Question

sewage ejector pumps do not need an inlet pipe a trap a discharge pipe a vent a 120 - volt electrical supply question 6 all of the following are possible cross connection situations except bidets extendable faucets on kitchen sinks water supply connections to heating boilers trap primers floor drains with no trap primers

Explanation:

1. For the first question about sewage ejector pumps: A trap is not needed as it can cause blockages and interfere with the pump's function. Inlet pipes are needed for sewage entry, discharge pipes for sending sewage out, vents for air - flow balance, and an electrical supply is needed to power the pump.
2. For the second question about cross - connection situations: Trap primers are not cross - connection situations. Cross - connections involve the potential for non - potable water to contaminate the potable water supply. Bidets, extendable faucets, water supply connections to heating boilers, and floor drains without trap primers can all create such risks.

Answer:

1. B. a trap
2. D. trap primers
