Blue Devil B8400C Master Blaster

I used this to clean my Hayward vertical grid DE filter. With the Master Blaster I was able to get into the interior regions of my filter - places where my garden hose nozzle just can't reach. Now it does not get into everything because the tube is too large for some areas, but I estimate it increased the cleaning area from about 75% with the garden hose nozzle to about 90%.

Easy to use, works great

Great value over the OEMModel and works just as well

I use this device to rinse sand & other chemicals away from my filter.

Be careful . It will take off on you if you have strong water pressure .works great.

Very cool tool! Helps clean the filter fast... not a cheep marerial

It works-- but should have opposing nozzles to cancel side force

It's a little flimsy, but it works fine.
