possibly in the holding tank

Look under the camper and see where the pipes goes. Also Black is usually a larger pipe then the others.

for the coach normally under the rear bed close to water tank

There should be plugs underneath the camper to drain the water tanks. Remove them and let the water drain. There should also be a plug on the water heater, remove and let water drain. There is also a bypass valve on the water heater to divert water away from the heater, turn this to bypass. After the water has drained replace the plugs except the water heater plug. The heater plug can stay out. Fill fresh water tank with RV antifreeze, usually about 3 gallons or maybe a little more for larger RVs. Run pump opening faucets one by one till water is forced out and the antifreeze flows including toilet. When antifreeze is flowing out the faucets close faucets and shut off pump. When pump is shut off open faucets, the antifreeze may get slushy in very cold conditions but wont freeze and a little may drip out of the faucets. The water heater may still have a small amount of water in it but shouldn't be a problem if you leave the plug out. Make sure the blackwater and greywater tanks are empty, you can dump a little antifreeze down the drains and toilet to make sure the sink traps are free from water and the blackwater tank has antifreeze in it. Other than that just shut the propane tanks off and youre done. Try to leave a couple of windows cracked slightly to promote airflow and reduce condensation inside the camper

look in the cabinet work underneath the sink.look also above your potable water tank inside the rv. maybe look around inside and out of the hot water heater.

Changing out the water pump is easy 4 screws and three to four water lines that have hose clamps. The water pump should be under one of the pull out beds and or under one of the chairs. Where ever your fresh water tank is at the pump should be right above it. You will have to take a panel or two off to aces the water pump. Hope this helps you out

Typically these filters are located under the sink in the kitchen.

That should be easy to locate. Outside, down low. Usually black, 3" diameter. Has a cap over it (or should). The unit will have 2 pipes running into it. One usually 1 1/2" or 2" for the grey water and a bigger 3" for black water. Made out of PVC plumbing pipe, just like in a house.
