, or blocked, so confirm there is flow at the end of the discharge.The pump is airbound. A pump gets airbound when the pump looses its prime and is caused by no weep hole on the discharge piping. A check valve has to be in use for this scenario to develop.
