The pump turns back on after it has cooled down enough. If the pump gets too hot the thermal overload protection will turn it off until the pump cools down (to prevent damage to the motor). "What does the automatic reset thermal overload protection do?"Ī.
AIR ADMITTANCE VALVE PROBLEMS WITH NO MAIN VENT INSTALL
The right way to go is to install a non-mechanical vent, all the way to the roof, and as per your local codes. We have had people write us stating that when they installed an air admittance valve the flapper in the valve can chatter and create vibration. We always recommend installing a vent all the way through the roof (and as per your local codes). Although some people have installed an air admittance valve on the above systems, we will never suggest or recommend that you do so. "Can I safely use an air admittance valve (or "auto vent") on any of the above systems?"Ī. The installation for each unit is similar the check valve hinge must be at the top. It is recommended the check valve (or check/ball valve combination) be mounted vertically, however each can be mounted horizontally. "Can I mount the check valve horizontally?"Ī. If you install a pipe with a height of 20' straight up from the pump, while the pump continues to operate, water will just stay at that height in the pipe. If you install a pipe 19 feet 11 inches high straight up from the pump, water would still trickle over and out of the pipe. It means that the pump cannot pump higher (measured vertically) than 19' 11" (with no friction loss taken into account). We have sold many of these Little Giant brand sewage ejector packages with MANY satisfied customers!Ī. Includes pipe flanges (2" or 3" vent - 2' discharge) and cord grommetĭue to the size and/or weight, these sewage ejector packages do not qualify for 2nd day shipping. Replacement Part for above sewage packages With PVC compression check/ball valve combination With full-flow PVC compression swing check valve We recommend the check valve or check/ball valve combination be vertical mounted. The check/ball valve combination allows you to stop backflow from reaching the sewage package while servicing it.

The sewage package #SE-9S-SMPXRT-K is an upgrade version that contains a combination swing check valve and ball valve. The sewage package #SE-LGSMPK comes standard with a full-flow 2" check valve. The vent outlet through the lid has a 3" opening and can be sealed with a 3" or 3" x 2" non-threaded rubber grommet. The discharge pipe passing through the lid is sealed with a 2" non-threaded rubber grommet. The sewage is pumped out of the pump, through the 2" discharge outlet, through the check valve, and into your regular drain line. When the fluid level rises high enough it triggers the float switch to turn on the pump. The side inlet can be bushed down to 3" if needed. Your fixtures are plumbed to drain into the basin through the side inlet set up for 4" drain pipe. The basin, with the pump in the bottom of it, is recessed into the floor.
The laundry room is in a little addition at the back of the house. As far as I can tell, there is no ventilation on these drains (photo below) it looks like a stacked pair of S-traps. So I checked the plumbing and it looks like both the washing machine and adjacent wash basin drain into the same pipe. I did some research online and found that lack of drain ventilation could cause both of these problems. occasional "musty" smell, which seems to come from the drains.I bought a new house about a month ago, and have since noticed some plumbing issues in the laundry room:
