In my water heater closet, there's a (presumably) 4" Oatey type floor drain, with a chrome grid style cover. The condensing, tankless hot water heater has two 1/2" PVC lines that drain into that floor drain. One is from the overflow valve, and one is for the condensate line (which is air gapped, and feeds through a neutralizing filter to the drain). Since neither line puts much fluid into that drain, I simply suspended the lines an inch above the chrome perforated cover.

This utility floor drain itself feeds into the septic tank. Incidentally, we've been in the house eight years since we built it, and have had the tank pumped once about 2-3 yeas ago, and there was nothing to pump, as far as sludge is concerned. We have an alternative septic system installed, with a 500 gallon septic tank, which feeds a 1000 gallon dry well versus a leach field.

I've finally surrendered to the hard water problems, and am installing an iSpring WCF200K compact whole house water softener. It needs a drain source. The research I've done thus far shows that the minimal gray water discharged by the softener during regeneration is acceptable, for draining into the Septic system. However, unlike the other two lines, this one (which appears to be a 1/2" reinforced, clear vinyl tube) will put out 50 to 75 gallons of gray water per regeneration cycle.

I'm looking for a way to modify that drain, to (a) still act as a floor drain for any water which drops or floods into the hot water closet floor, (b) secure the three feeds over or into the drain, and (c) not result in excess water splashing all over the floor. If the water heater floor were a true wet deck, it wouldn't matter that much. However, it was a last minute thought during the house build (long story), to have something on the floor other than particle board in that closet if (actually "when") water hit the floor. I had the tile contractor install tile over RedGard to create a pseudo wet deck, i.e. no slope, no mortar base, no Kerdi membrane, etc.. It's adequate for the occasional spill, but not regular water drainage or flooding.

Does anyone know of a product I could use to funnel the lines into the drain, preferably (gapped) above floor level, replacing the chrome grid cover, attached into the drain, or otherwise, to ensure all the water from the software drain tube ends up down the drain, and not on the floor? I can jerry-rig with the best of 'em, but I'd rather use a commercial purpose=made device.

Thanks!

You may want to search "funnel drain". There are many varieties but all typically made specifically for a drain body. https://www.lowes.com/pd/Jones-Step...mnpOr1MWY8FMvsANOxPYOhu_lrDbmCOuTZDTfFA&gQT=1

Common topic in the "Water Softener" forum.

Here's an air gap design which supports multiple draining appliances, which will typically bolt directly to an existing floor drain cover using 1 SS machine screw and a SS wing nut.

Edit to add: The iSpring web site specifies the iSpring WCF200K is a water filtration system containing KDF55 & Activated carbon media. While a carbon filtration system is usually beneficial for removal of contaminants, it is not a water softener.

Thanks! I saw some specs on something like this on a manufacturer's web site, but after looking (online) at big box stores, amazon, a couple of plumbing supply companies, I came up empty and moved on. This might be the ticket. Pricy, but .. hey, it's brass. (I think the dang drain itself is only black ABS, lol.)

Perfect, also. Will have to find a retail source and check it out. If not this or the brass funnel above, I'd be jury-rigging something similar (but lol, probably not as clean an implementation). My PVC drain pipes don't look that pretty, though.

Edit: I picked one up, but I'm a bit confused on the application. The specs say that the funnel can be solvent welded into a 2" pipe, adjusted larger or smaller by adapters. The one in this picture kind of looks like it's bolted down to the plastic drain screen cover. Not sure how I'll adapt this to my drain, but I'll figure out a way. I don't want it inside the pipe itself, or else the floor drain will be a floor drain no more (for the w.h. closet floor). I'll see what I can do to attach it on top of the drain cover itself, as the seem to have done here. Looks like it may also have a j-hook that goes through the center of the drain cover, and just pulls the funnel down to connect it to the cover. Ez-peasy. Here's a parts list. FYI. Thanks for the tip!

A supplier web link was included directly below the image.

That air gap maybe utilized for 2 alternate installation applications.

Here is an image of the alternate application (shown at the bottom of the linked page).

Simply remove your floor drain cover, insert the SS machine 'J' screw upward through the center opening, fasten the air gap to the top side of the cover using the machine screw and wing nut, then reinstall the cover before clamping the drain tubes to the included tubing support bracket.
