Some noteworthy information about Drain Vacuum Pump
Making sure you look after your pool and spa during the cold months
An important part of maintaining a spa, hot tub, swim spas or swimming pool includes preparing it for those months when you may not be using it. It is believed that pools should be shut when the temperatures at night hit the 40s. If you close it too early, you will risk the possibility of algae overgrowth. If you wait until trees start to shed their leaves, then you may have that mess to cope with.
It is often thought necessary to winterize the plumbing, equipment and pool structure before any of these components freeze. The APSP advise pool owners to thoroughly inspect the pool or spa structure and the equipment to ensure everything is in working order. If something needs to be repaired, you should do it before closing your pool for the season and ideally before the freezing weather sets in.
A vacuum should be used to extract the waste water into appropriate drains. Vacuum on the filter position only if you filter doesn't have a waste indicator. When needed use a pump to vacuum the waste.
It is recommended to carry out this water treatment in the winter so that the water does not become corrosive when the temperature drops to the freezing point or below. Before placing the cover on you need to make sure you add the winter chemicals. It is advisable to check the instructions that come with your chemicals or cover.
After closing the valve on the skimmer line, you should then lower the water level to about 18 inches below the pool’s coping. How far you lower the level will depend on the type of pool. To be certain, it is best to check the instructions or website of your pool cover manufacturer.
Be sure to drain the water and blow water out of all piping. To blow water out of circulation lines it is advisable to use a tank vacuum cleaner on reverse flow or an air compressor. The heater and filter must be drained from water. Throw in some nontoxic antifreeze which is different from car antifreeze. This is accessible at most pool and spa shops. This solution will normally protect water from freezing to 10 ° F / -12° C.
Drain valves thoroughly, making sure that any below water level are securely sealed. It is best to use an electric heat tape for lines below water level that could be exposed to freezing but cannot be drained or filled with antifreeze.
Lights that have less than 18 inches of water above them are best removed. They can be wrapped in plastic and then stored in a dry place.
Drain the pump by removing the plugs and with the help of a wet/dry vac remove all the water from the pump housing and strainer compartment. Try not to remove the drain plugs when adding the antifreeze. The drain hole threads need to be lubricated to stop corrosion.
All filters should be completely drained and drain plugs left out and again apply a lubricant to the threads.
Finally the cover. This should be secured tightly to keep out all the elements until the pool is required again in the Spring!
Questions on Drain Vacuum Pump
How do I drain hot water lines without draining the water heater?
I have a cabin that must have the water lines drained in winter, to avoid lots of plumbing problems in spring. This is a well with a partially underground pump, so the pump is fine, but the lines beyond the cutoff at the pump must be drained. The cold water is no problem, but getting the maximum amount of water out of the hot water lines without draining the water heater is my challenge.When I turn off the faucet at the tank, it causes some water to remain in the pipes. It is not possible to disconnect the pipe at the heater, and after leaving the heater, the pipes are inside the concrete floor and do not emerge until they reach the bathrooms, Next to the heater is a sink, but I don't believe disconnecting that line will cause the others to drain either.
I will worry about the logistics if someone can explain the principle of why the one end being disconnected and the other being connected seems to form a partial siphon or vacuum or whatever it does.
What I would do considering your plumbing setup is to turn off the cold water, which is the input and you seem to know how to deal with it. Then I would disconnect the hotwater output on top of the water heater and open all the hot water faucets in the house and blow air into the flex line on top of the water heater. I am assuming it is a copper flexible line, some are hard plumbed, the air should blow out almost all of the water from the lines. There is another way this can be done, there is a special spring loaded check valve that can be buried in the ground and surrounded by gravel, this device opens up and drains water when pressure is relieved, or at about zero psi. These were invented for underground sprinkler systems, but can be used for other purposes. About the partial vacuum, the system has trapped air and can be relieved by opening the faucet that is the highest of the bunch prior to draining, of course this is with the water pressure turned off.
