Filter size is 250 sq. ft. at least!!!
Pump size depends on if you have 1 1/2 or 2 in. Plumbing.
I would recommend a Jandy D.E. filter. The BEST!!!! Great filters!!!!!!!!!
Get a 1 or 1 1/2 horse power pool pump and that should do the trick
What type and size is the filter?
More info. How many gallons water? What is the size of the filter? Any other factors that you can include? Ken
The size of your filter limits the size of the pump, a 1 hp sta rite dura glas is great pump a 1hp should do you . If you have solar 1 1/2 hp is needed to push the water up on the roof.
Either a 50 OR A 75 would do it.
A small sand filter 40-60 sq ft. and a small pump 3/4 HP
If, and only if, the horsepowers are the same and the fittings are the same size, yes. Don't change the horsepower of your pump without changing your filter without consulting a professional.
Just get a 1 1/2 horse pool pump and that should do the job beautifully,
You should run the filter on your 18 x 4 pool for at least 6 hours per day or for as long as direct sunlight shines on the pool. In very warm climates, you will need to run the pump for at least 8 hours.
That depends on filter, pump and plumbing size. What else is plumbed into the system. Does it have a pool cleaner attached and how? All this is called or is referred to as the amount of head. Ken
Draining the water from the "pump" (I'm assuming you mean the filter) should only take a few minutes. How long it would take to drain the water in the pool down to the winterization level would depend on the size of your pool and the pump you are using.
Determine how many gallons of water your swimming pool holds. You will also need to consider what size filter that you have. If you have an undersized filter to pump it can create filtration and circulation problems. Be sure to look at the turnover rate for your pump and filter that you are considering. If you have an aboveground pool most pump and filters are sold as a pre-sized set.
Depends on the size of the pump However an average sise pump takes about 5 hours on an ave pool
Is this pressure of water going in a filter or pressure of water coming out a filter? Do you mean increase the flow of water? An increase in the filter pressure alone without going to a larger size impeller or newer pump will only indicate that the filter is getting dirty. If you need more flow consider changing the impeller or even upgrading the pump BUT you have to know what the outcome of that change will be. You have to know what the hydraulics and pump curve is in order to keep from overpumping the water. Too much flow can be detremental to the plumbing, the pump, the heater. Going to a large size pump most likely now increase your flow if the pipes can not handle that extra flow of water. Sometimes whrn a pump is not sized properly - going to a smaller size pump or impeller - whichever the case may be - will increase the flow of water or GPM. There is a is a trick or formula for sizing pool pumps, filters and heaters to a particular pool.
