Sump Pump hose length - how long of a hose/pipe can I safely connect to my sump pump without risk of damage or wearing it out? My current setup is that the pump, pumps up a PVC pipe (9') then out to the exterior which is 15', from the exterior I have about 30' of PVS which is sloped, then about 90' of flex sump pump hose to get the water away from the house. Am I putting too much stress on the pump?

Also, does it help to have the PVC pipe vented to prevent vapor lock or doesn't this matter?

Thank you for your help.
