How To Repair A Leaking PVC Ball Valve Handle

PVC valve handles are susceptible to tears and breakage. Sometimes to snug up water supply, we turn them more than they can bear. For this excess force, the thickness around the valve handle gets uneven. Repeating this process will inevitably break apart the less dense area and cause leaks.

So, a quick tip for you, be gentle with your PVC valves. As the PVC connection sufficiently snugs up when you close it with hand tight force.

Moreover, if your pipe connection is welded or affixed not to tamper with it again, this guide will be handy if you only need to replace the handle. So, let’s initiate the step-by-step instructions. We will start by withdrawing the broken handle:

  • Firstly, switch off your water supply and the adjacent connection valves to prevent backlog water from rushing into the handle pocket. Also, make sure the valve itself is switched on or open.
  • After that, check on top of the valve handle, and you will find a round cap. With a flat head, a screwdriver inserts around the edge without damaging the cap. Then, use the driver as a lever and pull out the cap gently.
  • Now, if you see a screw under the cap, unbolt it with a plus screwdriver. However, if your handle doesn’t have one, get onto the next step directly.
  • Next, turn the handle a quarter clockwise and apply gentle pull pressure, and your handle will come off easily.

Great, we’re halfway there. Now,  put in the replacement handle in the place of the old or damaged handle you just extracted.

So let’s get over with it.

  • First, wear the new handle over the valve and turn it anti-clockwise gently, quarter a turn. Be careful so that the centerpiece doesn’t move with it.
  • Now, put the cap on and bolt in screws if your valve has any.
  • Finally, turn the supply lines open and test the valve. See? No more PVC valve leaking from handle! You’re a great learner.

How To Replace A PVC Valve

Replacing PVC valves is not too tough, but you will still have to put in some effort. However, the replacement process is very straightforward, so there is no need to temporize.

To start the replacement process, make sure the new valve matches the specs of your pipings. Also, Keep essential tools close by hand. Without more delay, let’s start changing your PVC valve:

  • Like the previous procedure and essential for all starting procedures, switch off the supply water valve.
  • Now, if yours is a threaded connection, try unscrewing the fitting with your hand. It will take some force at first, but the connection will eventually loosen up. You can also use a plier particularly made for PVC pipe if the connections are too tight.
  • On the other hand, if your connection is cemented and primed, you need to cut out the pipe to extract the valve. Use a hacksaw to cut and a knife to gently smoothen the pipe ends.

Now that you have detached the valve, we are left with reinstalling a new one. Before doing that, however, you can dry set the whole if your connection is not threaded because you may need a pipe extension and coupler for the right alignment.

Keep attaching the set until you have it. Then proceed on with the next part, at first for threaded connection.

  • First of all, clean the pipe ends and apply Teflon tape in an opposing direction to the rotation so that the tape cover tightens as you thread the pipe in. This will make your connection snug.
  • Secondly, thread the pipe inside the valve coupler until it’s hand tight. Then make a half and a quarter more turn. Use a cloth for better grip. Finally, cover the other pipe with Teflon tape and thread it in the valve duct too. That’s it for threaded connection.

For Unthreaded Valves, Replicate the following Method

  • Dry fit first until you get the suitable adjustment of the pipings. Reinstalling the PVC valve is as easy as establishing a coupler junction. To attach the valve, insert the pipe in and rotate until you feel the closure against the pipe.
  • To make this type of connection tight and leak-resistant, you need to apply primer and PVC cement in each new connection.
  • So, take out the pipes again but remember the arrangement. Now apply primer and cement over the pipe head. Also, put some carefully inside the valve up to the coupler stoppage. Be careful not to spill any cement into the centerpiece.
  • As soon as you finish cementing, shove the pipe in the valve, rotate, and fasten it in as you tightened in the prior drill. Then hold fast for ten seconds to let the connection settle.
  • Repeat the same procedure with the pipe on the other end. Similarly, follow this protocol for all pipe extensions and couplers you may need to append to the valve connection.

Voila! You replaced your PVC valve soundly. But, wait. Switch on the water supply and then turn on your new valve. Very satisfying, isn’t it?

Restoring Valve Connection

If your water leaks simply because of poor valve connection, then check PVC valve leaking. Again, if the problem resides within your valve handle, for instance, leakage under the pipe. Then similar to the valve handle repair method, detach your handle and examine for faults.

Furthermore, if there is a connection problem, like an overturned centerpiece adjusting it will fix the issue. Use the opposite side of the valve handle to clasp and rotate the centerpiece to adjust it. Otherwise, in case of a degraded handle, you have to replace the handle completely.

Unless the centerpiece or valve duct is dysfunctional, you don’t need to replace the whole valve set. It is a good perk that comes with PVC valves. Another part is the repairing process is far easier, and you don’t need professional experience to do it.
