5. Use flanged fittings with brass or 

 stainless-steel bolts and neoprene washers. 



6. Use tees for elbows, crosses for tees, 

 and have flanged unions in every line. 



7. Make positive that there are no air 

 leaks on the suction side of the pumps. 



8. Any pilings used to support pipe in 

 the water should have their tops a few 

 inches below low-water mark to prevent 

 the ice from removing them. 



9. Mussels can be killed by closing olf a 

 suction line for a few weeks and using 

 another line. (No steam can be used with 

 the plastic pipe of today.) No chemicals 

 should be used to kill fouling animals. 



10. Use no lead- or copper-base paints 

 in tanks. Use only plastic-base paints. 



11. Pump to a storage tank, and feed 

 station by gravity. 



12. Have the line leading from the stor- 

 age tank to station 2 feet above the floor 

 of the storage tank. 



13. Use fiberglass tanks and holding 

 units. 



14. Do not use lindane or similar insect 

 sprays. 



15. Install an emergency generating 

 plant to take care of lights and a minimum 

 of one pump. 



16. Have one pump capable of being 

 coupled to a gasoline engine. 



17. Have an emergency bypass from 

 one pump to station without going through 

 the storage tank. 



18. Have as short a suction line as pos- 

 sible. Pump from a sump which is fed 

 from deep water through a 5-foot pipe. 



19. Have an automatic alarm system to 

 warn of low water in storage tank. Tele- 

 phone lines can be rented to ring an alarm 

 in several isolated homes or offices. 



20. Have gages on suction and discharge 

 sides of pumps to indicate pump failures 

 and breakdowns. 



21. To clean growth from insides of 

 some pipes, tie old tire chains on a rope 

 and pull through. Have a rope on both 

 ends so that the chain can be pulled back 

 if it gets stuck. 



22. Use as few values and fittings on suc- 

 tion side of pump as possible, and those 

 used should be of high grade. 



23. Have a basket strainer on suction 

 line just before pump to catch detritus and 

 mussels that would otherwise get plugged 

 in pump impellers. 



24. Use circuit breakers instead of fuses. 



25. Drill Yg inch holes in the flapper of 

 the check valve on the discharge side of 

 the pump so that enough w^ater can pass 

 back through the pump rather than 

 throuirh the packings. 



26. Put as few pipes as possible under 

 the ground. 



27. Make the frost-proofing boxes easy 

 to take apart. 



28. When passing through a bulkhead, 

 overhead, or floor with a pipe, leave plenty 

 of room to disassemble, particularly when 

 through cement. 



29. Make sure electrical system has a 

 good ground, and protect from lightning. 



30. When installing drainage system, 

 use a few crosses with blank faces for 

 future additions. 



31. Have plenty of pitch to the floor 

 toward drains. 



32. Do not cover with cement the pipes 

 that are to be used for heating or cooling 

 water. 



33. Use the type of pipe supports that 

 can be easily taken apart and reused. 



34. Where Y-type sediment strainers are 

 to be used, have them made of plastic 

 (PVC) pipe and perforated sheeting. 

 Sediment strainers should be three times 

 the size of the pipe on which they will be 

 used.
