CSV1A leaking at screw on top of spring cage

[SKling]

I have a CSV1A that is leaking at the screw on the top of the spring cage.  It is a slow drip but enough to accumulate water on the floor.  I installed in 2013.  What do I need to replace?

The diaphragm is probably leaking.  That is rare but happens.  You will need a new gut pack to drop in.  It is called an A-Cart on our shopping cart and cost about 90 bucks freight included.  Call if you need some help ordering or replacing.

Thanks Cary.  I placed the order.  I believe I would need to shut off water and drain any pressure, then unscrew the spring cage, drop in the new guts then put it back together.  If there are any other requirements, tips, tricks or instructions (YouTube video maybe?) can you pass them along to me? 

[Cary Austin]

It is easy to do.  Just call me if you need some help.  The only thing anybody does wrong is get the little brass washer (slip ring) upside down.  Make sure the sharp edge of the brass washer is facing up, not down, or it will cut the rubber diaphragm.  If you don't mess with the adjustment bolt it won't even need re-adjusting.

Here is a parts breakdown.

Is there a torque value recommended when reinstalling the spring cage?

[Cary Austin]

Not really.  It tightens against the rubber diaphragm, so just enough to keep it from leaking.
