I think it was me who didn't have the facts straight. I mis-remembered
the length of the warranty but in the end, it didn't matter because the
warranty didn't transfer, even during the warranty period of 10 years.
At the moment, I've plugged six more holes and have a few more to go (had
a party so I had to stop when guests arrived).
I think it's probably a waste of time and effort unless you can get it
to get the pool started. Sounds like it was improperly maintained. Froze?
I'm surprised the panels cost so much. Do they look like this?:
And have you seen this?:
Funny you mention that. I 'thought' of just buying lots and lots of cheap
irrigation tubing and hooking it to the ends.
I'll take a picture of the tubes (having a party today so gotta run ...
will write back later with details).
I bought fifty drip system hole plugs from Lowes, part number 646050 as
shown in this photo below with the Fafco solar heating panel rubber plug
The potential issue is the shape and material is all different as can be
seen in this comparison photo:
Given the Fafco solar heating rubber plug (stopper) measurements:
- Width 1/4" tapered to a smidge over 1/8"; length barely over 7/8"
Here is the original picture of the plug kit:
I think these 50 cent plugs just might work (free shipping over $40):
The measurements are:
- Widgetco Part Number: 7-R000000-EPDM-RS
- Top Diameter: 1/4" | .250" | 6mm
- Bottom Diameter: 1/8" | .125" | 3mm
- Length: 3/4" | .750" | 19mm
- Durometer: 55
- Material: EPDM

Drat. After all that research, I called Poco Solar just now at 3345
Keller Street Santa Clara (408-970-0680) and they charge 54 cents plus
about 10% tax for the plugs.
I don't know how many pinholes there are, but, each pinhole takes at
least two plugs (sometimes more). I'd guess there are about 50 holes, so
that's about 100 plugs. They have the repair tool kit (comes with 20
plugs) for $45 + about $5 tax.
I really wish I could find a rubber string to fit. I'll have to check the
McMaster Carr site again.
BTW, Poco Solar said the "Revolution" panels are $528 but those are the
ones I have which have the 'whorl' pressed into them which creates
thousands of weak points (all the leaks are at the whorl!).
So if I'm going to replace the 12 feet by 4 feet solar heating panels,
I'll need the "Sunsaver" style. Luckily it's better and cheaper at $370
each. (It's amazing that people pay about 150 dollars more for the
weaker, more troublesome Fafco solar heating panels.)

The suggested McMaster-Carr plugs were the best deal:
1/4" x 1/8" x 3/4" PN: 6448K88, $8.46/100 plugs
That comes out to about 9 cents a plug, with shipping.
They're the same size and material as the Fafco solar panel plugs except
for two things (which matter - but which can be worked around).
1. They shorter (3/4" versus 7/8")
2. They don't have the hole in the large end
Personally, I 'wish' I could find longer tapered plugs because the longer
the taper, the easier they plug the tube - but the muuuch cheaper plugs
do work. They're just harder to get inside the tube.
Likewise, I was easily able to create the hole in the large end of the
plugs I bought simply by heating an allen wrench in a flame and using it
to punch a hole in the end of the tapered plugs.
While that worked, it wasn't really necessary so I stopped melting the
hole. The only reason for the hole is to keep the pressure at the center
of the plug when installing so that it doesn't 'bunch up' and bend like
an inchworm as it tries to go into the hole.
The workaround is to use a 1/8" round-tipped tool to push the plug into
the tube hole. It takes more force than with the official Fafco plugs -
but it works.

Interestingly, the package from McMaster-Carr said it was from
Rubber Dynamics (rubberdynamics.com)
which has the plugs (in bulk) cheaper than McMaster-Carr
The problem with Rubber Dynamics is that you can only buy 10 packs of 100
each, whereas at McMaster Carr you can buy 1 pack at 100 each.
They're $5.00 for 100 at Rubber Dynamics (but you need to buy ten packs
which is $50 for 1,000 plugs.

The only difference between this 5 cent plug and the 54 cent Fafco repair
plug is that the Fafco plug is 7/8" long and it has a tiny hole in the
large end for the Fafco allen wrench tool to fit inside.
The hole is easy to make with a heated allen wrench but I really wish I
could find a plug that was 7/8 inch long.
Does ANYONE know where we can buy, in bulk, a standard stopper that is
7/8" long (and 1/4" at the large end, and about 1/8" or so at the small
