Replacing Pentair CCP drain port with a valve and hose attachment

I thought this might be of interest to some people -- I have a Pentair CCP420 filter on a concrete pad with the pumps, and opening the drain makes a big mess everywhere, so I wanted the ability to connect a hose to a better location when cleaning the filter or draining excess water from the pool. Other threads showed this for filters with horizontal drain ports, but the CCP series has the drain plug vertically in a recess under the filter, so putting fittings on is not as simple.

After browsing the local ACE PVC fitting aisle, I came up with:

- 1.5” -> 3/4" reducer
- 3/4" street elbow (male on one end, female on the other)
- 3/4" short nipple
- 3/4" ball valve
- Hose adapter (3/4" male pipe thread on one end, male hose thread on the other, plastic)

By reducing to 3/4" I was able to screw the reducer in, then the elbow into that with plenty of clearance before adding the rest. I used teflon tape on all of the male threads, and it doesn’t appear to be leaking at all.

Obviously this won’t drain as fast as a 1.5” pipe would, but it’s a clear 3/4" path and seems to work fine. It will vary with your pool size, pump speed and plumbing, but I can drain an inch of water in about 20 minutes, so I just set an alarm on my phone or watch to come back and close it up. It’s probably better to have a somewhat restricted flow to keep enough pressure in the filter that air doesn't enter the system.

J,

Thanks for the pics...

I need to do this on my filter, as I'm just getting too old to stand on my head to remove the drain valve... :D

Thanks for posting,

Jim R.

Going to follow your instructions today. We had a ton of rain. What pump RPM do you typically run at when opening the ball valve?

Unfortunately I just tried this and was unsuccessful. My filter sits directly on the equipment pad with barely and space between drain plug and the concrete pad. Was unable to rotate the ball valve to tighten into the PVC without the handle hitting the ground [emoji51]

It was tight; I think I did have to tip the filter ever so slightly to screw on the valve; there was enough give in my pipes to do that. Could you just disconnect the unions from the filter to be able to tip it? Other think I can think of is another street elbow (so the valve ends up vertical) or two (to bring it horizontal again but higher).

I just run at a regular higher speed (I think 2500, but I had set my IntelliFlo's max RPM to something like 2650 to be equivalent to the old 3/4 HP pump). I don't think you have to worry about overpressuring the hose since you're not forcing all of the water there; whatever volume the hose can't handle will go through the normal filter/return path.

Good suggestion. Will try that. What did you use to seal the 1.5 inch to 3/4 inch reducer? Just teflon tape? Did you also use the o-ring from the original drain plug?

Did you use teflon tape or something else to make water tight at each of the couplings and connections?

Thanks again. Am determined to make this happen.

I used teflon tape on all of the threads and I did not use the drain plug's O-ring.
