Customer had clogged mainline to septic tank. Pulled lid and found normal level and clear inlet baffle. Used video inspection equipment to find clog. Line dead ends with a capped tee at 3ft with sewer main from home coming in at left. Could not get drain cleaning equipment to make turn. Appears to be cast iron and maybe some clay sewer pipe.

Customer has extra and will apply until sewer is replaced from foundation to septic. Put down utility locates mark for future excavation of sewer.
Customer reported no water pressure at half the RV sites. Inspected well house and had water pressure at pressure tank. Pressure tank is 80 gallon. Turned on gate valve in meter box outside of well house that controls flow to sites. Water was seen running from standpipe valves at half the sites. Closed off individual site water valves and was able to get pressure at remaining sites. Individually tested each site and had good pressure at all. Well pump pressurized tank and turned off. Pressure gauge was at 100 psi with a 60/40 switch. Pressure gauge is probably damaged. Pressure tank is undersized for application. The well cannot keep up with everything open at once. Customer is going to be moving well house in near future.
