How Do I Plumb 2 Pumps With 2 Sand Filters And 1 Raypak Pool Heater

In our last blog nosotros discussed the reasons for changing filter sand as well every bit the need for using a quality brand of silica sand – we recommend Mystic White Two™ silica sand from US Silica. In this blog and the one to follow, I take chosen to focus on the proper method for irresolute the sand in the filter tank.

Although the general idea is "onetime sand out, new sand in", there is much more to the process than you might recall. For this reason I have called to divide up the process into 2 parts.

Earlier we begin, it is worth noting that you need to apply the correct amount of sand that your filter requires. Also much sand and your filter will likely non run correctly or may break when reassembling. Besides little sand and yous volition have cloudy water no matter how much your filter runs. For this reason bank check your filter manufacturer'due south specs. Typically filters hold sand in 50 lb. increments, and so you can safely expect filters to range from 100, 150, 200, 250 lbs., etc. Also, a project such equally this is worth doing correctly and thoroughly, so plan on having all of the items on mitt BEFORE you kickoff!

CHECKLIST OF ITEMS Y'all MAY WANT TO Take BEFOREHAND

CORRECT AMOUNT OF SILICA SAND FOR YOUR FILTER
NEW O-Ring Between THE MULTIPORT AND THE TANK
TEFLON TAPE FOR THREADED FITTINGS
Marriage FITTINGS
SILICONE LUBE (Practice Not use petroleum based lube!!)
ADDITIONAL O-RINGS Equally NEEDED (This is a good time to change while apart)

First and foremost, be certain that the pump is off. You may even want to cut ability to the pump to forbid mishaps. If working on an above footing pool or whatsoever filter that is lower than the pool water level, you will need to block the flow of water out of the pool. This can be washed with threaded plugs (1 ½" standard plumbing thread). Next, remove the filter bleed cap to allow the filter to empty out. Be certain to put the cap back on BEFORE you lose it. The filter cannot run without information technology!

Then depending upon where the multiport valve (the mechanism that allows you to change betwixt filter, backwash, rinse, etc.) is you'll need to open up the tank. If it is on top, you need to disconnect the plumbing or hoses continued to the multiport.

For pools where PVC piping is used and there are no unions, you will need to cutting the piping with a saw. This is really a skilful opportunity to install like shooting fish in a barrel connect/disconnect unions for hereafter ease. A professional person puddle store – like E-Z Test Pool Supplies J! – will take these unions in stock. Subsequently disconnecting all necessary plumbing attachments, y'all may unscrew the fitting that holds the multiport to the tank. Have care when removing this by slowly and gently twisting and pulling the valve upwards to avoid breaking the internal components of the filter. If you take the multiport valve on the side of the filter, you lot will likely take a 2-slice tank and can unbolt and remove the top half of the filter, exposing the sand bed. On either type of filter, be sure to encompass the open portion of the stand pipe going into the filter with record to prevent sand from getting within the pipe – for some filters an upside down Dixie cup works well to cover. Remember, whatever sand that gets into hither will simply blow back into the pool once you're dorsum up and running.

Now it's time to become the onetime sand out of the filter. Although there may exist more than one way to achieve this, here is a short list of Exercise'southward & DON'TS:

DO	DON'T
Utilize A SHOP VAC IF ACCESS TO THE SAND IS Hard.USE A PAPER OR PLASTIC Loving cup TO EMPTY	TIP THE TANK UPSIDE DOWN TO EMPTY – a good way to break internal partsUSE A GARDEN SPADE – another fashion to break pieces insideATTEMPT TO Motion THE Stand Pipe TO THE SIDE OR UPRWARD UNTIL FULLY UNCOVERED FROM THE SAND

In one case your tank is largely empty of sand you'll need to remove the stand pipe and lateral assembly. For some models the laterals (these await like spokes on a wagon wheel) these will rotate upward 90° to a vertical position. Other types of laterals will unscrew from the base of the stand up pipage. Be sure that unless yous are absolutely sure which type y'all have, be very careful in trying to turn these so as to remove the assembly. Once these laterals are out of the way, side by side remove the complete assembly from the tank. At this bespeak inspect these pieces carefully for cracks or harm, as whatsoever unwanted openings will let sand from inside the tank to pass directly into the pool. The fourth dimension to replace defective or even questionable parts is At present! It is at this point that the tank may be thoroughly rinsed with water to remove the rest of the remaining sand.

In our side by side web log we'll pick upwardly from hither giving you tips on how to get information technology all together!…the filter that is. Sad, I'm not a life coach!

Anyway, until next time, keep pond!
