When backwashing a pool, you typically shut off the outlet. This is because backwashing involves reversing the flow of water through the filter to clean it, and by closing the outlet, you prevent clean water from flowing back into the pool during the process. Always follow the specific instructions for your filtration system for best results.
What else can I help you with?
Is there anything else you need to do after cleaning cartridge filters and putting everything back together before turning the pump back on after 5 minutes there was still no water moving?
You must purge the air out of the line that sucks the water out of your pool(inlet to pump side).This is usally done by opening a bleeder valve on top of the filter cover. #1 Shut inlet and outlet valve to pool. #2 Clean or change filter and re-install lid. #3 Open pool line valve on inlet to pump side. #4 Open bleeder valve on top of pump until only water comes out,then close bleeder valve. #5 Open pool valve from (pump to pool side) outlet to pool side. #6 Turn pump back on. Running your pump without water for more than a few seconds can damage or burn up your pump.

Where is the inlet and outlet of your pressure tank?
A pressure tank for a pump & well potable water system only has one connection. To connect the pump and tank to your house's water inlet, simply connect the tank and pump together with pressure rated pipe, SCH 40 PVC works fine. In that line, cut in a TEE fitting, and from that T, connect the house inlet with a valve to shut the water off.
What should you do if the top of the sand filter and the fingers at the bottom have both been replaced but there is still sand in the pool and you have already tried backwashing?
Many people mistake "mustard algae" as sand in their pool. Does the sand briefly disappear when you run a pool brush over it? Mustard algae resettles quickly and looks very much like filter sand. We have helped many customers with this problem. Also, if there is truly sand in the pool and you have replaced the laterals, check for any leakage of air around the filter. You may hear or see cavation in the pump when it is shut off.

Where should a service valve be located in order to isolate the hot supply from the hot water supply to the taps?
An isolation valve on the hot side of the domestic water system should only be installed IF there is an expansion tank on the hot water system. This is because if both the inlet and outlet of the water heater are shut off with no expansion tank, the expansion caused by the heating and cooling of the water can cause the pipes to burst. Usually there is only a shut off on the cold inlet side of the water heater. To isolate the hot side of the system you would shut off the cold inlet to the water heater and drain down the hot side. Note that if valves and seals are old and leaking, you will get cross over from the cold to the hot in some of the fixtures themselves, necessitating the need to shut off the cold and drain down the entire system.
