  Plumbing Parts

Knowing a little plumbing never hurt a pond builder.  After all - moving water is a very big part of the pond.  Whenever possible we like to use regular PVC plumbing parts that you can pick up at your nearest hardware store because they aren't as expensive as running flexible hose and fittings designed especially for pond building.  PVC tends to lasts longer too.

Sometimes it makes more sense to use the flexible tubing, especially on smaller ponds and with submersible pumps.  There is also a PVC flex that is now available that combines the durability of PVC with the bend-ability of the flex hose.  It won't bend as much as the black flex hose but it makes sense to use it when you don't want the restriction of elbows in the plumbing. 

Some valves and fittings that you can get cheaply are not good to use for ponds.  For example, the spring-type check valve (that prevents water from  flowing backwards) you find at Home Depot or Lowes will greatly decrease the amount of flow from your pump because it restricts the line.  Therefore, we like the flapper-type check valves.  They aren't as easy to find but don't worry - we have them here.

To get more information on plumbing a pond, visit The Pond Doc's Pond Construction Education Center.  Here are a few articles that should be helpful to you when you are deciding upon the sizes and types of plumbing parts you'll need:

Hose & Piping
When purchasing hose - bigger IS better.  Larger hose is less restrictive and improves water flow.  The size of the outlet port of your pump should not dictate the size hose you choose.  For example, Cal submersible pumps come with 1 1/4" outlet ports.  It's common to adapt the port to 1 1/2" (using a readily available adaptor listed below) in order to achieve better flow.

FlexHoseComp.jpg (18033 bytes) Flex Hose, Ribbed
For ponds or waterfalls
1" XH100 $ 1.35 per ft.
1 1/4" XH114 $ 1.89 per ft.
1 1/2" XH112 $ 2.25 per ft.
2" XH200 $ 3.00 per ft.
 
  PVC Flex Hose
White, not ribbed hose is best to use when it is to be buried or if gluing like regular stiff PVC is desired.  Prevents use of elbows and improves waterflow.
1 1/2" PXH112 $ 2.25 per ft.
2" PXH200 $ 3.00 per ft.
 
  Flex Hose, Solid Black
For use on small ponds, cement fountains or spitters
3/4" FH034 $ 1.10 per ft.
1/2" FH012 $ .89 per ft.

Fish-Safe Skimmers
Side skimmers, such as those used on swimming pools, create a hazard for an unsuspecting fish.  The safest skimmer to place on your system is the fish-safe skimmer.

Fish Safe Skimmer
This skimmer can be installed directly into the side of the pond or without making a hole in the liner.  It attaches to a PVC arm that protrudes from the wall of the pond via a bulk head fitting.  Another method would be to use hard PVC and have it attach over the side of the pond.  The basket inside the skimmer floats up with the water level which gives a little room for lower water levels before it begins to suck in air.
AES750B $ 119.95

Eduction Jets
Create flow by guiding returning water around corners.

InductorJetComp.jpg (10683 bytes) Eduction Jet
Threaded male 3/4" ends make it easy to install into bulk head configuration.  
IndJet034 $ 59.95
InductorJetComp.jpg (10683 bytes) Eduction Jet
Threaded male 1 1/2" ends make it easy to install into bulk head configuration.  Larger Jet allows increased water flow preferred in larger koi ponds.
IndJet112 $ 119.95

Auto Fill Valves
We have temporarily taken the Auto Fill Valves off the internet.

Bulk Head Fittings
Bulk Head Fittings make it possible to plumb right through the liner or hard plastic tubs without water leaking where it shouldn't. Use bulk head fittings for installing fish-safe skimmers and induction jets.

BulkHeadFittingComp.jpg (14375 bytes) Bulk Head Fittings, Double Female Threads - Double threaded polypropylene bulk heads provide a watertight solution when a hole is needed in the side of a rubber liner or hard plastic container.  The perfect piece for installing a fish-safe skimmer  or jets through the liner.

CheckValveComp.jpg (29388 bytes) Check Valve
Also known as a backflow preventer, it allows water to flow in only one direction.  Connects to PVC.  Illustrated installation instructions included with purchase.  (Much better to use than standard spring-action valve found at most hardware stores because it does not restrict the flow like the spring-action valve does.)
